Abstract

A closed system for generating energy comprising a reservoir, a penstock, and a turbine uses a beam pump to pump the water back to the reservoir. The pump comprises a central vertical support, at least one piston connected to a horizontal rotating or walking beam by way of rocker bolts and linking rods. The reservoir and penstock provide means to power the turbine, the system being regulated by control means. Post-turbine, the fluid, under pressure caused by the shape of the pipes, enters the bottom of one or more piston cylinder, causing the piston to rise and the walking beam to rotate or oscillate about its fulcrum. Hydraulic rams, high tension compression springs act as anti-stall devices or drive inputs, providing energy to the walking beam.

DESCRIPTION

Title of invention: TWIN or DOUBLE PISTON BEAM PUMP.

The present invention relates to a twin piston beam pump, and particularly a pump that incorporates one or more pistons connected to each end of the walking beam.

[1] The present disclosure relates to a liquid / water pumping machine. That when connected to a hydro-electric turbine and externally powered anti-stall devices makes electricity in a new way. Two, Beam Pumps are required to ensure water or liquid is continuously pumped or near continuously pumped or moved to produce a constant supply of electricity. With zero carbon or any other type of toxic emissions, or and dangerous waste materials.

[2] Electricity production from green technology is problematic due to storage problems for Solar Power. Wind Turbines require wind which is not constant.

[3] Conventional electricity production, oil, coal, or gas produces a constant supply of electricity especially for peak electric demand. All produce carbon dioxide that could be warming our planet. ALL OF THEM are finite and shall be completely consumed in the future.

[4] Nuclear produced electricity has major problems with the disposal of nuclear waste, decommissioning of old plants and are costly to build. There is also a major danger of explosion.

[5] Conventional pumped water storage hydro - electric plants. Are expensive to construct and cannot produce electricity twenty- four hours per day.

[6] ALL other conventional water, fluid pumps use more fuel or power to produce electricity via a hydro-electric turbine than the cost of the electricity produced.

[7] Accordingly, there is a need for a novel green technology that can overcome the drawbacks associated with the above present electric production methods.

[8] The present invention has been invented to solve the above problem and provides additional advantages; any fluid such as water is continually recycled through the pump (s) and the electricity turbine (s), ensuring our national, natural, and global resources are not wasted. This produces electricity in a new way.

[9] In accordance with an aspect of the present invention, the pump(s) are taken to existing electrical distribution sites therefore saving time, money, and national resources.

[10] In accordance with another aspect of the present invention, electricity is made as and when it is required and at a consistent electrical voltage.

[11] In accordance with an aspect of the present invention, engineers are now able to design a standardised electric power plant with consistent power outputs.

[12] In accordance with still another aspect of the present invention, no mammal, bird, or fish is harmed in the construction, production and decommissioning of the machines.

[13] In accordance with still another aspect of the present invention, only marginal or nonproductive land is used to position the machine (s). With very little impact on the natural environment. Hard and soft landscaping to be employed. Any noise to be supressed by insulation systems.

[14] In accordance with still another aspect of the present invention, electricity production costs shall be lower in the future.

[15] In accordance with still another aspect of the present invention, the machine to be described as an On Demand' electricity generating plant. As the machine is started and stopped by the opening and closing of valves at any time as required by the operator.

Advantageous Effects of the Invention [16] As described above, the Penman Twin/ Double Piston Beam Pump can be any size. A standardized, electricity production plant is built as per the size of the piston pump and the electricity supply required. The pump and electric turbine can produce electricity from .0000000001W to 100,000,000 Terra Watts (TW). Multiple Beams (Walking Beam) and Pistons are attached to one Central Support or Stanchion or multiple Stanchions. As designed, constructed by a person of the art.

[17] It is the object of the present invention to provide a more convenient fluid, water pump capable of moving, pumping, hundreds, thousands, of litres per second to vertical elevations exceeding one hundred and twenty meters or more by two pumps only.

