Voith Turbo IPV catalog High-pressure internal gear pumps Benefits that convince Internal gear pumps from Voith Turbo are working reliably in hundreds of thousands of machines worldwide. Sophisticated technology, robust design and cost-efficient operation have convinced thousands of customers to trust Voith. Based on that trust, we have become the world market leader for high-pressure internal gear pumps with gap compensation. Features that count The market requires hydraulic pumps that are quiet and compact with minimal pressure pulsations at simultaneously high efficiencies. Voith Turbo has met these requirements with the IPV pumps, which feature radial and axial sealing gap compensation with volume-optimized involute gearing. Machines that run Rarely seen, but hard at work in countless machines, Voith Turbo internal gear pumps reliably provide high pressures. Their main applications are machines in the plastics and sheet-metal processing sectors, presses as well as conveying and lifting equipment. These pumps are also in demand for shipbuilding, municipal vehicles, power plants and special machine building.

Motor operation possible (energy recovery!) Function Rotation of the gears within the pump draws in the pressure fluid (usually hydraulic oil) into the space between the pinion and internal gear. The two smooth running gears help to ensure excellent intake behaviour. 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. When the gears rotate, the tooth heads enter the gaps between teeth and displace the pressure fluid. Combinations IPV pumps can be combined to form dual or multi-flow pumps. Combinations with other Voith Turbo pump series are also possible. Used in conjunction with pumps from the medium and low-pressure series, Voith equipment can handle a wide range of potential applications. For further information on possible combinations, refer to page 9 and brochure G74 (Voith multi-flow pumps). Combinations with third-party products are generally possible. We'll be happy to discuss your needs. Variable volume flow We supply complete hydraulic units with IPV pumps, asynchronous motors and frequency converters (EPA/EPAF system) to generate variable volume flows. For further information, refer to our brochure G42 (Voith EPA system). 2 3

All sizes of the relevant pump volume are available as two- or three-flow pumps; four-flow pumps must be designed by Voith Turbo. The pumps are arranged in increasing order according to frame size and delivery. Combinations of IPV/IP - pumps It is possible to combine IPV pumps with other Voith Turbo pump series (e.g. medium-pressure pumps IPC or low-pressure pumps IPN). 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. 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. Mounting, assembly Multi-flow pumps are generally mounted to the drive by means of a flange. All information about the flange designs and shaft ends is found in the catalog of the relevant pump series.
