The PVQ45B2RB26SS2S10CM710 unit belongs to the PVQ Piston Pumps series and is manufactured by Vickers for closed-loop hydraulic automation. It delivers a displacement of 45.1 cm³ per revolution to provide consistent volumetric flow to cylinders and motors. Operation at a rated speed of 1800 r/min keeps output stable in standard power packs. A maximum working pressure of 186 bar supports medium-pressure circuits without overloading system components. The CM7 control holds the swashplate so outlet pressure tracks the commanded set point. Right-hand clockwise rotation matches common engine directions in mobile machines. A straight keyed SAE B-B input shaft couples directly to electric or diesel prime movers. The SAE J744 101-2 mounting flange positions the housing on a B-pattern interface for quick interchange. Side ports built to the SAE J514 standard keep tube runs short in compact manifolds.
Case pressure is limited to 0.35 bar, so the drain line must remain unrestricted to the tank. An inlet pressure ceiling of 2 bar prevents aeration when boost pumps or elevated reservoirs are used. The inlet connection is threaded 1.875-12 UN-2B to admit low-velocity oil, while the outlet connection uses a 1.3125-12 UN-2B thread to withstand full discharge force. A separate drain port with a 0.875-14 UNF-2B thread returns internal leakage for cooling. The shaft seal is molded from nitrile (Buna-N) to resist standard hydraulic fluids and temperature ranges. A thru-drive featuring an SAE B 26-tooth spline allows a secondary pump to be mounted in tandem. The airborne sound level is 71 dB(A) at the specified test condition, meeting typical factory noise limits.
