The PVV4-1X/098RD pump belongs to the PV Fixed Displacement Pumps series and is manufactured by Bosch Rexroth for hydraulic automation circuits where constant volume delivery is required. It delivers 97.7 cm³ per revolution, so volumetric output remains proportional to shaft speed. A continuous pressure rating of 175 bar allows stable supply to actuators in medium-pressure systems. When driven at 1500 rpm the pump reaches a flow of 141 l/min, while the permissible speed window spans from 600 rpm to 1800 rpm provided the inlet pressure is 1 bar. Clockwise rotation defines the drive arrangement and coupling orientation. Operation demands HLP mineral oil conforming to DIN 51524-2, and the fluid cleanliness must reach ISO 4406 class 20/18/15 to prevent accelerated wear and to maintain service life.
Installation uses flange mounting to SAE J744 with an SAE C flange, enabling direct attachment to standard power take-offs. The pressure port is an SAE 1 1/4-inch connection positioned on the top line with the inlet at 0°, and it is secured with a 7/16-14 UNC fixing thread to keep high-pressure joints tight. The suction side employs an SAE 2-inch port fastened by a 1/2-13 UNC thread, giving low restriction for oil entry. These port standards simplify hose selection during system assembly. The unit weighs 23 kg, so mounting hardware must support that mass and withstand vibration. Together these mechanical features integrate the pump into mobile or stationary manifolds while the hydraulic ratings outlined earlier govern performance once the drive turns.