[18] Electrically driven pumps require an increase in capacity of the electrical generation system, this action adds to cost and complexity. In addition, electrically driven pumps suffer from the inevitable electrical losses in converting mechanical power, to electrical power, and then back to mechanical power. Diesel, Petrol, and Gas driven pumps cost more to operate than the electricity generated and produce toxic gasses and carbon dioxide. It is the object of the present invention to provide a more convenient and cheaper method of pumping water or fluid(s).

[19] In the preferred embodiments of the invention, the pump includes a twin or double piston pumping chamber attached via linkages to a rotating or walking beam. The pumping chamber(s) require an inlet for admitting water, fluid into the chamber(s) and outlets for releasing the fluid, water into the discharge pipelines, to, ultimately return to the penstock tank. The walking beam has pistons attached at each end of the walking beam. The pump works by the simple method of allowing a fluid such as water to enter (under the weight of gravity flowing in a steep downward or vertical direction from header tank one and two (Tl &T2) via suitable pipeline(s), into one piston cylinder(s) chamber(s), at a time. The fluid, water enters the bottom of the piston cylinder via a welded or bolted manifold or and, may be piped directly into the bottom of the piston chambers, below the piston(s).

[20] The piston(s) via its linkage with the beam(s) and externally powered anti-stall devices, working on the walking beam(s). Provides the mechanical, motive force to push the beam UP. The force of water and the externally powered, anti - stall devices, working on the piston(s) and the walking beam(s), provide the driving member and the driven member to, force the beam to rotate, move, or walk, on its Beam Pin or Rocker Connection. Air in the piston cylinder(s) is removed from the piston cylinder by way of a breather or exhaust valve, said valve is closed as water exits the piston cylinder(s). This mechanical action forces the opposite end of the beam to

LOWER or go DOWN, pushing the piston(s) attached to this side of the beam down. Air in the descending piston cylinder is removed by way of opening a breather, or exhaust valve on this piston cylinder and is closed when the piston reaches its lowest position in the piston cylinder(s), chamber(s). Fluid, water enters this piston(s) as described above, this mechanical action produces the pumping effect. A Person of the Art shall fabricate the pump(s) from the drawings attached.

[21] The Piston Pump (s) and Beam(s) may be made from any material such as metal, plastic, wood, carbon fibre or steel. When used to produce electricity. Steel or Carbon Fibre may be used. The Beam Pumps (s) may be any colour or combination of colours. The size of the Beam is dependent on the size of the Piston Casings and the length of the piston (s) arm linkage to the Beam attachment(s). As an example, a twelve-meter casing, cylinder, shall have a twelve-meter piston arm linking to the end of the Beam. The Beam therefore requires a minimum of twelve meters of movement. The central beam pivot pin(s) support stanchion is a minimum of eighteen meters allowing for a minimum of, six-meter movement on the UP and Down rotation of the Beam.

[22] The central pivot connection or rocker bolt may be made of any material such as brick, concrete, plastic, carbon fibre, metal or steel. The Beam Bolt, rocker bolt may be at the centre measurement from the end of Beam(s), the walking beam may be any shape. Parallel motion devices such as e.g. Watt No 2 etc, are connected to both ends of the walking beam to ensure the piston connection rods and attachments move straight up and down into and out of the piston cylinders. Robotic arms may also be used as anti-stall and parallel motion devices. The weight of the beam may be any weight. For the above scenario, example, a beam of a minimum weight of seventy tonnes may be required. A person of the Art shall design and specify the size and weight of beam required.

[23] The said twelve-meter piston by one meter sixty centimetres inside bore. Shall move, or pump four thousand litres per second via the pipeline(s) on a six second beam rotation. As such the Hydro Turbine, maximum output at ninety to one hundred and twenty meters of vertical drop or near vertical drop. (The pipeline(s) length is increased if NOT in the vertical position to compensate for the lack of vertical water, fluid flow to provide the fluid, water pressure required). Produces over three Mega Watts of electricity or more depending on the Turbine specification and type. e.g. Francis, - Pelton, etc. Working at seventy five percent efficacy. The piston may be a Plunger, Ram or Piston type internal fitting. Or any other type of piston as designed by a Person of the Art.

