Rexroth PVV industrial version fixed displacement vane hydraulic pump

The PVV is a fixed (constant) displacement vane pump manufactured by Bosch Rexroth as part of its industrial hydraulics vane pump lineup, which also includes the PV7 and PVQ series. The industrial version is built on component series 1X, spans sizes 18 to 193 cm³, and is rated for a maximum operating pressure of 210 bar. Depending on frame size, the range covers a maximum displacement of 193.4 cm³ and a maximum flow of 285 l/min.

Unlike variable displacement (pressure-compensated) vane or piston pumps, the PVV delivers a constant volume of oil per shaft revolution regardless of pressure. Flow only changes with drive speed. This makes it a straightforward, cost-effective choice for circuits that don't need on-the-fly flow adjustment — think single-speed clamping, lifting, or feed applications running off a fixed-speed electric motor.

Common Industrial Applications

Machine Tools and Clamping Circuits

Fixed flow at a set pressure relief setting is exactly what a clamp, indexing, or feed circuit needs — no compensator to tune, fewer failure points, and a predictable cycle time.

Power Units and Hydraulic Packs

Many OEM power units built for presses, lifts, and material handling equipment specify a PVV because it's a known quantity: predictable flow curve, quiet running near operators, and a cartridge that a maintenance team can swap without re-plumbing the whole unit.

Plastics and Rubber Processing Auxiliaries

Ejector, core-pull, and mold-clamp functions on injection molding auxiliary equipment often use vane pumps like the PVV for their low noise and smooth pressure ripple, which helps protect downstream valves and seals from pulsation-related wear.

Double-Pump Configurations

Where a machine needs two independent flow circuits from one motor, two PVV pump kits can be mounted on a shared shaft. This keeps the footprint compact while allowing each stage to have its own pressure port position — useful in presses that need a fast-approach/slow-press flow split.

Selecting and Replacing a PVV Pump

When specifying or cross-referencing a PVV pump, expert techs generally check five things in order:

1. Frame size and displacement (cm³) — must match the flow requirement at the driving motor's rated rpm.

2. Maximum operating pressure — confirm against the actual relief valve setting in the circuit, with margin.

3. Rotation direction — clockwise and counter-clockwise units are not interchangeable without a different type code.

4. Shaft type and mounting flange — cylindrical vs. splined shaft, and SAE-B vs. SAE-C flange, must match the coupling and motor adapter already in place.

5. Port position and seal material — HLP-compatible NBR seals are standard; confirm compatibility if using fire-resistant or synthetic fluids.

Because the pump cartridge is field-replaceable, many maintenance teams keep a spare cartridge on hand rather than a whole new pump housing, cutting both cost and downtime on a planned rebuild.

Selection Table

Q1: Is the PVV a variable or fixed displacement pump?

A1: Fixed. Flow output changes only with drive shaft speed, not with load pressure. If a circuit needs pressure-compensated or load-sensing flow, Rexroth's PVQ series is the variable-displacement counterpart.

Q2: How long does a PVV pump typically last?

A2: Service life depends heavily on fluid cleanliness, viscosity, and duty cycle, but the hydraulically unloaded shaft and vane design is specifically engineered to extend bearing and vane life compared to simpler unbalanced vane pump designs.
