The PVV4-1X/098LA15UMC pump is built by Bosch Rexroth within the PV Fixed Displacement Pumps series. It supplies a constant volume of hydraulic fluid for automated machinery where predictable flow is required. Its displacement is 97.7 cm³ per revolution, delivering a fixed volume that simplifies circuit design. Running at 1500 rpm, the unit supplies 141 l/min, providing adequate flow for medium-size actuators. A maximum continuous pressure rating of 175 bar enables the pump to sustain working loads in industrial presses and molding equipment. The shaft can operate from 600 min⁻¹ upward, so low-speed drives maintain lubrication without stalling. Anti-clockwise rotation matches prime movers configured for left-hand drive arrangements. A flange mount that follows SAE J744 supports direct coupling to standard electric motors, and the pump weighs 23 kg, allowing installation by a single technician with normal handling tools.
For stable suction conditions, the pump must receive an inlet pressure above 0.83 bar absolute, while it tolerates up to 2.4 bar absolute to prevent seal overload when the reservoir is elevated. The housing interfaces to a SAE-C 127-2 mounting flange, providing alignment with common transmission pads. HLP mineral oil defined in DIN 51524-2 is specified as the pressure fluid, ensuring compatibility with the internal elastomers and clearances. System piping attaches to a SAE 1 1/4-inch pressure port located at the bottom at 180°, so gravity helps vent trapped air during start-up. A SAE 2-inch suction port admits fluid with low velocity to limit cavitation. These connection details and fluid guidelines let the pump integrate cleanly into fixed industrial hydraulic power units.
