What it is
The Sime 6281625 is a modulating circulating pump used in Sime Murelle gas boilers. It moves primary water around the heating circuit and modulates its output to match demand from the appliance. It is a serviceable component within the boiler's hydraulic assembly.
Signs this part needs replacing
- The pump runs noisily, with grinding, rumbling or whining that does not clear after venting.
- Radiators or hot water stay cold because primary water is not circulating.
- The boiler locks out or shuts down on a circulation or flow-related fault.
- The pump does not respond to demand, running at a fixed speed or not at all.
- Water is weeping from the pump body, housing joint or seal area.
Before you order
- Check the appliance data badge and confirm your model matches one of the fitments listed above.
- Confirm the part number on the existing pump or in the manufacturer's parts list before ordering.
- Investigate and correct any system debris or sludge before fitting, as contamination is a common cause of pump failure.
- Check the electrical plug and pipework connections on your appliance match the pump being supplied.
