PVV4-1X/098RA15RMC

The PVV4-1X/098RA15RMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies constant hydraulic flow for automated machinery. Its displacement is 97.7 cm³ per revolution, so each shaft turn delivers a set oil volume for predictable actuator speed. When driven at 1500 rpm the pump outputs up to 141 l/min, supporting medium-size press or molding circuits. The minimum permitted speed is 600 rpm, allowing slower standby operation without loss of lubrication. A cylindrical type A drive shaft transfers torque from electric or diesel prime movers without key deformation. The unit mounts on a flange according to SAE J744, and the specific SAE-C 127-2 pattern aligns the housing with common power take-offs. Clockwise rotation is specified, so system designers must match motor direction to avoid cavitation. The assembled pump weighs 23 kg, which influences selection of support brackets and lifting methods.

Continuous operating pressure is limited to 175 bar to restrain bearing load and heat generation during extended duty cycles. The inlet side tolerates absolute pressures from 0.83 to 2.4 bar, a range that guards against vapor formation while permitting elevated tank positions. Pressure fluid must be HLP mineral oil according to DIN 51524-2 so that viscosity and additive pack match the internal clearances. The pressure port is on the right at a 90-degree angle to the inlet, simplifying rigid pipe runs in compact power units. That outlet uses an SAE 1 1/4 in connection, providing sufficient cross-section for the rated flow without excessive velocity. On the suction side an SAE 2 in port is provided, allowing low velocity entry of oil to minimize aeration. An NBR shaft seal resists standard mineral oil while withstanding normal temperature swings in industrial environments. These interface and fluid specifications complete the requirements needed for stable service in fixed-displacement hydraulic automation.
