Manual hydraulic oil pump with pressure gauge:

It can provide power for the cutting tool, the hydraulic compressor, punching machine.and other construction machinery, which is operated in the wild field in electric power,railway, rescue, construction and other industries.

Working principle:

The cam is rotated by the motor. When the cam pushes the plunger upward, the seal volume

formed by the plunger and cylinder block decreases, and the oil is extruded from the seal volume. When the cam rotates to the descending part of the curve, the spring forces the plunger down to form a certain vacuum. The oil in the tank enters the sealing volume under the action of atmospheric pressure. The cam causes the plunger to rise and fall continuously, the seal volume decreases and increases periodically, and the pump continuously absorbs and drains oil.

We have other hydraulic pumping stations:
