The 25V21A 1B22R belongs to the V Series Vane Pumps and is built by Vickers for fixed-displacement hydraulic circuits. It is a vane unit intended to move oil in industrial automation where stable flow is needed. A displacement of 67 cm³ per revolution supplies 21 US gpm when the shaft turns at 1200 rpm and 100 psi, providing a predictable volume for actuators. Clockwise rotation viewed from the shaft end matches common electric-motor drives, while the 1-3/16 in shaft accepts standard couplings and can transmit up to 250 Nm of torque without overstress. Minimum and maximum operating speeds are 600 rpm and 1800 rpm, giving designers flexibility in selecting prime movers. The flange mount simplifies alignment to power-unit plates and maintains pump concentricity under load.
Continuous outlet pressure is limited to 172 bar, allowing the pump to support medium-pressure cylinders and motors without premature wear. Inlet conditions are controlled by a maximum of 1.4 bar and a minimum of −0.17 bar so the cartridge avoids cavitation or seal overload. Ports are supplied as SAE four-bolt flanges, enabling quick removal during maintenance and secure leak-free joints. The outlet is positioned 90° counter-clockwise from the inlet, which assists in routing hoses within compact reservoirs. Total mass is 14.8 kg, light enough for single-person handling yet heavy enough to dampen vibration. These characteristics make the pump a straightforward choice for automated hydraulic power packs that require reliable flow at moderate pressures.
