What it is

The Alpha 1.A090 pump head motor is the motor and impeller head used on the circulating pump of Alpha heating appliances. It is the moving half of the circulator: the motor, rotor and impeller that sit on the pump body and drive primary water around the heating circuit. Alpha is the manufacturer, and the part sits in the standard water heater and heating appliance range.

Signs this part needs replacing

  • The pump runs but the heating circuit stays cold, with little or no flow at the radiators
  • Grinding, humming or rattling noise from the pump body when the appliance fires
  • The pump head is hot to touch but the impeller is not turning
  • Repeated overheat or lockout faults on the appliance
  • Visible leakage, corrosion or a burning smell around the pump head

Before you order

  • Match the part number ALPHA1.A090 against the marking on the existing pump head
  • Check the appliance model and serial number against the manufacturer's literature
  • Confirm whether the pump body, seals and gaskets are being retained or replaced at the same time
