IPVS High-pressure Internal Gear Pumps Technical Data Sheet

Functional Drawing 5 9 2 8 2 9 4a 4b 3 Pinion shaft 2 Internal gear 3 Filler pin 4a Filler segment carrier 4b Filler sealing segment 5 Axial disc Axial pressure area Plain bearings 8 Housing 9 Hydrostatic bearing End cover with bleeder screw 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 the 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

Combinations of IPVS pumps Combinations of IPVS/IP -pumps IPVS pumps of identical or different sizes can be combined in multiflow pumps. All sizes of the relevant pump volume are available as twoor three-flow pumps; four-flow pumps must be designed by Voith Turbo H + L Hydraulic. The pumps are arranged in increasing order according to frame size and delivery. It is possible to combine IPVS pumps with other Voith Turbo H + L Hydraulic pump series (e.g. medium-pressure pumps IPC or low-pressure pumps IPK). The pumps are arranged by types and sizes as shown in the illustration above. If identical types or identical sizes follow each other, the pump with the higher pump flow is placed closer to the drive. Selection Mounting, assembly. Determine pressure ranges and define the appropriate pump serie(s). 2. Determine pump volume and select the appropriate size(s). 3. Define sequence of the pumps. 4. Check the torques. 5. Determine rotation and suction.. Specify mounting flange and shaft end. Multi-flow pumps are generally mounted to the drive by means of a flange. All information about the flange design and shaft end is found in the catalog of the relevant pump series. For more information, for example about definition of the adapter housings, refer to brochure Multi-flow pumps. 8
