Vickers vane pump V10/V20 series specific parameters
Product Overview
The Vickers V10 and V20 series are fixed displacement, balanced-type vane pumps, designed to meet the needs of modern mobile and industrial hydraulic circuits. They feature a compact structure, long service life, and efficient performance, available in single and double pump configurations for versatile applications. The diametrically opposed internal inlet and outlet pressure chambers balance pressure-induced radial loads, reducing bearing stress and extending service life.
General Technical Parameters
-
Inlet Pressure: Recommended 0 to 0.34 bar (0 to 5 psi) gauge; maximum inlet pressure should not exceed 1.38 bar (20 psi); inlet depressions should not exceed 0.17 bar (5” of Hg or 12.2 psia).
-
Minimum Starting Speed: Generally 600 r/min under standard fluid conditions (SAE 10W oil at 38 to 82°C), which may vary based on pump size, system characteristics and environmental conditions.
-
Fluid Viscosity: Permissible viscosity range is 860 to 40 cst (4000 to 180 sus) when operating with SAE 10W oil, with oil temperature ranging from -12 to 35°C (10 to 95°F).
-
Maximum Continuous Pressure: Up to 172 bar (2500 psi) for most models; some models have lower maximum pressure as specified in the detailed table below.

Additional Notes
-
Maximum rated pump speeds are based on 1 atmosphere of inlet pressure (14.7 psia) at sea level, operating with SAE 10W oil at 38 to 82°C (100 to 180°F) unless otherwise specified.
-
Pumps should not be operated at or near rated pressures at idle speeds for extended periods, as this may cause localized overheating and damage.
-
Optional configurations (e.g., V10F, V10P, V20F, V20P) include integrated flow control valves or priority valves, with slight variations in port connections and weights.
