Hydraulic gear pump has high working pressure of 2900~3600 psi. Displacement 20/30/40/50 Max. GPM for selection, rated speed 1500rpm, maximum 2500 rpm. The hydraulic gear pump has small size and compact structure, applications include industrial/agricultural/commercial machinery, construction machinery, environmental protection equipment, and chemical equipment, etc.

Specification

Features

• Hydraulic gear pump uses high-strength aluminum alloy shell and alloy steel hard gear transmission, which is light in weight and stable in transmission.
• Installation of the hydraulic gear pump is 110 x 86/φ12 standard flange. Input shaft connection is spline. Connection type of the oil inlet and outlet ports is threaded.
• Hydraulic gear pump has an automatic compensation mechanism for axial and radial clearances, which enables the oil pump to maintain high volumetric efficiency and high mechanical efficiency for a long time.
• Hydraulic gear pump uses metric gears, with small fluctuation, high pressure, low noise and stable performance.
• Hydraulic gear pump uses composite material bearings and high-performance sealing elements, has a small starting torque and good tightness, and can work efficiently under harsh working conditions.
• The oil inlet and outlet pipe joints can realize multi-directional inlet and outlet, and can be ordered in any combination according to users.

20/30/40/50 GPM Hydraulic Gear Pump Dimensions Diagram (Unit: mm)

According to the design requirements of 50 GPM hydraulic gear pump, the coaxiality between the rotation axis of the prime mover and the gear pump is not more than 0.1mm.

Tips: How to use 50 GPM hydraulic gear pump correctly?

1. It is recommended to use L-HM46 or hydraulic oil with similar viscosity in summer and L-HM32 or hydraulic oil with similar viscosity in winter. The working hydraulic oil temperature of 50 GPM hydraulic gear pump is -20℃-80℃. If the oil temperature is too high, it will seriously affect the life of the seals. Please choose a reasonable cooling system. In addition, pay attention to check the rated speed and rated pressure of the hydraulic gear pump. Over-speed and over-pressure work will also seriously affect its performance.
2. Do not directly use belt pulleys, sprockets, gears, etc. to make the main shaft bear radial force without the drive bearing installed.
3. When using the 50 GPM hydraulic gear pump for the first time, pay attention to the exhaust of the pipeline, so as not to cause unfavorable phenomena such as unstable pressure, insufficient pressure, insufficient flow, and loud noise.
4. The running speed of 50 GPM hydraulic gear pump should not be lower than 500r/min, so as to avoid insufficient oil absorption, resulting in malfunction and damage to the gear pump.
