1. The hydraulic oil pump body is light in weight, easy to use and has high working pressure.

2, single-stage pumping station: simple structure, can get a large working pressure.

3. Double-stage pumping station: When the pressure is low, the high-pressure pump supplies oil at the same time, and a large output flow can be obtained. When the pressure is high, the low-pressure pump automatically returns to the oil through the unloading relief valve. Reduce power consumption.

4, pressure-holding function: in the case of no leakage of the external oil circuit, stop the pump for 5 minutes, the rated pressure does not fall more than 5Mpa.
