Oilgear PVWJ Hydraulic Pump

Features and Benefits

 1. Multiple control types

  • Field interchangeability without disconnecting from drive or system piping.

2. Cylinder mounted polymerous journal bearing.

  • Allows operation with special fluids.
  • Provides infinite bearing life.
  • Permits compact design.

3. Hardened cylinder surface running on hardened valve plate (“hard-on-hard”)

  • Provides greater resistance to contamination.
  • Provides longer life
  • Allows operation with special fluids.

4. Quiet valve plate design

  • Minimizes noise at typical electric motor speeds.
  • Rear or side port connections available.

5. Thru-shaft availability

  • Allows for multiple pumpin stallation from a single drive shaft.
  • Allows pumps to driveauxiliary devices.

6. Three frame sizes

  • Ten capacity ranges allowing greater flexibility to selectively match pressure and capacity.
  • Low flow/high pressure tolow pressure/high flow from the same frame sizes.

7. Steel shoes with specially treated facesfor increased fluid retention, running on hardened swashblock surface.

  • Provides a higher degree of contamination resistance.
  • Allows higher pressure operation with long life.
  • Allows operation with water base, low viscosity or other special fluids.
  • Provides longer life.

8. Special polymerous saddle bearings

  • Allows running on low viscosity or other special fluids.
  • Permits consistent control reaction.
  • Eliminates troublesome yoke bearings.
  • Provides long life.

9. Patented pressure lubricated swashblock design

  • Provides high performance for high- pressure.
  • high-cylinder operation.

10. Sealed front shaft bearing

  • Allows operation with special fluids.
  • Permits side loading.

11. SAE keyed or SAE splined shaft

  • Heavy duty beltdrive shafts.

  • For higher speeds, please contact us. Higher speeds available – consult factory.
    These units are designed to run with fluids in the 65 to 2000 SSU range.
  • Note: Minimum speed 600 rpm.
PUMP COMBINATIONS

Two or more Oilgear axial piston variable delivery pumps can be integrally coupled together and driven from a single shaft.

Pump deliveries can be combined for large volume circuits or deliveries can be used individually. See page 5 for individual pump ratings.

The front pump can be used at full rated output while the rear pumps are governed by the thru-shaft torque listed in the table below.
