What it is
The Alpha Pump 25-105 is a circulation pump supplied by Alpha for use in its CD-series and Commercial PRO TEC LPG boilers. It circulates heating water through the appliance and the connected system, maintaining flow across the heat exchanger and radiators. The part carries the manufacturer reference 1.028715.
Signs this part needs replacing
- No heating or hot water, with the boiler failing to establish circulation
- The pump body is noisy, rumbling or screeching during operation
- The pump runs hot or the boiler repeatedly locks out on a circulation-related fault
- Water is weeping from the pump body, gland or connection seals
- Radiators or hot water stay cold while the boiler fires and then shuts down
