1 Voith Turbo IPH Catalog High-pressure internal gear pumps Benefits that impress Internal gear pumps from Voith Turbo are working reliably in hundreds of thousands of machines around the world. Sophisticated technology, robust design and costefficient 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 Compact dimensions, low operating noise levels, minimal pressure and volume pulsation and a high degree of efficiency have always been important customer requirements when it comes to using hydraulic pumps. IPH high-pressure pumps with radial and axial sealing gap compensation have been meeting these requirements extremely reliably for many years now. Machines that run Rarely seen, but hard at work in countless machines, Voith Turbo internal gear pumps reliably provide high pressures. They are mainly used in the plastic and sheet-metal processing sectors, presses as well as conveying and lifting equipment. The pumps are also in demand for shipbuilding, municipal vehicles, power plants and special machine building.

The two smooth running gears help to ensure excellent suction behavior. In the radial direction, the gears chambers are sealed 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 pinion teeth enter the gaps between the internal gear teeth and displace the pressure fluid. Combinations IPH 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, see page 4 and our brochure No. G74 (Voith multiflow pumps). Combinations with third-party products are generally possible. Please contact your Voith Turbo representative for more information. Variable volume flow We supply complete hydraulic units with IPH pumps, asynchronous motors and frequency converters (EPA/ EPAF system) to generate variable volume flows. For further information, see our brochure No. G42 (Voith EPA System). 3

All sizes with each displacement 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 size and delivery. Combination of IPH/IP -pumps It is possible to combine IPH pumps with other Voith Turbo pump series (e.g. medium-pressure pumps IPC/IPM or low-pressure pumps IPN). The pumps are arranged by type and size, 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. Identify the pressure ranges and then choose the appropriate pump series. 2. Identify the deliveries, and then select the appropriate size(s). 3. Define the sequence of the pumps. 4. Check the torque. 5. Determine the direction of rotation and suction.. Specify the mounting flange and shaft end. Connection, assembly As a rule, multi-flow pumps are mounted to the drive using a flange. All information on flange designs and shaft ends is contained in the relevant pump series catalog. For further relevant information, such as how to determine the adapter housing, see brochure No. G 74 (Voith Multi-Flow Pumps). 4
