The PVV2-1X/055R fixed displacement pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies constant fluid volume for hydraulic automation. Its displacement is 55.2 cm³ per revolution, so every shaft turn moves a predictable volume into the system. When driven at 1500 rpm the unit reaches a flow of 80 l/min, supporting medium-capacity circuits that need steady delivery. Continuous outlet pressure is limited to 175 bar to match standard manifold ratings, and the allowable absolute inlet pressure spans 0.83 to 2.4 bar to protect against cavitation. The pump turns clockwise and can run between 600 and 1800 min⁻¹ at a 1 bar inlet, permitting speed variation with common prime movers. Fluid enters through a SAE 1 ½ in suction port and leaves through a SAE 1 in pressure port, sizes chosen to control velocity and reduce line losses.
Fluid temperature must stay between −10 °C and +70 °C, a range that aligns with typical mineral hydraulic oils, while viscosity can vary from 13 to 860 mm²/s so different grades remain acceptable during cold starts or heavy duty. The cleanliness requirement of ISO 4406 20/18/15 defines the filtration level needed to limit particulate wear inside the pumping elements. A mass of 14.8 kg allows one person to position the pump during maintenance or initial assembly. Together these limits guide reservoir heating, cooling, filtering, and handling practices to keep the PVV2-1X/055R operating within specification.