[24] According to the invention, any fluid such as water is held in any suitable receptacle at a higher elevation than the pump (s). A person of the art would call this the 'Header Tank' or 'Penstock Tank'. Two or more pipelines are connected to this tank. The tanks and pipeline(s) size and length of pipeline(s) is determined by the size of the piston(s) and the Hydro Electric Turbine electricity output required. Plus, the degree of slope to provide the motive force required, in the above example, pipeline size may be one meter internal bore or more.

[25] In the preferred embodiments of the invention, the fluid, water is piped into the inlet manifolds, piston cylinders of TWO (2) Beam Pumps with a minimum of FOUR (4) pistons, (one piston minimum attached to the beam ends of two walking beams). The two beam pumps may be positioned in any configuration, parallel or in line. Ditto multiple pistons to walking beam connections. Two beam pumps are required to maintain a continuous or near continuous movement of the fluid, water.

[26] According to the invention, one or more pipeline(s) is connected to the piston(s) manifold(s). The pipeline(s) from Tank Two (T2) said pipeline, may be a minimum of ten meters higher in vertical elevation or near vertical elevation than the fluid, water inlet manifold, said pipeline(s) to be a minimum of twice (x2) the diameter than the pipeline(s) exiting, from the penstock tank.

[27] According to the invention, electrical and Computer Controlled Actuator Ball, Butterfly or other specified Valves are placed at the header tank and prior and post to the piston(s) inlet and outlet pipes. Anti - cavitation devices to be attached to the tank outlets and connected by bolts or welded to the inlet and discharge pipelines. Anti-Water Hammer devices to be placed behind the electrically actuated and or automatic, mechanical one- way water, flow, or check valves. Manual fluid, water flow control valves may be positioned before the pipeline - splitter or manifold(s) pipeline(s) to assist in controlling the water flow entering the piston(s) pipeline(s) to achieve the six second, or more or less, walking beam rotation and as a 'fail safe' measure for shutting down the said piston pumps.

[28] According to the invention, said mechanical, non-electrical, check or one-way valves are installed either side of the piston manifold Inlet and Outlet pipelines, these are bolted into the inlet and outlet pipelines for ease of replacement. Care must be taken to ensure that ALL 'one way', check valves are positioned correctly. These simple valves control the fluid, water entering the piston manifold. Piston force only, opens and closes these valves. Two manual or electrically actuated valves are placed either side of the one-way check valves. Said valves are used for closing the pump(s) for maintenance or replacement of said check vales and may be utilised to support the one-way check valve operation if electrically actuated, by opening or closing in unison with the walking or rotating movement of the beam, or and the opening and closing of said, check valves.

[29] According to the invention, 'Two Beam Pumps' consisting of a minimum of four or more pistons are constructed and are placed on level ground at the zero meter (0 m). Securely fixed to the flat ground surface using concrete, steel piles and or a steel skid support or any combination of all three. A manifold with control valves (as above) is provided to allow controlled liquid such as water to enter pistons one and three from Tank Two (T2) and two and four from Tank One (TI).

(1 & 3, 2 & 4 making a total of four pistons). Or one A, one B, three A, three B. Two A, two B, four A, four Β. (1A IB, 3A 3B - TI. 2A 2B, 4A 4B, TI making a total of eight pistons). If a multiple piston pump is fabricated. Or any combination of pistons. As designed by a person of the art.

