What it is
The Ariston Para MTSL/7 pump (part number 65120952) is a circulation pump used in Ariston CLAS FF and FF SYSTEM boilers. It moves water through the heating circuit, maintaining flow and pressure for efficient operation. This pump replaces the discontinued 60000591, but the replacement is not a direct swap: it requires cutting into the wiring loom and fitting new plugs.
Signs this part needs replacing
- No heating or hot water: the pump may have seized or failed electrically, preventing circulation.
- Pump runs but no circulation: the impeller may be blocked or damaged, or the pump may be airlocked.
- Unusual noises from the pump: bearing wear or debris in the pump can cause grinding or humming sounds.
- Leaks from the pump body: a failing seal or cracked housing can lead to water loss and pressure drops.
- Boiler lockout or overheat faults: poor circulation can trigger safety devices and shut down the boiler.
Before you order
- Confirm your boiler's GC number and model against the compatibility list to ensure correct fitment.
- This pump replaces 60000591, but it is not a direct swap: the wiring loom must be cut and new plugs fitted.

- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
