What it is

This is a Buderus circulation pump, supplied as part number 73800 and listed under the product name PUMP 1"-130 UPER 15-50. It is a water circulating pump used in Buderus gas boiler installations, moving heating water around the system. It belongs to the Buderus pumps range for gas boiler spares.

Signs this part needs replacing

  • Radiators or hot water stop heating while the boiler still fires
  • The pump runs noisily, with grinding, rumbling or humming that was not present before
  • The boiler reports a circulation or flow fault and locks out
  • The pump body is seized or the shaft cannot be turned
  • Water is weeping from the pump body or its connections

Before you order

  • Confirm the appliance model against the fit list above
  • Compare the part number 73800 with the number on the pump currently fitted
  • Check the pump connections and body against the unit being removed before ordering
  • Verify the fault lies with the pump rather than the boiler control or system wiring
