Voith IPVA pumps are high-pressure internal gear pumps with radial and axial sealing gap compensation.
These quiet pumps offer high 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 IPVA pumps are available in 18 sizes with displacements from 3.6 cc/rev to 126.2 cc/rev: IPVA 3-3.5 | IPVA 3-5 | IPVA 3-6.3 | IPVA 3-8 | IPVA 3-10 | IPVA 4-13 | IPVA 4-16 | IPVA 4-20 | IPVA 4-25 | IPVA 4-32 | IPVA 5-32 | IPVA 5-40 | IPVA 5-50 | IPVA 5-64 | IPVA 6-64 | IPVA 6-80 | IPVA 6-100 | IPVA 6-125
Minimum speed across the range is 400 rpm, with maximum speeds varying from 1800 to 3600 rpm. Continuous pressure ranges from 210 bar to 300 bar, with peak pressure ranging from 250 bar to 320 bar.
