2. Cylinder mounted in polymerous journal bearings

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

3. SAE keyed or SAE splined shaft

  • Heavy duty belt drive shafts available.

4. Sealed front shaft bearing

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

5. Swashblock and saddle with special polymerous bearings

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

6. Steel shoes with specially treated faces for increased fluid retention, running on hardened swashblock surface.

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

7. Hardened cylinder surfacerunning on hardened valve plate (“hard-on-hard”)

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

8. Valve plate selections

  • Rear or side port connections available.

9. Thru-shaft availability

  • Allows for multiple pump installation from a single drive shaft.
  • Allows pumps to drive auxiliary devices.

10. Three frame sizes with seven capacity ranges allowing greater flexibility to selectively match pressure and capacity.

  • Low flow/high pressure to low pressure/high flow from the same frame sizes.

11. Patented presure lubricated swashblock design

  • Provides high peformance for high pressure high cylinder operation.

12. Quite valve plate design

  • Minimizes noise at typicalelectric motor speeds.
