The PVV1-1X/018RD pump is manufactured by Bosch Rexroth and belongs to the PV Fixed Displacement Pumps series, supplying hydraulic circuits with a constant volume for automated machinery. A clockwise direction of rotation matches drive trains arranged for right-hand shafts, while the fixed nominal displacement of 18 cm³ per revolution defines the exact volume transferred each cycle. When driven at 1500 rpm the unit delivers 26 l/min, giving steady flow for medium-sized actuators. A minimum shaft speed of 600 min⁻¹ is required to keep internal bearings lubricated, and operation is allowed up to 1800 min⁻¹ for higher throughput demands. The pump is designed for HLP mineral oil according to DIN 51524-2, so seals and sliding surfaces receive the intended additive package. Acceptable viscosity spans from 13 mm²/s to 860 mm²/s, enabling cold starts and hot running without loss of film strength. A large SAE 1 1/2 in suction port limits inlet velocity and reduces cavitation risk during high flow conditions.
The pump sustains a maximum continuous pressure of 210 bar, allowing it to drive cylinders and motors that need high force without overstressing internal parts. Absolute inlet pressure may range from 0.83 bar to 2.4 bar, so the unit can run with lightly flooded or boosted supply lines. Fluid temperature may reach +70 °C before thermal limits are exceeded, and the design tolerates down to −10 °C for reliable startup in cooler environments. An SAE 3/4 in pressure outlet standardizes connection to downstream piping and makes adaptation to common hose fittings straightforward. The assembly weighs 12 kg, permitting single-person handling during mounting or maintenance.
