The PPV20-1-5-RV-1-0-0-0 hydraulic power pack belongs to the Rexroth Power Packs series and is manufactured by Bosch Rexroth for use in automated fluid power systems. Its axial piston variable pump allows adjustable flow so actuators can be driven at changing speeds and loads. A close-coupled motor-pump mounting keeps alignment precise and eliminates shaft coupling hardware. High-pressure output leaves the unit through an SAE-12 pressure port with 1-1/16-12 UN threads, while internal leakage is routed back through an SAE-8 case drain port to prevent housing pressurization. The assembly is rated for a maximum system pressure of 3000 psi (200 bar), and an integrated system relief valve opens when this limit is reached to protect circuit components.
A three-phase motor supplies the pumping energy; it operates on either 230 VAC or 460 VAC and delivers 5 hp (3.7 kW) at 1750 rpm for steady industrial duty. The frame size 184 defines the motor’s mounting footprint, and a service factor of 1.15 permits short overload periods without overheating. Hydraulic fluid is stored in a 20 gal steel reservoir that resists deformation and dissipates heat to maintain oil viscosity. Return flow enters the tank through an SAE-12 return port, and a 20 µm absolute filter in this line removes particulate contamination before the oil re-enters the reservoir.
