The Parker PV270 is one of the largest displacement models in the Parker PVplus Series variable displacement axial piston pump family. It is designed for high-pressure open-circuit hydraulic systems requiring extremely high flow capacity, excellent efficiency, and reliable operation under heavy-duty working conditions.
With a displacement of 270 cm³/rev, a rated pressure of 350 bar, and a maximum intermittent pressure of approximately 420 bar, the PV270 is widely used in mining equipment, large construction machinery, industrial hydraulic systems, marine applications, and heavy-duty hydraulic power units.
When replacing a Parker PV270 pump, the replacement model should not only match the displacement but also consider:
- Pressure rating
- Open-circuit design
- Control system
- Mounting flange
- Shaft configuration
- Rotation direction
- Hydraulic port arrangement
- Machine operating requirements
The following models are commonly considered as engineering alternatives.
