Voith IPVAP High-pressure Internal Gear Pump for Variable Speed Drives

Low noise and high volumetric efficieny are hallmarks of the Voith IPVAP internal gear pump, which is suitable for variable-speed drives. Hydraulic oil is drawn in between the pinion and internal gear as the gear rotates past the 180 degrees. As the internal gear rotates past the opposing 180 degree position, hydraulic fluid is displaced by pinion teeth ingress into the gear teeth spaces, thereby displacing the hydraulic oil.

  • Internal gear design
  • Voith Superlip (seal lip) provides radial gap compensation
  • Involute (non-cycloidal) gearing
  • High volumetric efficiency
  • Wide range of speed and viscosity
  • Minimal flow
  • Minimal pressure pulsation
  • Compact dimensions
  • Lightweight

Multiple pumps / Pump combinations

IPVAP pumps of all sizes can be combined to create multiflow pumps with the pumps arranged according to frame size and volume delivery. All IPVAP pumps are available as two-flow and three-flow pumps. Custom configurations are available for four-flow pumps.
