The PVV1-1X/046RD pump belongs to the PV Fixed Displacement Pumps series and is manufactured by Bosch Rexroth. It delivers constant hydraulic flow for automation circuits. A displacement of 45.9 cm³ per revolution establishes the volume moved each shaft turn, defining circuit sizing. At 1 500 rpm it supplies a maximum flow of 70 L/min, ensuring steady oil delivery at common drive speeds. Operating speed can rise to 1 800 rpm and drop to 600 rpm, giving flexibility for variable-speed applications. Shaft rotation is clockwise, matching standard right-hand drive arrangements. The unit withstands a continuous outlet pressure of 140 bar, making it suitable for medium-pressure tooling and clamping tasks. HLP mineral oil to DIN 51524-2 is the required pressure fluid so that lubrication and thermal stability are maintained. Installation is via an SAE J744 flange, allowing direct coupling to compliant prime movers.
System cleanliness must reach ISO 4406 class 20/18/15 to limit particulate wear on internal surfaces. Inlet pressure may rise to an absolute 2.4 bar and must not drop below 0.83 bar; these limits prevent cavitation and guarantee a full charge to the pumping chambers. The pressure port sits on the top at 0° from the inlet and uses a SAE 3/4-inch connection, which simplifies rigid line routing above the housing. Suction oil enters through a SAE 1 1/2-inch port sized to keep velocity low and reduce pressure loss. Both connections employ SAE flanges with UNC threads so tightening torque is consistent across installations. The pump weighs 12 kg, allowing one technician to handle mounting or replacement without lifting equipment.
