About this pump

The Grundfos SEG.50.31.2.50B is a 3.1 kW grinder pump from Grundfos, for a three phase (400V) supply.

It grinds solids before pumping, so sewage can be pushed through small-bore pressure pipes.

Price £3,928.08 inc VAT (£3,273.40 ex VAT), with free delivery to mainland Great Britain. We order it in for you and email the dispatch date.

Before you order

  • Check your supply: this is a three phase (400V) pump.
  • Check the duty: the pump must reach your total head at the flow you need. Use the datasheet curve, or ask us.
  • This version has no built-in float. It needs floats and a control panel, or an existing panel to run it.
  • Fitting is not included. We can install it or swap your old pump.
