Vickers PVM074 / PVM081 Variable Piston Pump: Specs, Model Code & Parts
Vickers PVM074 / PVM081 (Eaton / Danfoss) are variable-displacement, pressure-compensated axial-piston pumps. Below are the specs for each frame plus the exact in-stock seal kit and rebuild parts. Not sure which one you have? Use the pump identification guide, or see the full Vickers model-code walkthrough.
PVM074 / PVM081 specifications
| Model | Max displacement | Rated pressure |
|---|---|---|
| PVM074 | approx. 74 cm³/r (4.52 in³/r) | High-pressure industrial (per model code) |
| PVM081 | approx. 81 cm³/r (4.94 in³/r) | High-pressure industrial (per model code) |
Single or dual shaft seal?
The Vickers model code tells you: an S in the shaft-seal position means a single (one-way) shaft seal, a D means a double/dual seal. See the full model-code decoder for a worked example. When in doubt, pull the shaft-end cover: one lip seal = single; two seals with a drain between = dual.
Common PVM074 / PVM081 problems — and the parts that fix them
- Oil weeping at the shaft: worn shaft seal — replace the shaft seal.
- External leaks at the end cap / ports: hardened O-rings & gaskets — install the seal kit.
- Won’t hold the compensator setting: worn control-piston or compensator seals — seal kit plus inspection.

Frequently asked questions
What is the displacement of a Vickers PVM074 and PVM081?
The PVM074 is approximately 74 cm3/r (4.52 in3/r) and the PVM081 approximately 81 cm3/r (4.94 in3/r); confirm the exact rating against your model code.
Is my PVM074/081 a single or dual shaft seal pump?
Read the shaft-seal digit in the model code: S is single, D is double/dual.
Do you stock PVM074 and PVM081 seal kits?
Yes. Seal kits and rebuild parts for the PVM074 and PVM081 are in stock and ship the same day.
