Ravenheat Pump Assembly 1 Inch 780 Series 0009CIR06005/0

The Ravenheat pump assembly, part 0009CIR06005/0, is a 1 inch circulation pump used on the 780 series appliance range. It is the component that drives water around the primary heating circuit, so it sits at the centre of the boiler's ability to move heat from the heat exchanger out to the radiators and hot water circuit. The assembly is listed by Ravenheat for the CSI 85 AAA and CSI 85 AAAT boiler families in both LPG and natural gas versions.

• The boiler fires but the radiators stay cold or heat unevenly, with the flow and return pipes showing little temperature difference.
• The pump is noisy in operation, with rumbling, humming or grating that does not clear after venting.
• The pump body is wet or weeping around the housing or connection points.
• The impeller has seized or the shaft will not turn freely when checked by hand with the appliance isolated.
• Repeated overheat or lockout faults that trace back to poor circulation rather than to the burner or controls.

• Check the Gas Council number and the appliance data badge before ordering, as the CSI 85 AAA and AAAT variants use different configurations.
• Confirm the part number 0009CIR06005/0 against the number printed on the existing pump.
• Have a pump gasket or seal kit to hand if the existing seal is disturbed during removal.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
