What it is

The Vaillant 0020166558 is a pump supplied for Vaillant VPM series pump units. It circulates water around the appliance and heating circuit, maintaining flow through the system. It is listed for use with the VPM 15 D and VPM 30 D pump units.

Signs this part needs replacing

  • The pump runs noisily, with grinding, humming or rattling under normal operation.
  • Heating or hot water output drops, or flow through the appliance becomes weak or intermittent.
  • The pump body shows signs of leakage, weeping seals or corrosion around the housing.
  • The pump fails to start, stalls, or runs hot and cuts out.
  • The appliance reports a fault relating to circulation or pump operation.

Before you order

  • Confirm your appliance model is a Vaillant VPM 15 D or VPM 30 D pump unit.
  • Check the existing pump against the part number 0020166558 before ordering.
  • Inspect the pump connections, seals and mounting arrangement so the replacement matches the installation.
  • Isolate the appliance and drain down as required before removing the old pump.
