The PVV1-1X/040R belongs to the PV Fixed Displacement Pumps series produced by Bosch Rexroth and supplies constant hydraulic flow to automated machinery. It delivers 39.5 cm³ per revolution, setting the fixed volume transferred each shaft turn. A continuous outlet pressure of 160 bar defines the maximum steady load the casing and bearings can withstand. At 1500 rpm the pump outputs 59 l/min, a value used to size hoses and valves for medium-duty circuits. Clockwise rotation requires matching motor drive orientation to avoid reverse flow. The minimum permissible speed is 600 rpm so internal lubrication remains stable. A top speed of 1800 rpm at 1 bar inlet pressure marks the cavitation threshold that should not be exceeded. Because inlet and outlet are independent, port assignment can be swapped to suit manifold layout. Minimum drive power of 3 kW at 1450 rpm indicates the torque that must be available from the prime mover.
Fluid cleanliness must reach ISO 4406 level 20/18/15 to limit abrasion of the gear surfaces. HLP mineral oil according to DIN 51524-2 is specified as the pressure fluid, providing the viscosity and additive package assumed in the design. An absolute inlet pressure limit of 2.4 bar prevents excessive load on shaft seals, while a minimum of 0.83 bar maintains positive suction at all speeds. The fluid may be as warm as 70 °C, defining the highest working temperature before viscosity becomes too low. Cold-start operation is allowed down to −10 °C, giving flexibility in unheated installations. A maximum viscosity of 860 mm²/s accommodates thick oil during low-temperature starts without pump damage. Minimum viscosity of 13 mm²/s preserves the hydrodynamic film when the oil thins at elevated temperature.
