PVV41-1X/082-018RA15UUMC

The PVV41-1X/082-018RA15UUMC pump belongs to the PV Fixed Displacement Pumps series from Bosch Rexroth and serves as a constant-flow source in hydraulic automation circuits. It is configured for a clockwise direction of rotation, allowing designers to pair it with power units that drive the shaft in a matching orientation. A maximum speed of 1800 min-1 defines the upper limit for input rpm so the pump can sustain rated output without cavitation. The cylindrical shaft end supports direct coupling to standard drive elements, while an SAE-C mounting flange aligns the housing to common industrial motors. On the flange side, the pump delivers 81.6 cm³ per revolution; this high displacement supports circuits that need significant oil volume per turn. A corresponding maximum flow of 120 l/min at 1500 rpm indicates the throughput available for that side. The continuous pressure rating of 175 bar on the flange side sets the permissible system pressure for long-term duty, and an SAE 1 ¼ in pressure port provides the connection size to route that flow. Overall mass is 34 kg, which influences mounting supports and handling during installation.

On the cover side, the displacement is 18.0 cm³ per revolution, giving a smaller dedicated flow path for auxiliary hydraulic functions. At 1500 rpm this section produces a maximum flow of 26 l/min, supplying moderate volume where precise actuation is required. Its continuous pressure limit is 210 bar, allowing the cover side to operate at a higher working pressure than the flange section. An SAE ¾ in pressure port is provided to attach pressure lines of suitable size, while a common SAE 3 in suction connection feeds both stages to minimize inlet losses. NBR sealing material is used throughout the pump to maintain fluid containment when exposed to standard hydraulic oils. The cleanliness class of ISO 4406 20/18/15 defines the particle contamination level that must be maintained in the fluid to protect internal surfaces and keep clearances within design limits.
