The PVQ40-B2R-B26-SS2S pump belongs to the PVQ Piston Pumps series and is built by Vickers for hydraulic automation systems that need consistent fluid delivery. Its geometric displacement is 41.5 cc per revolution, supplying moderate flow when the pump turns at the rated speed of 1800 r/min. The unit tolerates a maximum operating pressure of 210 bar, and input power reaches 27.6 kW at that limit. Right-hand (clockwise) rotation defines the drive orientation for coupling. The inlet circuit may operate between a 0.2 bar vacuum and 2 bar absolute, permitting flexibility in reservoir placement, while internal case pressure must stay below 0.35 bar to protect seals. A Buna-N shaft seal isolates the drive side from the hydraulic fluid to limit leakage.
The pump mounts on an SAE J744 101-2 flange that matches SAE B interface dimensions. Torque is transmitted through a 1.00-inch keyed SAE B-B input shaft, and a thru-drive SAE B 26-tooth spline allows a second pump to be driven in series. The inlet port is threaded 1.875-12 UN-2B, the pressure outlet uses a 1.3125-12 UN-2B thread, and a .875-14 UNF-2B drain port is located on the bottom at position D2. Approximate weight is 20.6 kg, so a single technician can handle installation with standard lifting equipment. When running at 1800 r/min and 210 bar, the sound level is 71 dB(A), aiding compliance with industrial noise limits.
