What it is
The Sime circulating pump is the primary water circulation component used across the Sime Murelle Advanced and Murelle PRO HE boiler families. It moves heated water from the boiler through the heating circuit and back, maintaining flow rate and system differential. It is supplied as a service part for the models listed below.
Signs this part needs replacing
- Heating circuit fails to reach temperature, or radiators heat unevenly despite the boiler firing
- Pump runs noisily, with grinding, humming or rumbling audible at the casing
- Pump body is hot but the flow pipe stays cool, indicating no circulation
- Boiler locks out or trips on a flow or overheat fault shortly after ignition
- Visible leakage, weeping seals or corrosion staining around the pump head
Before you order
- Confirm the boiler model and product number against the fitment list above
- Check the pump head, seals and connections for damage before removal so the correct part is identified
- Isolate the electrical supply and shut the boiler isolating valves before draining or dismantling
- Verify the system has been cleaned and inhibited, as debris is a common cause of pump failure
