The PVV4-1X/098RA15DMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies a fixed volume of fluid for hydraulic automation loops. Its displacement is 97.7 cm³ per revolution, so every shaft turn moves a consistent volume into the pressure line. The unit tolerates continuous pressures up to 175 bar, allowing it to drive medium-duty actuators without flow loss. At 1,500 rpm the pump can deliver 141 L/min, while permissible shaft speed spans from 600 rpm to a ceiling of 1,800 rpm when the inlet is held at 1 bar. A SAE-C (127-2) mounting flange aligns the housing with standard power takeoff pads, and total mass is 23 kg for straightforward handling. Oil entering the pump must meet ISO 4406 class 20/18/15 cleanliness to prevent wear.
For temperature-controlled circuits the pump accepts hydraulic oil from −10 °C to +70 °C, ensuring viscosity stability within the machine envelope. Fluid viscosity may range from 13 mm²/s to 860 mm²/s, giving installers flexibility in selecting seasonal or synthetic blends. Inlet conditions are defined by an absolute minimum of 0.83 bar and a maximum of 2.4 bar, so reservoir layout must avoid excessive vacuum or overpressure. Pressure discharge connects through an SAE 1 ¼ in port, while suction flow enters through a larger SAE 2 in port to limit entrance velocity. These connection sizes simplify hose selection and reduce cavitation risk at the rated flow. Together the stated temperature, viscosity, and inlet limits allow the pump to maintain stable volumetric efficiency across varied industrial duty cycles.
