Important considerations when purchasing hydraulic pumps over 3.7kW
Accurately determine pressure: The required pressure is a critical factor in determining the selection of appropriate motor capacity and pump type. Choosing incorrectly can reduce performance or affect equipment lifespan.
Calculate the necessary oil flow rate: The pump flow rate must meet the working speed of the hydraulic cylinder or hydraulic motor. Inappropriate selection can cause the system to operate slowly or waste energy.
Choose the right type of hydraulic pump: Depending on operational requirements, you can choose gear pumps, vane pumps, or other specialized pump lines to achieve optimal efficiency.
Prioritize high-capacity cast iron motor housings: For continuous and heavy-duty working systems, cast iron motors help increase rigidity, heat dissipation capability, and durability during use.
Check installation dimensions: It is necessary to cross-check the flange, shaft diameter, coupling, and the positions of oil ports to ensure compatibility with the existing system.
Pay attention to origin and warranty policy: Products should be selected from reputable suppliers with clear technical specifications, complete replacement parts, and after-sales technical support policies.

Frequently Asked Questions
Why do pump shaft seals continuously fail even after being replaced multiple times?
Aside from seal quality, issues can also stem from worn pump shafts, loose bearings, excessively high return oil pressure, or misalignment between the motor and the pump during installation.
How to inspect and evaluate the wear level of pump shaft bushings without completely disassembling the pump assembly?
Technicians typically combine vibration measurement, bearing temperature, shaft radial runout, and operating noise analysis. Abnormal indicators can reflect bushing wear or shaft misalignment.
How to distinguish pressure drops caused by pump wear from pressure drops caused by internal leakage at valves or hydraulic cylinders?
Technicians usually perform individual load tests on each assembly, combined with measuring pressure, flow rate, and oil temperature at multiple positions within the system. This method helps accurately pinpoint the loss location and avoid misreplacing components.
