Vickers PVM018 / PVM020 Variable Piston Pump: Specs, Model Code & Parts
Vickers PVM018 / PVM020 (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.
PVM018 / PVM020 specifications
| Model | Max displacement | Rated pressure |
|---|---|---|
| PVM018 | approx. 18 cm³/r (1.10 in³/r) | High-pressure industrial (per model code) |
| PVM020 | approx. 20 cm³/r (1.22 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 PVM018 / PVM020 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 (02-347284 (single 02-347290 / double 02-347291)).
- Won’t hold the compensator setting: worn control-piston or compensator seals — seal kit plus inspection.

Frequently asked questions
What seal kit fits a Vickers PVM018 or PVM020?
Seal kit 02-347284 covers the PVM018/020; single-seal kit 02-347290 and double-seal kit 02-347291 are available depending on your shaft-seal build.
Does the PVM018/020 come in single and double shaft seal versions?
Yes. The model code shaft-seal digit tells you which: S is single, D is double/dual — and the seal kit differs accordingly.
Do you stock PVM018 and PVM020 parts?
Yes, seal kits and rebuild parts for the PVM018 and PVM020 are in stock and ship the same day.
