What it is
The Ariston 65120954 is a circulating pump, designated PARA NFSL/7-50/SC-12, used in Ariston Microgenus II System boilers. It moves primary water around the boiler and heating circuit, so it is central to both heat distribution and domestic hot water production on these appliances. The pump is supplied as a single unit for like-for-like replacement on the models listed below.
Signs this part needs replacing
- The pump does not run when there is a call for heat, or it fails to start intermittently
- Grinding, humming or rattling noise from the pump body during operation
- Radiators and hot water stay cold or heat unevenly because circulation has dropped away
- Water weeping from the pump housing, flange or seal area
- The boiler locks out or cycles repeatedly on an appliance where circulation is suspect
Before you order
- Confirm your appliance model against the two Microgenus II System variants listed above
- Check the pump designation on the existing unit matches PARA NFSL/7-50/SC-12
- Verify the part number 65120954 on the manufacturer's parts list for your boiler
- If in doubt about diagnosis or fitment, have the work carried out by a competent heating engineer
