Heavy Equipment Parts stocks aftermarket water pumps for excavators and heavy machinery engines. The water pump circulates coolant through the engine to maintain safe operating temperatures — a failing water pump leads to overheating and potential engine damage. Our water pumps are manufactured with quality impellers and sealed bearings for reliable, long-lasting coolant circulation. Compatible with Komatsu, Caterpillar, Hitachi, Hyundai, Cummins, Isuzu, and other major engine platforms. Available from our Sydney warehouse with fast delivery across Australia.