[30] According to the invention, further pipeline(s) is connected to the Turbine from Tank one (TI). (If the fluid is water, this machine is called a Hydro Electric Turbine). Water is piped in a downward vertical (or near vertical) direction into the Turbine. The pipeline(s) internal size and length is calculated to provide enough water flow to produce the maximum electricity output of the said turbine. The Turbine spins producing electricity. The electricity is fed to the national electrical grid or to stand alone buildings, factories. As stated above, the said Hydro Turbine may be of any type. e.g. Francis, Pelton -, as designed by a person of the art.

[31] According to the invention, the used or spent fluid, water exiting the said turbine is piped into a second tank. At a higher elevation than the two or more sets of pumps. As stated above, a minimum of one meter, (preferably ten meters) of vertical or near vertical drop is required for the water to enter the said piston manifold for piston one and three or any other combination of pistons. The pipeline internal diameter may be two or more sizes larger than the pipeline(s) from tank one (TI). This shall allow for added velocity of fluid, water to enter the above pistons.

[32] According to the invention, the fluid, water from tank two (T2) is piped as per [31] to pistons one and three. (1 & 3), or to any other combination of pistons. If a multiple piston pump is fabricated. As designed by a person of the art. The connection to the discharge pipe from the hydro turbine to tank two should NOT be sealed. This section of pipe to be larger than the discharge turbine pipe and be open to air. (Or any other method of ensuring NO Back Pressure is possible may be used). This shall ensure that NO back pressure can damage the said hydro turbine. Suitable steel or rigid mesh to be used for safety requirements and to stop debris or insects entering the said pipeline.

[33] According to the invention, water, or fluid overflow pipeline(s) to be connected into the top section of said tank two. Backflow or leakage of water shall occur. Leading to a third tank (T3) or more tanks as designed by a person of the art. Tank three (T3) to be positioned at a slightly lower elevation than tank two (T2). Conventional electric pump(s) to be installed into tank three, or further tanks, with a suitable pipeline(s) returning to said tank one. The said, electric pump(s) is to be operated at night or when low electricity demand occurs. This provides a, 'Closed Loop' water pumping system. With NO wastage of said, fluid, water, possible.

[34] According to the invention, said pipelines and control valves are connected to the said piston inlets and outlets via the said, manifolds. The said inlet(s) and outlets especially from header tank one (TI), and header Tank two (T2) require 'Heavy Wall' steel or high-density plastic pipes with reduced internal bore fittings installed at the said, piston inlet or piston manifold inlet. Ventura devices may be also used, to provide the maximum motive force into the said piston casing(s), cylinder(s), or chamber(s) ensuring the upward movement of the piston(s) and the walking beam. Extreme water, fluid pressure(s) shall be produced especially from the direct water flow pipeline(s) from said tank 1 (TI).

[35] According to the invention, Electrical Pressure sensors are placed onto, into the relevant equipment and connected to a suitable computer by wire or wi/fi. The said sensors shall enable the computer to switch on and off valves and Hydraulic, Pneumatic or any other type of externally powered, piston anti stall equipment as designed by a person of the art, and as per the specifications and software provided by the supplier or and designed by a person of the art.

[36] According to the invention, high tension, or compression springs and, or vertical pistons are added to said, Pump Walking Beam(s) as required to ensure more force is applied to the walking beam(s) than produced by the gravity fed water supply. As the pump(s) is NOT a 'Permanent Motion Machine' [Which is Impossible] This is to ensure that there is NO possibility of the said beam walking or, rotating or, 'STALLING' or, stopping the pumping effect and complies with the laws of physics.

[37] According to the invention, heavier weights may be added to one end of the Walking Beams (pistons 2 and 4 etc). To assist the lower water, fluid pressures contained in said pistons 1 and 3 etc. Externally powered, DC or AC electrically or compressed air driven and said computer controlled, vertical hydraulic or pneumatic piston driven rams shall be attached to the Beams. (DC power may consist of Solar Panels Arrays connected via batteries to the DC hydraulic piston pump system or compressed air, compressor). The Turbine is provided with an extra DC generator.

Finally, due to the low power consumption of today's hydraulic or pneumatic piston packages. Direct AC connection from the AC Liquid, Water Turbine is may be easily achieved.

