Eaton VVS/VVVP series - variable displacement vane pumps
Description:
Maximum displacements to 100 cm3/r (6.1 in3/r).
Maximum pressures to 160 bar (2300 psi).
Vickers variable displacement vane pumps are available in four nominal sizes (0-1-2-3) and are divided into three displacements. Each size, while retaining the same pump body, is available in two versions: low pressure VVS (100 bar, 1500 psi) with mechanical pressure regulator, and high pressure VVP (160 bar, 2300 psi) with hydraulic pressure regulator. The rotor shaft of Vickers pumps is pre-arranged for mounting an additional pump. By removing the rear cover, the secondary pump can be easily attached. Combining standard pumps eliminates the need for many “special application” pumps.
Features and Benefits:
- Long pump life resulting from manufacturing material characteristics, hydrodynamic lubrication of bearings, and hydrostatic balancing of distribution plates.
- Quiet pump operation from 55 to 73 dB(A).
- Simplifies hydraulic circuit by eliminating maximum pressure relief valves and heat exchangers. Pumps can be supplied with various pressure regulators to control the maximum system pressure.
- Standard ISO and SAE mountings.
- Combinations of standard pumps provide flexibility and cost effective pump packages.
