Definitions

  • the invention refers to a, preferably designed as a well water pump with a reciprocating pumping means and a filter.
  • Pseudo-continuous pumps take over in a first cycle over resiliently biased inlet valve, a fluid in a pumping chamber to this Finally, to compress in a second cycle and an exhaust valve issue.
  • Bohrwasserpumpen take heavily mixed with solids Drilling water at low pressure and provide at separate outputs both filtered Drilling water as well as solids concentrated drilling water at higher pressures to disposal. Due to the strong solid content in the drilling water is a regular Backwash the filter required to avoid permanent clogging.
  • the object of the invention is in the realization of a filtering pump for strong with Solids added fluids. Another aspect is the reliable sealing of the Pumping chamber.
  • a pump for solids contaminated liquids has one Pump drive at least one in a pumping chamber with an inlet valve, a filter and an outlet valve fluidly reciprocable pumping means, which with a ram is drivingly connected, wherein the plunger movable radially back and forth stored and in a circumferentially rotatable about an axis pump drive in a circumferentially variable guide contour is mounted radially form-fitting.
  • the plunger in the guide contour is positively guided over a roller bearing, whereby a sliding friction is avoided.
  • the pumping means on an elastically deformable pumping membrane, which the Pumping chamber slidable and flow-tight partially limited, creating a by the abrasive solids disadvantageous sliding movement of the pumping means is avoidable.
  • the pumping chamber is a concentrate outlet via a concentrate outlet valve associated, which further advantageously controlled by a radial stop of the ram is, whereby a discharge of the solids-enriched concentrate is possible.
  • the pumping chamber can be flown through a spring-biased backflushing chamber associated, which in a relaxation of the pumping chamber, a backwash the filter causes.
  • a pump drive 3 in one circumferentially radially variable guide contour 11 via a roller bearing 12 radially is mounted positively.
  • the pumping chamber 4 is a concentrate outlet 13 via a Concentrate outlet valve 14 associated, which by a radial stop 15 of the Stössels 10 is controllable.
  • the pumping chamber 4 is a spring-biased Assigned backwash chamber 16 throughflow.
  • the pumping membrane 9 is moved radially outward, resulting in the pumping chamber 4 via line 17 with liquid 2 fills. At top dead center of this Movement closes the inlet valve 5.
  • the Pumping means 8 slowly moves radially inwardly, whereby the liquid 2 through the filter. 6 flows and fills the backwashing 16 against the bias.
  • the outlet valve 7 opens and that of solids cleaned liquid 2 is with a pumping effective residual pressure via the line 18th issued.
