V10 1B2B 1A20

The V10 1B2B 1A20 hydraulic pump belongs to the Square Vane Pumps series and is manufactured by Vickers. It provides fluid power for small machinery where compact packaging is necessary. A displacement of 0.40 in³ per revolution delivers a precise volume with each shaft turn, allowing predictable flow calculation. The unit achieves an SAE rated flow of 2 US gallons per minute at 1200 rpm and 100 psi, a figure that matches light-duty actuator circuits. Its maximum operating pressure of 172 bar lets it support moderate system loads without overstressing internal vanes. Right-hand rotation defines the correct drive direction so installers can align the coupling with engine or motor output shafts. A two-bolt flange mount secures the housing to standardized pump pads, and the outlet port is set opposite the inlet in position A to simplify line routing inside crowded power units.

The 0.750-inch major shaft diameter transmits torque without excessive deflection, maintaining vane tip sealing during pressure peaks. A square drive key measuring 0.187 inches on each side and 1.25 inches long locks the shaft to the prime mover hub, preventing slip under cyclic loading. Permissible inlet pressure rises to 0.7 bar above atmosphere so the pump can be fed by a low head charge line without risking seal damage. Conversely, allowable inlet vacuum is limited to 5 inches of mercury, a constraint that reduces the chance of cavitation when the reservoir is below the pump level. These parameters guide system designers on line sizing, reservoir placement, and coupling selection, ensuring reliable service in automated hydraulic equipment.