[38] For ease of understanding. If one hundred metric tonnes (100 mt) of force is required to return the fluid, water back to the said header tank one(Tl). The Beam Pumps using gravity and said reduced bore pipe(s) entering the said, piston cylinder(s) only produce eighty metric tonnes (80 mt). The further twenty, (20 mt) metric tonnes of external power (or more, or less) are, is provided, produced, by means of vertical pneumatic, hydraulic pistons, rams, or any other type of said, anti -stall device(s) acting or, pushing against the walking beam to ensure there is NO possibility of the walking beam stalling or stop pumping. Multiple pistons or other types of antistall devices, may be connected to one or all beams including water driven pistons may also be used. These said, pistons, rams, may be single or double acting. Fixed to the said walking beam or free floating. High tension, compression springs and or Robotic arms may also be utilised. To ensure that it becomes impossible for the said, beam pump, as stated above, to stall or stop pumping in normal use. For a rated one thousand metric tonne piston(s) (1000 mt) pushing a fluid like water to a height of one hundred meters in a vertical direction via a one meter internal diameter (lm ID) pipeline as per the above example, the maximum safe metric tonnage of fluid, water should not exceed fifty percent (50%) of the rated piston failure specification (1000MT). Therefore, for the above scenario less than one hundred metric tonnes of water (100 mt, Actual weight is 78.5mt) are contained in the pipeline. A person ofthe art shall calculate and design the above.

[39] In the preferred embodiments of the invention, the discharged water from the said piston(s) enters the exit pipeline(s) then turn at ninety degrees and return in a vertical or near vertical angle, direction back towards, said, header Tank One (TI). The separate pipelines from the piston pumps may be combined to produce one or more pipe runs to (TI). A person of the art shall calculate the elevation, height, and weight of fluid in the pipes. Also, the externally powered said anti stall devices, to enable the pumps to return the water, fluid directly back to TI. This is the most efficient method of returning fluid, water back to TI via one hundred to one hundred and twenty meters (100m -120m) vertical or near vertical said pipeline(s).

[40] According to the invention, the following method as per Fig 6, may also be installed for extremely high near vertical elevations. Where one hundred + Mega Watt Electricity Turbines may be utilised. Instead of returning the fluid, water directly to TI as per [39]. The water is piped to as second set of two or more beam pumps, Pump Two (P2). Said, Pump Two is positioned at a higher elevation above pump one (the inventor calls this, the first step, back to header tank one (TI)). Further one way non-return valves, devices are to be placed into the pipelines at a minimum of fifty to seventy-five meters from the Beam Pump(s) piston discharge pipe(s), to ensure the water, fluid cannot flow back into the piston(s) and cause a 'STALL' or damage the Beam Pump (s).

[41] According to the invention, Further Ninety-degree bends and straight lengths of pipe are connected to the pipes below the level of maximum elevation of the fluid / liquid in the return pipeline(s). Further ninety-degree bends, straight pipes, valves, and manifolds are connected to the second pump [42] According to the invention, the second set of double beam pumps (P2) is positioned at a lower elevation than the discharge pipelines. The corresponding discharge pipes are connected to i

the inlet pistons on pump two. As per [39] without the need for a third tank. As no turbine is connected. (Though a further Hydro Electric Turbine may be utilised to provide extra electricity. As per the above method).

[43] According to the invention, pipelines are connected to the outlet pipes of all pistons as per above. To a third set of double beam pumps, (pump three P3) this is the third step back to header tank one (TI). Further steps may be required depending on the elevation above zerometer- ground level to tank one.

[44] According to the invention, the final step shall allow the said discharge pipelines, water to enter the said header tank one (T1). Ditto the single beam pump(s) direct system as described in [43]. The water, fluid exists the pipeline(s) and enters tank one. Above the fluid, water contained in TI. A partition in the tank may be provided to keep the liquid in separate zones, or two or more tanks may be used. Thus, closing the loop of pipelines and beam pumps. To provide a circulating fluid/water flow for the entire machine. Fluid, water level gages of any type to be installed to allow adequate time to top up, add extra water as and when required to ensure the smooth operation of the machine.

