The PVV4-1X/113RA15UMC pump is manufactured by Bosch Rexroth as part of the PV Fixed Displacement Pumps series for hydraulic automation, where it supplies a constant fluid flow to work circuits. The pump displaces 112.7 cm³ per revolution and provides 167 l/min when operated at 1500 rpm. It endures a continuous outlet pressure of 175 bar. Rotation is clockwise, so the drive shaft must be turned accordingly. The unit can run at speeds as low as 600 min⁻¹ to match variable engine outputs. An SAE-C mounting flange couples the housing to the prime mover. The pressure port is on the bottom at 180° and uses an SAE 1 1/4 in connection for discharge piping.
Hydraulic oil enters through an SAE 2 in suction connection, and an NBR seal contains the fluid to prevent external leakage and air ingress. The large suction port keeps inlet velocity low, which helps limit cavitation when the pump draws its maximum flow. Permitted fluid temperature extends from -10 °C to +70 °C, so reservoir heaters or coolers must keep bulk oil within this window for consistent viscosity. Acceptable viscosity spans from 13 to 860 mm²/s, allowing the use of thin startup fluids and heavier operating grades without harming lubrication. The pump weighs 23 kg, which influences support bracket sizing and handling during maintenance.
