Hydraulic piston pumps basic information and selection:
The hydraulic piston pump is the power component of the hydraulic
system. Its function is to supply the oil with a certain flow and
pressure to the system, so it is also the core component of the
hydraulic system. Reasonable selection of hydraulic pumps is very
important for reducing the energy consumption of the hydraulic
system, providing system efficiency, reducing noise, improving work
performance and ensuring the reliable operation of the system. The
principle of selecting a hydraulic pump: the displacement of the
hydraulic pump should be determined first according to the working
conditions of the main engine, the power size and the performance
requirements of the system, and then its specifications and models
should be determined according to the pressure and flow required by
the system.
Customers should determine the following requirements before
ordering hydraulic pumps:
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

Hydraulic piston pumps usage:
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.
