The PVV5-1X/193RA15UVC fixed displacement pump is part of the PV Fixed Displacement Pumps series manufactured by Bosch Rexroth. The unit supplies constant flow in hydraulic automation circuits that need stable volume delivery per revolution. It displaces 193.4 cm³ for every shaft rotation, enabling high output with steady efficiency. Clockwise rotation is specified, and the shaft must run at a minimum speed of 600 rpm to maintain lubrication. Continuous operating pressure can be held up to 175 bar, while the drive train can apply as much as 610 Nm of torque to the cylindrical-A shaft end without exceeding limits. The pump mounts on a flange conforming to SAE J744, and the housing matches the 127-2 SAE-C flange version for compatibility with common power-take-off pads.
At the inlet, absolute pressure must stay between 0.83 bar and 2.4 bar to prevent cavitation and seal damage. Hydraulic connections are SAE ports secured with fifteen UNC screws, with the suction side supplied through a SAE 3-inch port and discharge routed through a SAE 1 1/2-inch pressure port located on the bottom surface, 180° from the inlet. System cleanliness must reach ISO 4406 code 20/18/15 to protect internal gears and bearings. Installed mass is 34 kg, so lifting points or mechanical assistance are advised during assembly.
