Product Description

The PV7 series pumps are variable-displacement vane pumps. They are pilot-operated and widely used in low-to-mid-pressure applications in various industries like machine tool and packaging.
 
Structural Features
The pump mainly consists of a housing, cover, rotor, vanes, stator ring, compression spring, set screw, and control plate. The driven rotor rotates within the stator ring, and the vanes in the rotor are pressed against the inner sliding surface of the stator ring by centrifugal force.
 
Performance Characteristics
- Variable Displacement: There are 8 displacement sizes from 14 - 150 cc, suitable for different flow requirements.
- Low Noise: The noise - optimized design through adjusting the height - adjusting screw provides low - operating noise. The hydro - dynamically lubricated plain bearings also contribute to the quiet operation.
- High Control Precision: It has low - flow pulsation, achieving high - repeatability accuracy and low - pressure peaks during downward control.
- Short Response Time: It has very short on - and - off - stroke times, which can quickly respond to system requirements.
- Good Compatibility: It can be combined with many other Rexroth products like internal and external gear pumps, radial piston pumps, and axial piston pumps.
 
Installation and Connection
The mounting and connection dimensions of the PV7 series pumps comply with VDMA 24560/1 and ISO 3019 - 2 standards, which facilitates convenient installation and connection with other equipment.

The PV7 series pumps are widely used in various industrial fields. Here are the details:
- Machine Tool Industry: They are suitable for the hydraulic systems of machine tools such as lathes, milling machines, and grinders. The PV7 series pumps can provide stable pressure and flow, ensuring the precise movement of machine tool slides and the accurate operation of cutting tools.
- Packaging Industry: In packaging machinery like filling machines and sealing machines, these pumps are used to drive hydraulic cylinders for the movement of packaging materials and the operation of sealing mechanisms. Their variable - displacement feature allows for easy adjustment of the flow rate according to different packaging requirements, improving production efficiency and packaging quality.
- Hydrostatic Bearing Systems: The PV7 series pumps are capable of supplying oil to hydrostatic bearings. They maintain a stable oil film pressure to support the rotation of shafts, reducing friction and wear and improving the accuracy and stability of the equipment.
- Constant Pressure Systems: They are often used in constant pressure hydraulic systems. The pumps can adjust the output flow rate according to the system's pressure requirements to maintain a constant pressure, which is crucial for applications requiring a stable pressure source, such as some industrial production lines and hydraulic test benches.
- Engineering Machinery: In certain engineering machinery with low - to - mid - pressure hydraulic systems, such as small - and - medium - sized excavators and loaders, the PV7 series pumps can provide the necessary power. They drive the movement of hydraulic cylinders and hydraulic motors to complete operations such as digging, lifting, and transporting.
