Cummins Pumps — part numbers

199 numbers covering water pumps, oil pumps, fuel transfer pumps, injection pumps and the repair kits, seals and drive components associated with them.

This category spans a wide range of price and complexity, from a water pump seal kit to a complete injection pump, so the ordering advice differs by type. For water and oil pumps the useful question is whether you want the complete assembly or the repair kit — on many applications both exist, the kit is a fraction of the price, and whether it is worth fitting depends on the condition of the housing and shaft rather than anything we can determine remotely. Ask for both prices and decide with the pump in front of you.

For injection pumps, calibration is everything. A PT pump on a mechanical KTA is matched to the engine's CPL, and a pump supplied without the correct calibration will run the engine but not correctly. Send the code stamped on the pump body itself, not just the engine serial. For electronic engines the same applies to the ECM calibration.

Water pump failures on standby plant in this region follow a recognisable pattern: seal weep, then bearing noise, then coolant loss, usually over a season rather than suddenly. If a pump is weeping, it is worth ordering before it becomes urgent, because the difference between planned sea freight and emergency air freight on a pump is substantial.

On tier, branded aftermarket water and transfer pumps are widely available and often made by the original supplier. Injection pumps we quote genuine or properly remanufactured with a test certificate, and nothing else.

For a quotation, send the engine serial, the CPL, and the code from the pump body where the part is fuel-system.
