The PVV41-1X/113-027RA15DDMC pump belongs to the PV Fixed Displacement Pumps series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It is built to deliver constant volume transfer where speed and pressure are tightly defined. Clockwise shaft rotation allows direct coupling to standard right-hand prime movers. The cover side displacement of 27.4 cm³ per revolution provides a small, precise flow channel, while the flange side displacement of 112.7 cm³ per revolution supplies larger volume when needed in the same assembly. At 1500 rpm those chambers yield flows of 39 L/min and 167 L/min respectively, letting designers balance pilot functions with main circuit supply. The unit operates from 600 rpm up to 1800 rpm so it can match slow idle conditions and higher demand cycles without stalling or over-speeding. Suction and pressure ports follow SAE patterns with UNC threads to simplify hose selection and reduce fitting conversions.
Port orientation supports straightforward plumbing; the cover outlet is on the top, 45° to the right of the inlet, while the flange outlet sits directly on top at 0°, allowing two hoses to rise vertically in compact manifolds. A SAE C 127-2 mounting flange aligns the housing with common industrial drives and holds the rotating group concentric. Continuous service limits are 210 bar on the cover side and 175 bar on the flange side, giving separate circuits pressure ratings that fit auxiliary and main loads without an external relief change. Sealing surfaces use NBR material so the pump resists standard mineral oils and maintains elasticity in typical ambient ranges. The assembled unit weighs 34 kg, heavy enough for stable mounting yet still manageable for one-person handling with lifting aids. These characteristics make the pump a fixed-output source that can feed dual-pressure circuits while occupying minimal panel space.
