Introduction to PVS Series
The PVS Series Variable Volume Piston Pumps are compact, lightweight hydraulic pumps designed to reduce noise and improve performance. The series includes models with displacement volumes ranging from 8.0 to 45.0 cm³ per revolution and can operate at pressures up to 21 MPa. These pumps are designed to be energy-saving, with a built-in pressure compensator that adjusts the output flow according to the actual load.
The PVS series pump has a swash plate design and uses a variable displacement axial piston. This allows for precise control over the output flow, making it suitable for applications that require high levels of accuracy and efficiency. The pump also features a unique suction port design that reduces noise and increases durability.


Key features of the PVS series
- Compact and Lightweight Design: The pump’s size and weight are reduced in design to reduce noise levels.
- Variable Volume: An adjustment in the pumps’ volume allows for variable pressure dispensation needed in applications.
- Pressure Adjustment: For this reason, this series has various pressure adjusting ranges to accommodate different operating needs.
- Energy Efficiency: They are designed to minimize power loss, hence energy conservations and reduced hydraulic costs.
- Low Noise Operation: These pumps incorporate proprietary quiet mechanisms to achieve silent working properties.
Maintenance and Operational Guidelines
Operating Temperature Range:
- The range of operating temperature for the hydraulic fluid is between 5 to 60°C.
- In case, at start up, oil temperature is less than or equal to 5°C, let the hydraulic pump warm up slowly at low pressure and low operation speed until the oil temperature increases to 5°C.
Filters:
- Use a suction strainer with a filtering grade of approximately 100μm (150 mesh).
- Make certain that a return line filter with a grade of not more than 20μm is provided on the return line back into the tank.
- For high pressure operations (14MPa or above), it is advised that you use a filter or less on this one which has an aperture of around 10µm.
Ambient Temperature Limits:
- Hydraulic operating fluid should be used within an ambient temperature range from0 to60°C.
Energy-Saving Design:
- These pumps have NACHI’s own semi-circular barrel swash plate receiving pressure on its surface, so as to ensure stable discharge volume always.
- This design eliminates surplus discharge volumes and makes it possible for effective utilization of power matching the load cycle.
Noise reduction features:
- There are various proprietary low noise mechanisms installed in parts like shoe, swash plate and valve plate as well. The semi-circular barrel swash plate keeps operation characteristics stable thereby ensuring silent running.
