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.
