Voith IPH pumps are robust and compact high-pressure internal gear pumps with radial and axial sealing gap compensation.
These quiet pumps offer high volumetric and overall efficiency, very good pulsation behaviour and are multi flow capable.
When the gears rotate inside the pump, the pressurised fluid (usually hydraulic oil) is drawn into the cavity between the pinion and internal gear. Optimised cross-sectional areas on both the suction side and pressure side ensure operation over a wide range of speed.
In the radial direction, the gear chambers are closed by gear meshing and the filler piece. When in the axial direction, the axial plates seal the pressure chamber with the minimal possible gap. This design minimises volume losses and increases efficiency.
Voith IPH pumps are available in 9 sizes with displacements from 20.7 cc/rev to 125.6 cc/rev: IPH 4-20 | IPH 4-25 | IPH 4-32 | IPH 5-40 | IPH 5-50 | IPH5-64 | IPH 6-80 | IPH 6-100 | IPH 6-125
Minimum speed across the range is 300 rpm, with maximum speeds varying from 2500 to 3000 rpm. Continuous pressure ranges from 250 bar to 300 bar, with peak pressure ranging from 300 bar to 330 bar.
