The PVV41-1X/122-036RA15DDMC pump is produced by Bosch Rexroth for the PV Fixed Displacement Pumps series and supplies constant flow for hydraulic automation. It turns clockwise, so the drive shaft and coupling must be arranged for that direction. Two pumping elements share one housing: the cover side displaces 36.4 cm³ per revolution, while the flange side displaces 121.6 cm³ per revolution, allowing independent circuits with different flow needs. Continuous working limits reach 210 bar on the cover outlet and 175 bar on the flange outlet, so each port can be matched to its load. Shaft speed may run up to 1800 min⁻¹, giving flexibility when paired with diesel engines or electric motors. A standard SAE-C mounting flange defined in SAE J744 simplifies attachment to common prime movers. Driven at 1500 rpm, the cover section provides 53 l/min for auxiliary functions.
Under the same 1500 rpm condition, the flange section supplies 177 l/min to high-volume branches. Pressure fluid leaves through a 3/4-inch SAE port on the cover side and a 1 1/4-inch SAE port on the flange side; both ports sit on the top of the housing at 0°, which keeps outlet hoses clear of the mounting surface. A single 3-inch SAE suction connection feeds both stages to minimize inlet losses. NBR seals are installed to contain mineral oil under varying temperatures without swelling or cracking. Total weight is 34 kg, so support brackets must bear that load while still enabling manual handling with standard shop cranes. These interface details integrate the pump into multi-circuit hydraulic equipment without additional adapters.
