Product Details

Well drilling machine hydraulic piston pumps lifetime technical support

Hydraulic piston pumps basic information:

Hydraulic piston pump is an important device in the hydraulic system. Hydraulic piston pump relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve oil absorption and oil pressure.

Hydraulic piston pumps main features:

Axial variable displacement piston pump.
Hydraulic piston pumps have swash plate structure.
Be suitable for hydrostatic transmissions with closed-loop circuit.
Manual Servo and Hydraulic Variable control
Variable Displacement Pumps with a charging oil pump and Fixed Displacement Motor with an integrated valve.

Hydraulic piston pumps usage:

a. Piston pumps are widely used in high-pressure, high-flow, high-power systems and occasions where the flow needs to be adjusted, such as agricultural machinery, construction machinery, mining and metallurgical machinery, and ships. It can play an important role.

b. Piston pumps are used in petroleum exploration and development, petrochemical, pharmaceutical, atomic energy science, environmental science, process equipment, experimental equipment, etc.

Hydraulic piston pumps selection:

Customers should determine the following requirements before ordering:

1. Hydraulic pump and motor displacements.

2. Rotation direction of hydraulic pump.

3. Hydraulic shaft type and shaft teeth quantity.

4. Control mode.

5. Usage of hydraulic pump motor.

6. Send label or pictures as more as possible
