What it is
The Pump dog 1/2 WSS is a pump drive coupling component manufactured by EOGB for use in its boiler range. The pump dog transmits drive from the motor to the pump shaft, so the circulating pump turns with the appliance. It is listed under the EOGB Other model group.
Signs this part needs replacing
- The pump runs but no circulation is achieved, indicating the drive is not being transmitted to the shaft
- Grinding, rattling or irregular noise from the pump coupling area
- Visible wear, rounding or cracking on the dog's drive lugs or flats
- The pump impeller can be turned by hand while the motor is running
- Repeated pump seizure or loss of heating and hot water circulation
Before you order
- Confirm the appliance model against the fitment list above
- Check the pump shaft and coupling reference to confirm the 1/2 size designation matches the fitted part
- Inspect the mating coupling half and shaft for wear before reassembly
- Retain the old part to compare drive lug profile and dimensions
