Description
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 (see items A and B on page 4). Combining standard pumps eliminates the need for many “special application” pumps. As shown in the cross-sectional views, pumps consist of:
(1) Body
(2) One-piece shaft and rotor
(3) Vanes
(4) Pressure ring that changes the eccentricity and therefore the displacement of the pump, at hydrostatic axial compensation
(5) Pressure plate stator to provide the passage of oil from the suction port to the pressure port
(6) Guide block balancing adjustment screw
(7) Displacement adjustment piston that regulates the maximum pressure compensated flow
(8) Maximum volume adjustment screw (optional feature – see model code page 5)
(9) Pressure regulator
(10) Pressure regulator adjustment
Features & Benefits
Long pump life resulting from manufacturing material characteristics, hydrodynamic lubrication of bearings, and hydrostatic balancing of distribution plates
Quiet pump operation from 66 to 73 dBA
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.
