Rexroth PV7 Series Variable Vane Pump

Rexroth PV7 variable vane pump unit

Description:

The Rexroth PV7 Series is a variable‑displacement vane pump designed for industrial hydraulics requiring flexible flow and pressure control. Its vane‑and‑stator‑ring design, coupled with hydrodynamically lubricated plain bearings, delivers smooth, quiet, and efficient hydraulic fluid delivery. The PV7’s modular architecture allows variable displacement, precise control, and combination with other pump types — making it ideal for machine tools, hydraulic systems, and general industrial applications.

Rexroth PV7 Series Variable Vane Pump

  • Variable Displacement & Flow/Pressure Control — PV7 supports variable displacement, enabling adjustment of flow and pressure to suit dynamic hydraulic demands.

  • Low Noise & Low Pulsation — Designed for quiet operation and minimal flow pulsation, reducing noise and hydraulic shock.

  • Long Service Life — Use of hydrodynamically lubricated plain bearings provides extended bearing life and lower wear under continuous operation.

  • High Reliability & Precision — Low hysteresis and stable performance with high repetition accuracy make PV7 suitable for precision hydraulic applications.

  • Modularity & Flexibility — PV7 pumps can be combined with other pump types (internal/external gear, axial/radial piston), or configured in multiple‑pump setups to meet complex system requirements.

  • Suitability for Industrial Use — PV7 supports standard hydraulic fluids (e.g. HLP, HETG, HEES, HFD‑U) and fits a wide range of industrial and machine‑tool applications.
