It will start pumping at a water level of 20 mm and pump away residual water to 1 mm. The actual level of the residual water may vary depending on factors such as surface texture and composition, evenness of surface etc.


The MF 154HW submersible pump has been designed to cover a wide range of internal and external dewatering applications, but primarily where the temperature of the medium exceeds the standard upper limit (40 °C) to a maximum allowable temperature of 80 °C.

  • Pumping of high temperature discharge water from laundries, commercial dishwashers and washing machines.
  • Filling and emptying of containers, drainage of flooded cellars and removal of rainwater.
  • Suitable for use in septic tanks and pumping effluent from locations below the backwash level in accordance with EN 12056.
  • The vortex hydraulics are particularly suitable for the pumping of fluids containing gaseous or abrasive particles.
  • The compact shape of the MF, fittings for easy mounting, and small sump requirements, ensure a quick and cost-effective installation of the pump.
  • Maximum allowable temperature of the pumped medium is 80 °C (90 °C for max.5 minutes).


The water-tight, fully flood-proof cast iron motor and the hydraulics section comprise a compact, robust, unit construction.


Single-phase 220-240 V, 50 Hz, 2-pole (2900 r/min) motor. Insulation class F; protection type IP68.


The stainless steel rotor shaft is supported in lubricated-for-life ball bearings.

Shaft sealing

Between motor and hydraulic section by means of a high quality mechanical seal of carbon / silicon carbide. Seal at motor side is an oil-lubricated NBR lip seal. Both are independent of direction of rotation and resistant to temperature shock.

Temperature monitoring

TCS (Thermo-Control-System) with thermal sensors in the stator to switch off the pump in the case of overheating and switch on automatically after cooling down.

Hydraulic section with vortex impeller

Free solids passage of 20 mm.


  • Simple, cost-effective, pump installation.
  • Vortex hydraulics for blockage-free pumping in critical applications.
  • Free-standing on legs, or pedestal mounted.
  • Discharge connections G 1½" internal - 1¼" adaptor.
  • Mechanical and lip seals on rotor shaft.
  • Thermal sensors to protect motor against overheating.
  • Float switch for automatic level control.
  • EasyFit plug-in cable connection.
  • Fitted with Europlug