[45] In the preferred embodiments of the invention, the fuel or motive force to produce electricity and powering the beam pumps is fluid. (For a hydro turbine, the fuel is water). The said external power source(s) as stated above may be (hydraulic) fluid, or air - pneumatic or steel springs or robotic devices or any combination of, all. The water used to be filtered prior to filling tank one and the entire piping system, to ensure no solids or debris may enter the system causing premature ware of the equipment. The water may be rain water captured in a temporary reservoir, or may be pumped from a nearby watercourse, or brought by bowser or tanker.

[46] According to the invention, salt water should be avoided due to the corrosive effects on the internal piston(s) and cylinder(s). Though that said, due to new anti-corrosion coatings such as Three Pack Epoxies and or Graphene Type materials. Sea or contaminated water may be used. An adequate water supply to be on hand when commissioning the machine to ensure the smooth filling of the said machine to avoid air entrapment and dry running. The manufacturer of the Piston Cylinders fits air valves. Anti 'water hammer' devices to be designed at time of purchase from the valve suppliers. Ditto air vents, fluid, water cavitation devices and water, air drainage outlet vales. As described above or, and designed by a person of the Art. Periodic toping-up of TI may, shall be required.

[47] According to the invention, Excluding the mechanical, tension, compression, steel springs, and the mechanical, rotating, rocking, or walking beam(s) connected to the piston(s) and water driven external pistons, the 'of the shelf', electrically actuated valve(s), anti-stall piston(s), ram(s) and robotic arm(s) or device(s). Require an electromagnetic clutch(s), and actuator(s) that includes one or more coils, an electric current may be applied to the coils in order to vary the engagement between the driving member and the driven member, and thereby assist in the control and speed of the said, beam pump(s).

Anti-stall devices 11,13, are conventional (off the shelf) piston(s), of single, free floating or double movement, placed to work in the vertical or any other position, pushing against the walking beam 1. (Note! ALL anti stall devices may be bolted to their vertical stanchions for ease of maintenance, removal and replacement); said, anti-stall devices,11,12,13 (or multiple anti-stall devices), provide an extra driving force to the driven force in unison to the fluid, water, entering the piston cylinder(s), 8. Both actions cause the beam 1 to rotate on the rocker bolt 4; The tension, compression steel spring(s) 12 work by the simple method of stored energy, as the spring is compressed by the walking beam and released as the beam 1, rotates.

This above action ensures that the pumps are working in unison, computer controlled, actuated valves, (Fig 5, 6 of Fig 7) open and close very quickly, ensuring an, almost permanent movement of fluid, water is moved throughout the entire system. 15,16. Backup fluid, water is inevitable, (as the pump is NOT a permanent motion machine) said backup fluid, water is piped 10, to tank(s) three (T3) (Fig 6 of 7). To be conventionally pumped back to tank 1 (TI) (fig 6 of 7). The fluid, water may serve to couple viscously, motion from the driving member to the driven member when the driving member and the driven are engaged. The degree of viscous coupling and, or slippage between the driving member and the driven member and hence the speed of the pumps, are therefore controllable under the action of the beam 1, and anti-stall devices, 11,12,13,17 and 18.

Claims

1. A pump having at least one piston, the pump having at least a central vertical support that is connected via a rocker bolt to a horizontal rotating or walking beam member the member connects to the piston cylinders at both ends of the said walking beam via a mechanical at least one connection member, a parallel motion device comprising of several movable linking rod members is connected to both sides of the said walking beam and said piston arm linkages, to provide motion to the said piston connection arms rod members, fluid transfer and storage means are connected with a turbine to provide a fluid distribution system, a control means regulates the fluid transfer system.

