The P75 series gear pump spare parts are a high-quality interchangeable and repairable parts system specifically designed for the P75/P76 series heavy-duty cast iron gear pumps and motors. 100% compatible, it covers a variety of key components including precision gear sets, wear-resistant bearings and thrust plates, shaft end seal kits, drive shafts, pump housings, port end covers, connecting shafts, and external bearings. It supports single, double, and multi-unit configurations. The parts are designed with high interchangeability and quick maintenance in mind, effectively extending the overall pump lifespan, reducing downtime costs, and ensuring long-term stable and reliable operation of the hydraulic system under high pressure and high load conditions.
Gear pump spare parts are core components that ensure the efficient and stable operation of gear pumps. Through precision machining and strict material selection, we ensure that the gears mesh tightly, the seals are reliable, and the parts are wear-resistant and pressure-resistant, thereby effectively improving the pump's volumetric efficiency, reducing leakage and noise, and extending the overall service life.

Q: What precautions should be taken when replacing parts?
A: 1. All parts must be thoroughly cleaned to avoid contaminating the hydraulic oil.
2. The side of the thrust plate with the pressure relief groove must be installed in the correct direction.
3. Note the rotation direction: the position of the check valve or plug determines whether to rotate clockwise or counterclockwise; reversing this will cause the shaft seal to blow out.
4. When replacing the gear set, it is recommended to replace the bearings and thrust plate simultaneously to ensure proper fit.
5. When installing the shaft seal, take care to protect the sealing lip to avoid scratches.
Q: What precautions should be taken after replacing parts?
A: After assembly, a no-load test run should be performed to check for leaks and abnormal noise; confirm that the rotation direction is correct; after the first run, it is recommended to replace the hydraulic oil filter element and regularly check the cleanliness of the oil to extend the life of the parts.
Q: How long is the warranty period for gear pump spare parts?
A: 3-10 months.
