What it is
The Alpha 3.022793 is a replacement pump head motor for Alpha InTEC and EcoInTEC condensing boilers. It forms the motor and impeller section of the boiler's circulating pump, which moves heating water around the primary circuit. The head mounts onto the pump body inside the appliance and is driven whenever the boiler calls for heat.
Signs this part needs replacing
- The pump runs noisily, humming or grinding when the boiler fires
- Radiators stay cold or heat unevenly while the boiler is running
- The boiler locks out or overheats shortly after ignition
- The flow pipe runs hot but the return stays cold, indicating poor circulation
- The pump head does not run at all when there is a demand for heat
Before you order
- Check the boiler model and serial number against the compatibility list to confirm the correct fitment
- Compare the part number on the existing pump head with 3.022793 and the alternative numbers listed
- Check whether the pump gasket or seal needs replacing at the same time
- Any work inside the boiler casing should be carried out by a competent engineer
