Sime Circulating Pump 6135936

The circulating pump is a Sime component used in Murelle Elite HE boilers. It moves heated water from the boiler around the heating circuit and, where applicable, through the domestic hot water circuit. It is the pump that maintains flow and return circulation across the appliance's operating range.

• The pump runs hot or is noisy, with rumbling, grinding or whining under normal operation.
• Radiators stay cold or heat unevenly despite the boiler firing and the system being correctly balanced.
• The pump head is not turning, or the boiler reports a circulation or flow fault and locks out.
• Flow and return temperature differentials are excessive, indicating reduced circulation.
• The pump leaks from the body, gland or connection points.

• Check the appliance data badge to confirm the exact Murelle Elite HE model and variant.
• Note the GC number on the badge where one is shown, as it identifies the appliance build.
• Confirm the part number on the existing pump matches 6135936 before ordering.
• Isolate the electrical supply and the water connections before removing the pump.
