The PP20/G2022/10/RV/H3/L0 power pack is built by Bosch Rexroth for the Rexroth Power Packs series and supplies pressurized oil to cylinders and valves in hydraulic automation systems. A pump displacement of 1.37 in³ per revolution meters fluid precisely, and at the rated motor speed of 1750 rpm the unit delivers a maximum flow of 10.0 GPM (37.85 L/min) for consistent actuator response. System pressure can be adjusted up to 1450 psi (100 bar) to match load demands. Drive energy comes from a 10 hp (7.4 kW) motor configured for 3-phase operation, so the pack connects directly to 230 or 460 VAC mains at 60 Hz without additional transformers. These electrical and hydraulic parameters give the assembly balanced performance for moderate-duty industrial machinery.
An air/oil heat exchanger identified by part number R978808140 in the H3 configuration removes excess heat from the circulating fluid to maintain stable viscosity. The motor housing is a totally enclosed fan-cooled design that shields windings from airborne oil mist during continuous service. A steel reservoir holds 20 gal (76.0 L) of hydraulic fluid and includes a ‑8 SAE drain port to simplify scheduled oil changes. Return flow passes through a 20 µm absolute filter to capture particles before the fluid re-enters the tank, helping protect valves and actuators. A factory-installed relief valve and pressure gauge safeguard the circuit against over-pressure and provide immediate visual feedback. Together these features control temperature, cleanliness, and pressure so the power pack can run reliably in automated production lines.
