The aluminum alloy hydraulic gear pump may have the following problems in actual use. You may not feel it at the beginning, but it will gradually emerge as the use time increases.

Cavitation: This is a common problem that occurs when pumps are operating at high speeds or pressures. It can damage the pump and reduce its efficiency. Cavitation occurs when air or air bubbles form in the pump, causing loss of pressure and fluid flow.

Overheating: If the pump has been running for too long, or if the fluid being pumped is too viscous or hot, the pump may overheat. This may damage the pump and shorten its life.

Leakage: Hydraulic gear pumps rely on seals to prevent fluid leakage. Over time, these seals can wear or become damaged, causing leaks. This can lead to reduced pump performance and potential environmental hazards.

Noise: Hydraulic gear pumps can be noisy during operation, especially at high speeds. This can be troublesome in some applications, or it can indicate a problem with the pump or its components.

Vibration: Excessive vibration during pump operation can cause premature component wear and reduce performance. This can be caused by a number of factors, including misalignment, damaged bearings, or rotor imbalance.
