The characteristics of hydraulic pump

There are many factors that affect the service life of hydraulic pumps, besides the design and manufacture of pumps themselves, and some of them are also related to the selection of relevant elements (such as coupling, oil filter, etc.) for the use of pumps and the operation during the test run.

The working principle of hydraulic pump is that the movement brings the change of pump chamber volume, compressing the fluid so that the fluid has the pressure energy.

It must have the condition that the pump chamber has the seal volume change.


1. Aluminum alloy manufacturing, high strength, corrosion resistance, light weight, suitable for various environments.

2. The two-speed characteristic reduces the pressure times, and it is in the state of load work quickly in the low-pressure chamber, which is immediately converted to high pressure and shortens each operation cycle.

3. Equiping with pressure regulating valve, which can adjust control and set working pressure.
