What is the Grundfos KP 250-A-1 used for?
The Grundfos UNILIFT KP 250-A-1 is a stainless steel submersible pump for non-aggressive water and grey water, including sump, cellar, tank and pool drainage.
What size particles can the Grundfos KP 250-A-1 handle?
The KP 250-A-1 can handle particles up to 10mm and provides a maximum flow rate of 10.5m³/h and maximum head of 10.5 metres.
Does the Grundfos KP 250-A-1 operate automatically?
Yes. It includes a built-in float switch that automatically starts and stops the pump according to the water level.
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.
What types of Grundfos pumps are available?
Grundfos offers circulators, booster pumps, borehole pumps, drainage pumps and other solutions for domestic and commercial systems.
How do I identify the correct Grundfos pump model?
Use the model name and product number on the pump nameplate, then check the electrical, hydraulic and connection specifications.
Can a Grundfos pump improve household water pressure?
A suitably selected Grundfos booster system can improve water pressure or flow, subject to the property’s water supply and installation requirements.
