Grundfos KP Pumps
KP 250-M-1 230v 012K7100
- Established 1975
- Trusted by thousands of customers
The KP range of pumps from Grundfos is suitable for both temporary and permanent free-standing installation, as well as installation within a collecting tank. Easy-to-install, it’s an ideal investment for any water drainage system.
Designed for the pumping of drain water or grey wastewater, the Grundfos KP is a single stage drainage pump complete with a semi open impeller. Versatility is a key benefit of the KP, with all of the models delivered with or without a level switch designated as A, AV or M to suit either automatic or manual installation.
The design of the unit is focused on being robust, constructed from quality submersible stainless steel, with the outer casing being manufactured in one complete piece. The discharge port is placed on top of the pump, with the mains cable and the cable for the level switch combined into one vulcanized and water-tight plug. This in turn is secured to the socket of the stator housing (which is hermetically sealed). The motor is then cooled by the liquid pumped around it.
- Enclosure class: IP 68
- Insulation class: F

What is a submersible pump?
A submersible pump is designed to operate fully submerged in the liquid it is moving. The motor is sealed inside the pump body and cooled by the surrounding water. Submersibles are used for drainage, sewage, septic tanks, deep wells and boreholes, and for raising water from sumps, cellars and floodwater. Many stocked at Anglian Pumping handle solids in suspension.
Can submersible pumps handle solids and sewage?
Yes – some submersibles are designed for clean water only, others handle solids up to 50 mm or full raw sewage. Anglian Pumping stocks ABS, BBC, Flygt and T-T Submersibles ranges that include vortex, single channel and grinder impellers for different solids handling requirements. Always match the pump to the maximum solid size and the type of effluent it will see.
When should I use a submersible pump instead of a surface pump?
Use a submersible when the water level is more than around 8 metres below the pump installation point – surface pumps cannot self-prime beyond that depth. Submersibles are also better when the liquid contains solids, when noise must be minimised, or when the pump needs to operate in confined spaces such as sumps and chambers where a surface pump would not fit.
