The PVV4-1X/098RA15UVC is manufactured by Bosch Rexroth for the PV Fixed Displacement Pumps series and supplies a constant volume of hydraulic fluid for automated machinery. Its displacement is 97.7 cm³, defining the amount of oil moved each shaft revolution. At 1,500 rpm the pump delivers up to 141 l/min, meeting medium flow demands, while a permissible peak speed of 1,800 min⁻¹ at 1 bar absolute inlet pressure allows short-term output increases; operation must not drop below 600 min⁻¹ to prevent slip. Clockwise rotation coordinates with standard prime movers, and a SAE-C (127-2) mounting flange positions the unit on common bell housings. The housing weighs 23 kg, affecting handling requirements, and the pressure section withstands 175 bar to serve moderate-pressure circuits.
The pump handles fluid temperatures from −10 °C to +70 °C, enabling cold starts and sustained warm running, and an FKM shaft seal maintains integrity across this range. Oil viscosity must remain above 13 mm²/s so internal bearings receive adequate lubrication. Suction conditions are confined to 0.83–2.4 bar absolute; this window prevents cavitation while avoiding excessive inlet load. A SAE 2-inch suction port eases connection to low-restriction hoses, and the discharge side uses a SAE 1 1/4-inch pressure port that matches standard high-pressure lines. Together, these interface sizes, pressure limits, and temperature boundaries support reliable filling, stable discharge, and long service life in hydraulic automation systems.
