High Pressure (Vane)

The Vickers® VMQ is the world leader in pressure capacity and noise levels and is available in a complete range of singles, doubles, triples and thru-drives. The unique wafer plate design of the VMQ allows for the increase in viscosity and pressure rise during cold start-up – something that competitors do not have.

The latest state-of-the-art Vickers® VMQ fixed displacement vane pumps from Eaton set new standards of performance and efficiency for both industrial and mobile applications. The new VMQ series features design enhancements in all areas, resulting in a unique combination of higher pressure capabilities and outstanding low noise levels.

Vickers® VMQ pumps provide continuous pressure ratings up  to 293 bar (4250 psi) for the 25 frame size and displacements up to 488 cm3/r (29.78 in3/r) with the triple pump version. In addition, further reductions in noise levels of an intrinsically quiet design offer real possibilities in traditional internal gear pump applications.

The highly seizure-resistant surface of the bronze wafer plate is particularly forgiving in cold start-up applications.

Performance:

Eaton’s Vickers® VMQ pumps meet global SAE and ISO standards. Three single-pump and three thru-drive frame sizes are available in 20 displacements, ranging from 10 cm3/r (0.62 in3/r) to 240 cm3/r (14.65 in3/r). Four double-pump configurations offer combined displacements from 20 cm3/r (1.23 in3/r) up to 398 cm3/r (24.29 in3/r). Two triple-pump configurations can combine displacements from 110 cm3/r (6.71 in3/r) to 488 cm3/r (29.78 in3/r).

Continuous outlet pressure ratings reach 293 bar (4250 psi), with permissible peak pressures up to 310 bar (4500 psi).
