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.

Tips: How to use hydraulic gear pump correctly?

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 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.
Do not directly use belt pulleys, sprockets, gears, etc. to make the main shaft bear radial force without the drive bearing installed.
When using the 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.
The running speed of 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.

Hydraulic Gear Pump

I wanted to purchase one but I didn't know if the pump head was compatible with my fluid, and what material the pump head and seals were made out of.

ATO Responded

The seal used in this pump is nitrile rubber.
What is your fluid medium? We also need to know the temperature, pressure, etc. of the fluid.

Can you suggest valving to control the flow of this pump?

Can you suggest valving or other ways to control the flow of this pump?
Maybe simply by adjusting the pump RPM?

ATO Responded

The pressure regulating valve is used to control the pressure, and the RPM needs to be adjusted to control the flow of the pump.
So we do not recommend using valves to control the flow.

I want to order another 3600 psi hydraulic gear pump

The first time I bought this 3600 psi hydraulic gear pump, I asked you many questions, and ATO customer service answered my questions patiently. Due to your excellent customer service, I decided to order another 3600 psi hydraulic gear pump.
