Product Description

Calpeda GXRM Pump with fitted Float Switch

Submersible drain and dirty water pump in stainless steel. Comes with Float Switch, 10m Cable and 3-pin plug.

The Calpeda GXRM is an open single-impeller submersible drain pump in chrome-nickel stainless steel.

The GXRM 9 has a maximum head of 9m and a maximum flow of around 160 litres per minute. It has a 1.25 inch vertical outlet.

The motor is water cooled by the pumped water passing between the motor jacket and the external jacket.

The GXRM can also be used as a dirty water pump as it can pump water with solids up to 10mm grain size. The suction strainer at the base of the unit bas a double row of holes or extra safety against clogging. Please note however, this pump is not suitable for use in sewage or waste water systems. 

This pump can sit on the bottom of a level tank, however if deposits are expected to form at the bottom of the installation pit, a support must be provided to keep the pump raised.


This versatile pump can be used in many situations including;

  • For clean water containing solids up to 10mm grain size
  • For draining rooms or or emptying tanks,
  • For extracting water from ponds, streams or pits and for rainwater collection,
  • For irrigation purposes.

For outdoor use a power supply of not less than 10m should be used in accordance with EN60 335-2-41
