Vickers PVM axial piston hydraulic pump

Description:

The Eaton Vickers PVM Series is a family of open-circuit, variable-displacement axial-piston pumps engineered for industrial hydraulic applications. With displacements ranging from 18 to 141 cc/rev, these pumps combine compact design, high efficiency, and excellent pressure capabilities. The PVM series is particularly suited for systems where space is limited but reliable, high-performance flow control is critical — such as injection molding machines, small presses, conveyor systems, and material handling equipment.

Advantages of the Eaton Vickers PVM Series Piston Pump

  1. High Pressure Capability: The PVM rotating group is proven to handle continuous pressures up to 315 bar (4,600 psi).

  2. Very Low Noise: The teardrop‑shaped housing helps reduce fluid-borne noise significantly (reports of ~9 dB reduction).

  3. Long Service Life: High-load bearings, a stiff drive shaft, and a cradle-bearing design support long life under industrial duty, with some sources noting 8,000 hour L10 life.

  4. Compact Footprint: Thanks to cradle-bearing and optimized internal design, the pump achieves a strong power-to-size ratio.

  5. Variable Displacement Control Options: Multiple control options (pressure compensator, torque limiter, power control, load sense, etc.) make the PVM highly flexible.

  6. Energy Efficiency: Variable-speed compatible, and the optional power control helps the system use power more accurately, lowering heat generation and potentially reducing cooling requirements.

  7. Quiet and Smooth Flow: Low pressure ripple (~4%) reduces shock in systems, contributing to smoother operation and reduced wear.

  8. Certification Options: Some PVM models are ATEX / UKEX certified for use in explosive atmospheres.
