Voith IPVS 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 IPVS pumps are available in 22 sizes with displacements from 3.6 cc/rev to 251.7 cc/rev: IPVS 3-3.5 | IPVS 3-5 | IPVS 3-6.3 | IPVS 3-8 | IPVS 3-10 | IPVS 4-13 | IPVS 4-16 | IPVS 4-20 | IPVS 4- 25 | IPVS 4-32 | IPVS 5-32 | IPVS 5-40 | IPVS 5-50 | IPVS 5-64 | IPVS 6-64 | IPVS 6-80 | IPVS 6-100 | IPVS 6-125 | IPVS 7-125 | IPVS 7-160 | IPVS7-200 | IPVS 7-250
Minimum speed across the range is 400 rpm, with maximum speeds varying from 1800 to 3600 rpm. Continuous pressure ranges from 265 bar to 345 bar, with peak pressure at 1500 rpm ranging from 300 bar to 420 bar.
