The PVV52-1X/193-040LA12DUMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and is intended to supply hydraulic automation circuits with a steady flow of pressurized fluid. The displacement of stage 1 is 193.4 cm³ per revolution, providing a high volume transfer per shaft turn, while stage 2 displaces 40.1 cm³ per revolution to service secondary functions. Each stage tolerates 175 bar of continuous pressure, so the pump can support medium-pressure loops without additional relief devices. At 1500 rpm, stage 1 outputs 285 l/min and stage 2 outputs 59 l/min, flow rates that set actuator speed in dual-circuit systems. The allowable operating range spans from a minimum of 600 rpm to a maximum of 1800 rpm when the inlet is held at 1 bar absolute, defining safe drive speeds for stable suction performance.
An SAE-C mounting flange aligns the housing with standard prime movers to simplify installation. The cover side pressure port is threaded for SAE 1 in fittings, and the flange side pressure port is sized for SAE 1 1/2 in connections, allowing each stage to discharge through appropriately matched lines. An SAE 3 1/2 in suction port supplies the gears with low inlet velocity to curb cavitation risk. Rotation is specified as anti-clockwise, guiding motor orientation during assembly. The shaft withstands up to 610 Nm of torque, establishing the upper limit for mechanical loading. Fluid entering the unit must meet ISO 4406 20/18/15 cleanliness to prevent wear in tight internal clearances. The pump weighs 46 kg, a figure that influences lifting methods and bracket design during service.
