The PVV52-1X/193-068RA15DDMC unit belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and supplies a constant volume of hydraulic fluid for automated actuators and tooling. SAE ports secured with UNC screws simplify piping and bolt attachment, while a SAE-C (127-2) mounting flange aligns the housing with standard drive pads. The cover section displaces 67.5 cm³ per revolution, and its outlet is on the top, positioned 45° to the right of the inlet to streamline line routing in stacked assemblies. Continuous pressure on the cover side is limited to 140 bar so circuit designers can size relief valves appropriately. When driven at 1 500 min⁻¹, the cover delivers a maximum flow of 100 L/min, supporting moderate-duty cylinders or motors. Stable operation begins at 600 min⁻¹, which allows slow-running prime movers to engage the hydraulic system without loss of lubrication.
The flange section processes a larger 193.4 cm³ of fluid per revolution and sends flow through a port located at the top, directly in line with the inlet. It withstands 175 bar of continuous pressure, and can supply up to 285 L/min at 1 500 min⁻¹ for high-demand work functions. Overall shaft speed may rise to 1 800 min⁻¹ when inlet pressure is 1 bar, extending the usable flow range of the device. Rotation is clockwise, matching common diesel engine outputs used on mobile machinery. NBR sealing elements isolate the internal passages from external contaminants and retain oil under thermal cycling. The complete assembly weighs 46 kg, a consideration for bracket design and service handling in confined power-train compartments.
