The PVB29-FRSFW-20-C-11 axial piston pump is built by Vickers within the PVB Piston Pumps series and is intended to supply constant hydraulic energy in automated circuits. Its geometric displacement of 61.6 cm³ per revolution fixes the volume moved through the pumping group each shaft turn, while a rated flow of 109.7 L/min at 1800 r/min covers medium-duty actuator groups common in machine tools. A maximum outlet pressure of 140 bar permits the unit to drive cylinders and motors without overstressing internal parts, and a ceiling shaft speed of 1800 r/min supports direct coupling to standard electric motors. Clockwise shaft rotation defines the correct direction for inlet at Port A and outlet at Port B when the pump is mounted with right-hand orientation. The displacement zone is located on one side of center so the swashplate only tilts in a single direction, simplifying control response. These characteristics allow the pump to maintain stable flow and pressure in closed or open center circuits.
Mechanical and control features round out the model’s data. A pilot diameter of 127.00 mm guides centering in the mounting flange for proper shaft alignment, and the 31.75 mm shaft diameter with a 7.9 mm square by 31.7 mm key transfers torque without slip. Two case drain ports threaded 0.750-16 UNF-2B let excess leakage oil return to tank and keep the housing pressure low. System regulation is handled by a type C pressure compensator, identified by control design number 11, so outlet pressure is limited automatically once the set point is reached. Pump design number 20 indicates the internal part revision applied to this size. All working lines share 1.625-12 UNF-2B inlet and outlet port threads to match standard SAE adapters, giving installers a single fitting size across suction and pressure hoses. Together these details support reliable installation, pressure control, and serviceability in automated hydraulic equipment.
