What it is

The Biasi BI1222102 is a motor pump used in Biasi M90 series gas boilers, where it circulates heating water around the system. This version is specified for appliances up to serial number N024590604, and it supersedes the earlier code BI1172114. It is a pump and motor assembly rather than a bare pump head.

Signs this part needs replacing

  • The pump runs noisily, with grinding, rumbling or squealing from the pump body.
  • Heating and hot water stop circulating even though the boiler fires.
  • The pump motor does not run at all when there is a call for heat.
  • Water is weeping from the pump housing, flange or seal area.
  • The boiler locks out on overheat during normal operation.

Before you order

  • Confirm the boiler serial number is no higher than N024590604, as the later build uses a different pump.
  • Check the exact model name against the fit list above, as several M90 variants share the same casing.
  • Inspect the pump isolating valves and connections before fitting, as seized valves will need attention at the same time.
  • Verify the fault is the pump itself and not the boiler control or a blockage elsewhere in the system.
