The PVB29 RSFX 20 CM 11 pump belongs to the PVB Piston Pumps series from Vickers and supplies pressurized fluid for hydraulic automation. It displaces 61.60 cm³ per revolution so flow can be predicted from drive speed, and the displacement control operates on one side of center to vary delivery only in one direction. Permissible speed reaches 2000 rpm, where output can climb to 30 gpm for medium-capacity circuits. Rotation is clockwise when viewed from the shaft end. A straight keyed input shaft provides a secure mechanical link to the prime mover, while SAE flange mounting positions the housing on standard power units. Overall length is 353.9 mm, which helps planners allocate space around the drive assembly.
For piping, the inlet uses a 1.25-inch SAE O-ring port and the outlet uses a 1-1/4-inch SAE O-ring port; both connections share a 1-5/8-12 SAE thread to standardize fittings. Continuous torque on the shaft must remain below 159 N·m, and the compensator can be set as high as 1500 psi to cap system pressure. The pump stands 215.9 mm high and 226 mm wide, dimensions that allow installation inside compact reservoirs. Operating weight is 62 lb, so typical mounting brackets can carry the unit without reinforcement.
