The PVB20 LS 20 C11 pump belongs to the PVB Piston Pumps series from Vickers and is intended to supply regulated hydraulic power in automated machinery. Its pressure-compensator control limits outlet pressure automatically so the circuit does not exceed the commanded setting. A displacement of 42.80 cm³ per revolution establishes how much fluid the pump delivers each turn, while the maximum flow of 20 gpm defines the highest continuous volume it can supply to actuators. An input speed ceiling of 1800 rpm protects internal parts against excessive velocity, and the straight-keyed shaft enables direct coupling to common electric motors. Anticlockwise rotation when viewed from the shaft end must be matched by the prime mover, and the 1-1/4 in SAE O-ring inlet port provides a low-restriction path for fluid entering the housing.
A continuous torque demand of 159 N·m specifies the drive capacity required to keep the pump turning under rated pressure. The 1-1/4 in SAE O-ring outlet port delivers pressurized fluid to system lines, while a 0.750-16 UNF-2B SAE O-ring case-drain port returns internal leakage to the reservoir. A separate 1-5/8-12 SAE O-ring threaded port supports auxiliary connections when needed. Installation planning is aided by an overall length of 353.9 mm, a width of 226 mm, and a height of 215.9 mm, ensuring the unit fits standard power packs. The pump weighs 57 lb, a figure that informs mounting hardware selection and lifting procedures.
