Submersible Sewage Cutter Pump

MECHLION MCP cutter pump with Single channel, sewage handling submersible sump pumps with a cutting impeller, capable of pumping semi-screened or grey water of neutral pH. Primarily used for sewage water pumping, the MECHLION Cutter pumps can also be used for sump emptying, septic effluent disposal, water transfer, pumping light slurries and factory waste, or pumping wastewater with stringy or long soft solids in suspension. This attention to detail is an inherent feature of every pump in this series, making it one of the most reliable in the industry.

Why Choose the MECHLION Sewage Cutter Pump

  • Corrosion resistant 304 stainless steel shaft, motor shell and fasteners for a long service life
  • Open impeller and single channel centrifugal design with a cutting leading edge means it is less susceptible to blockage and capable of higher heads and pressure.
  • The ability to cut string like materials and pump soft solids in suspension reduces the risk of blockages in pipework or the pump itself
  • Double mechanical shaft seal in oil bath with hard faced silicon carbide/ceramic seal on pump side gives Added motor protection and long service life.
  • Sand slinger lip seal offer Added protection and long service life.
  • Automatic resetting thermal overload for Protection against overloading
  • Low velocity inlet strainer fitted for a firm and stable positioning during installation and operation and to restrict pumping of solids which may damage or block the pump.
  • HO7RNF oil resistant leads with bare wire lead ends makes it Easy to connect to power supply terminations and long life in dirty water
