Wet spraying machine hydraulic piston pumps connect additional
pumps
Hydraulic piston pumps product description:
Hydraulic piston pumps features:
- Series 20 axial piston variable displacement pumps are well
engineered and easy to handle.
- Bearings of variable axial piston pumps are all tapered roller
bearing, which can load heavy external axial forces.
- Hydraulic pumps can be connected with other additional pumps.
- When hydraulic pumps operated mechanically, the Servo displacement
can control and keep the angle of swash plate and pump
displacement.
- Upon release of the control handle, swash plate return to zero
position automatically and the flow reduces to zero.

Hydraulic pumps advantages and usage:
Because the piston pump has high pressure, compact structure, high
efficiency and convenient flow adjustment, it can be used in
systems that require high pressure, large flow, and high power and
in occasions where the flow needs to be adjusted, such as
agricultural machinery, construction machinery, mining and
metallurgical machinery, and shipbuilding industry etc other wide
range of applications.
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
