U5K Submersible Sump Pumps

The U5K is a very powerful and versatile submersible pump for both permanent and portable use.

Thanks to the removable sieve basket, it is possible to increase the throughput diameter from 10 mm to 20 mm. This basement wastewater pump also has an integrated flushing device to reduce the accumulation of deposits and a shallow, built-in suction system for the disposal of floodwater.

The Pumps

The U5K is an extremely powerful and versatile centrifugal submersible pump for both stationary and portable use. The pump is suitable for faecal-free wastewater with solids up to 10 mm particle size. Thanks to the removable strainer base, it is possible to increase the free passage to 20mm.

Stationary in a basement chamber or a collecting tank, with an automatic switch attached, the U5KS handles all dirty watr arising from domestic drainage sources such as washing machines, dishwashers, washstands, etc.

Deposit accumulation in the reservoirs and chambers is reduced to a minimum by means of a flushing device. The guide rail system GR 32 offers all the advantages of fast and easy maintenance. If the sump or tank runs dry temporarily, the pump can be vented by providing a drill-hole in the spiral housing.

The U5K can be used as a portable unit for dealing with dirty water from garden ponds, flooded cellars or discharge chambers in laundry rooms or storage rooms. Thanks to its shallow, built-in suction system, it can reduce residual water level to no more than a few millimetres.

If submersible pumps are used outdoors, only a pump with 10m cable without extension cable may be used in accordance with VDE Regulation 0100. For construction sites and garden ponds, a H07-type cable must be used.

  • Reduce deposits in the sump by activating the pump`s integrated flushing device
  • Vent the pump by providing a drill hole in the spiral housing. The sump can now remain dry intermittently
  • Use the swing-type check valve provided only during portable use. In stationary use, the contents of the pressure pipe could suddenly become discharged if the pump was to be dismantled, and this would impede working
