Submersible Dewatering Sump Pump

MECHLION MDP series high head submersible sump pumps are designed for commercial and industrial dewatering, groundwater transferring, effluent transferring, and car washing applications. These pumps include a stainless motor housing, and they are designed to provide great heat dissipation from the motor, ensuring a long service life. All pumps are 100% pressure-tested, submerged and run to ensure quality and reliability for years of trouble-free performance. 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 Dewatering Pump

  • Corrosion resistant 304 stainless steel shaft, motor shell and fasteners for a long service life
  • Open impeller, centrifugal design to pump soft solids in suspension, less susceptible to blockage and Capable of higher heads/pressure.
  • 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
