The PVV41-1X/122-040RA15DDMC belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and is configured for hydraulic automation circuits that require a constant delivery volume. It operates with clockwise shaft rotation, so drive trains must follow that direction to maintain correct inlet and outlet orientation. The pump is filled with HLP mineral oil according to DIN 51524-2, a fluid choice that supports wear protection and thermal stability. Cleanliness must be kept to ISO 4406 20/18/15 to prevent premature wear in the tight running clearances. A SAE-C mounting flange provides a standardized interface to electric motors or combustion-engine bell housings, while a large SAE 3 in suction port ensures low inlet velocity and reduced cavitation risk. The cover stage delivers 39.5 cm³ per revolution and produces 59 L/min at 1500 rpm, with continuous cover pressure limited to 160 bar for long service life. Its pressure line exits through a SAE 3⁄4 in connection located on the top face, simplifying rigid pipe routing when the pump is mounted horizontally.
The flange stage enlarges system capacity by supplying 121.6 cm³ per revolution and 177 L/min at 1500 rpm, allowing a single pump unit to feed multiple actuators or large-displacement cylinders. This section can sustain 175 bar continuously, offering a higher working limit than the cover side for circuits that demand elevated force. Discharge oil leaves the flange stage through a top-oriented SAE 1 1⁄4 in port, so both outlets reside at 0° and can be manifolded together without complex elbows. Positioning the pressure ports upward also promotes natural air bleeding during commissioning. By combining two fixed-volume elements in one housing, the pump supports dual-flow applications while occupying minimal space, and each stage’s dedicated connection sizes let designers match line diameters to the respective flow rates.