Two pumps comprising of said four pistons (or more) is, are required to provide the pumping effect. The main motive fluid, water is brought to the machine, via tanks and pipes, ensuring, said pump(s)work in unison. Water or fluid entering the piston chamber, under pressure, provides the vertical driving force to the driven force of the beam movement, rotation, for imparting mechanical power to drive the pump. At the maximum movement of the walking beam, said piston chamber is fully filled with water, fluid. The above operation is reversed on the opposite end of the beam and associated piston chamber, the rotating beam pin or fitting is a biasing means for biasing into engagement of the driving member and the driven member.

High tension, compression steel springs, water driven vertical reciprocating rams, pistons are dynamic mechanical anti-stall devices, ditto manual, one-way water, fluid valves, that may not require an electromagnetic actuator. All other anti-stall devices, valves and pumps require, a vertical or rotary driven member for imparting vertical or rotary motion to the walking beam or conventional electric pump impeller, a clutch may be utilised for driving the impeller, a biasing means for biasing into at least partial engagement the driving member and the driven member, and an electromagnetic actuator including one or more coils that may be energised by electric current applied to the coils. The driven member in the absence of engagement between the driving member and the driven member is free to vertically move or rotate about the piston chamber, or drive shaft and to move vertically or axially along the drive shaft towards and away from the driving member; and the driven member is magnetically coupled with the electromagnetic actuator when this is energised to move the driven member vertically and, or axially along the drive shaft so that the driving member may be controllably engaged to vary the speed of the walking beam or the impeller in a conventional electric pump.

2. A pump as claimed in claim 1, in which the driven member vertically moves in unison with the walking beam.

3. A pump as claimed in Claim 2, in in which the driven member is integral with the walking beam.

4. A pump as claimed in Claim 2 or Claim 3 in which the rotating beam, is attached to the driving and driven member being an internal piston, contained in a piston cylinder.

5. A pump as claimed in any preceding claim, in which the pumped fluid, water extends in a gap between the driving member and the driven member to facilitate movement, slippage of the driving member.

6. A pump as claimed in Claim 5, in which the driving member has one or more passages therethrough by which the fluid, water in the gap is in partial communication with the water, fluid being pumped by the movement of the walking beam and piston, until the piston chamber is emptied or filled.

7. A pump as claimed in any preceding claim, in which the biasing means is the rocker bolt, which attaches the walking beam. The mechanical stored power of steel springs, and for anti-stall devices and or motorised valves the biasing means is the electromagnetic actuator.

8. A pump as claimed in any of Claims 1 to 7, in which the water, fluid entering the piston chamber(s) produces a force that opposes the biasing means. For anti-stall devices and motorised valves, the actuator when activated produces a force that opposes the biasing means.

9. A pump as claimed in any preceding claim, in which the driving member includes a first engaging feature and the beam and piston includes a second engaging feature, the first engaging feature engaging the second engaging feature, so that the rotation of the beam is engaged directly with that of the driving feature.

10. A pump as claimed in Claim 1 to 9, in which the anti-stall device(s) may, be predominantly placed on the underside of said beam pump horizontal walking beam(s). Between both sides of the said vertical stanchion. Said anti-stall device(s), work in unison, with the movement ofthe walking beam and the piston movement. To ensure added, extra force is applied to the said walking beam. To ensure that water, fluid is returned to the header, penstock tank and ensure the rotation of the beam(s) cannot stop moving or pumping.

The recirculating of water via the said Beam Pumps product of claim 1 to 10, is now possible due to the technological break throughs in computer recognition of electrical / pressure sensors in and on the said beam pumps and associated equipment to ensuring the smooth operation of the said beam pumps, conventional electrical water pumps and water level gauges.

A twin or double beam pump for pumping liquid, water via tanks, pipelines, and hydro-electric turbine to produce electricity, substantially as herein described, with reference to or as shown in the accompanying drawings.
