The PVQ20 pump is part of Eaton Vickers' PVQ series, which features a robust construction and advanced engineering for superior performance.
It is a variable displacement, axial piston pump that operates on the principle of hydrostatics. This means that it uses the pressure of the hydraulic fluid to convert mechanical energy into fluid power.
One of the key features of the PVQ20 pump is its wide range of displacement options. It offers seven different displacement sizes, ranging from 10 cc/rev to 57 cc/rev. This flexibility allows for precise matching of the pump's output to the specific requirements of the hydraulic system, resulting in optimized performance and energy efficiency.
The PVQ20 pump incorporates a swashplate design, which enables variable displacement. The swashplate is tilted by a servo piston, controlling the angle of the pistons within the pump. By adjusting this angle, the pump can deliver varying flow rates and pressures as demanded by the system. This design also ensures smooth and quiet operation, minimizing noise and vibration.
With a maximum continuous operating pressure of 280 bar (4060 psi), the PVQ20 pump offers high-pressure capabilities, making it suitable for demanding applications. It can handle a wide range of fluids, including hydraulic oils, water glycols, and synthetic fluids, providing versatility in various operating conditions.
The PVQ20 pump features a robust construction with high-quality materials.
The body is made of cast iron, ensuring durability and resistance to harsh environments. The pistons and swashplate are precision machined, ensuring tight tolerances and optimal performance. The pump is also equipped with a robust shaft seal system, minimizing the risk of leakage and enhancing reliability.
To further enhance the reliability and longevity of the pump, the PVQ20 incorporates a hydrodynamic bearing design. This design reduces friction and wear, leading to extended service life and minimal maintenance requirements. Additionally, the pump is designed for easy servicing, with quick access to key components, simplifying maintenance and reducing downtime.
The PVQ20 pump is compatible with various control options, allowing for flexible integration into different hydraulic systems. It can be operated manually, using a pressure compensator, or with electronic control, depending on the specific requirements of the application.
