Definitions

  • the present disclosure relates to a pump assembly. More specifically, the present disclosure relates to a modular structural configuration of the pump assembly.
  • non-submersible pumps such as a garden pump, a pressure tank unit, and an electronic pressure pump. Such pumps may be used for different applications as per usage requirements. Different types of pumps differ from each other in terms of parameters such as type of components, component designs, component placement, fluid flow patterns, operating conditions etc. However, all these pumps have at least some components which are common across all variants. More specifically, all types of pumps have a motor with associated hydraulics.
  • the garden pump is the simplest type of construction. This pump requires a pipe in front of the hydraulics, which leads to the entrance on the suction side of the pump. After the hydraulics, the pumped medium is pumped via the hydraulic chamber to the pressure-side outlet. To fill the pump, there is a filling opening on the suction or pressure side. For the draining of the fluid inside the pump, there is a drain opening on the pressure side.
  • the pressure tank unit compensates small leakages and pressure fluctuations in the pump with the help of a tank pre-filled with air.
  • the tank is connected on the pressure side of the pump. Furthermore, this design requires sensors for detecting the pressure level of the tank. This is also located on the pressure side. To prevent the emptying of the tank after switching the pump off, the tank, the pressure pipe with sensors and the outlet area are separated from the rest of the pressure side by a non-return valve.
  • the electronic pressure pump detects various operating states with electronics.
  • the detection of the operating states usually works via a sensor in the form of a flow sensor and a pressure sensor.
  • the flow sensor is in the pressure line and the pressure sensor is also located on the pressure side. Further, a check valve prevents the pressure lines from being emptied after the pumps have been switched off.
  • the modular pump assembly includes a pump housing containing an impeller arrangement driven by a drive motor, preferably arranged inside the pump housing, such that the drive motor is adapted to drive a fluid at an entrance of the modular pump assembly to a pressure chamber upstream of the main flow direction of the fluid.
  • the fluid exits the pressure chamber via a first fluid channel and at least one second fluid channel.
  • the first fluid channel includes a first end and a second end such that the first end of the first fluid channel is fluidly coupled with the pump housing.
  • the at least one second fluid channel includes a first end and a second end such that the first end of the at least one second fluid channel is fluidly coupled with the pump housing.
  • the modular pump assembly is characterized in that the second end of the first fluid channel is adapted to be fluidly coupled with one or more first pump component. Further, the second end of the at least one second fluid channel is adapted to be fluidly coupled with one or more second pump component.
  • the present disclosure advantageously provides a modular pump assembly.
  • the modular pump assembly allows to manufacture different types of pump assemblies such as garden pump assembly, pressure tank unit assembly and electronic pressure pump assembly in a cost-effective manner.
  • the modular pump assembly utilizes the pump housing which is common across different types of the pump assemblies.
  • the pump assembly acts as a universal platform to manufacture all types of pumps.
  • the pump housing is fluidly coupled with one or more pump components required to manufacture different types of pump assemblies. This allows reduction of overall number of parts and processes required on manufacturing different types of pumps. Only a single type of pump assembly is manufactured, and later on fitted with appropriate pump components to get desired type of pump assembly.
  • the second end of the first fluid channel is fluidly coupled with the second end of the second fluid channel.
  • the first fluid channel and the second fluid channel are fluidly coupled using one or more connection pipes.
  • the fluid coupling may serve to completely drain the modular pump assembly during the modular pump assembly decommissioning, among other benefits.
  • the first pump component is an outlet pipe
  • the second pump component is a flow pipe.
  • the first pump component and the second pump component may be selected as per the application requirements of the modular pump assembly.
  • the flow pipe might function as a drainage pipe to drain fluid from the garden pump assembly. Additionally or in an alternative embodiment the flow pipe might be connected to a fluid reservoir. Further, the first pump component and the second pump component may be more than one component to advantageously increase the utility of the modular pump assembly.
  • a non-return valve is adapted to be engaged with the outlet pipe.
  • the non-return valve may serve to maintain pressure in the first pump component and the second pump component of the modular pump assembly even when the modular pump assembly is not operating.
  • a pressure tank unit is coupled to the flow pipe.
  • the modular pump assembly is advantageously coupled to the pressure tank unit.
  • the pressure tank unit may supplement the pumping operation of the modular pump assembly. Further, the pressure tank unit may allow the drive motor of the modular pump assembly to be switched OFF while still maintaining the pressure required for the execution of various domestic and industrial operations.
  • a flow measurement impeller is adapted to be engaged with the flow pipe. Different applications may require different fluid flow requirements. Hence, the flow measurement impeller may help in providing the right amount of pressurized fluid for the modular pump assembly applications.
  • FIG. 1 illustrates a modular pump assembly 100, which may be used for irrigation, water supply, sewage movement among other domestic and industrial applications.

  • the one or more first pump component 120 is only one first pump component 120.
