1 IPVP High-pressure Internal Gear Pumps for Variable Speed Drives Technical Data Sheet

2 Design and Function a 4b 3 Pinion shaft 2 Internal gear 3 Filler pin 4a Filler segment carrier 4b Filler sealing segment 5 Axial disc 6 Axial pressure area 7 Plain bearings 8 Housing 9 Hydrostatic bearing End cover Suction chamber Pressure chamber Function By rotation of the gears inside the pump, the pressure fluid (usually hydraulic oil) is drawn into the cavity between the pinion and internal gear. Optimized cross-sectional areas on suction side as well as on pressure side allow operation over a wide range of speed. In radial direction, the gear chambers are closed by gear meshing and the filler piece. In the axial direction, the axial plates seal the pressure chamber with the minimal possible gap. This design minimizes volume losses and increases efficiency. 2
