The PVV5-1X/193LA15UMC pump belongs to the PV Fixed Displacement Pumps series manufactured by Bosch Rexroth for hydraulic automation where a constant delivery rate is required. Its displacement of 193.4 cm³ per revolution supplies a uniform volume of fluid to downstream circuits, and the anti-clockwise rotation direction matches power-train arrangements that drive from the opposite side. A cylindrical drive shaft in Version A form eases coupling to electric motors or gearboxes while keeping torsional deflection low. Continuous operation is permitted at 175 bar so the pump can sustain medium-pressure actuator groups without derating. The rotor may turn up to 1800 rpm for peak demand yet must not drop below 600 rpm to maintain internal lubrication and cooling. When driven at 1500 rpm, the pump delivers 285 L/min, enabling large cylinder banks to move at design speed. A mass of 34 kg defines the required support structure and influences vibration isolation measures.
The hydraulic circuit must employ HLP mineral oil conforming to DIN 51524-2 because the sealing system and bearing clearances were selected for that fluid type. Oil cleanliness has to reach ISO 4406 class 20/18/15 to avoid abrasive wear in the gear set and housing bores. During start-up, the shaft can transmit up to 610 Nm, so couplings and keys need matching strength. Acceptable fluid temperatures span from −10 °C to +70 °C, establishing the limits for heater or cooler selection. Pressure leaves the housing through an SAE 1 1/2-inch port located on the bottom at 180°, which guides pipe routing toward the machine frame. Suction enters through a larger SAE 3-inch connection that minimizes inlet velocity and prevents cavitation. These interface sizes shorten installation time and keep line losses low.
