The PVV21-1X/068-027RJ15DDMB pump is produced by Bosch Rexroth within the PV Fixed Displacement Pumps series. Designed for hydraulic automation, it delivers two fixed displacements: 67.5 cm³ per revolution at the flange end and 27.4 cm³ per revolution at the cover end, enabling parallel circuits from a single drive. Continuous operation is supported between 600 rpm and 1800 rpm when the inlet pressure is 1 bar, while clockwise rotation matches common industrial drive directions. The cover section tolerates up to 210 bar, making it suitable for medium-pressure work circuits, and the pump relies on HLP mineral oil according to DIN 51524-2 for lubrication and power transmission. Installation is handled through an SAE-B (101-2) mounting flange, and the complete assembly weighs 20 kg so lifting equipment is usually not required during service.
Fluid cleanliness must reach ISO 4406 class 20/18/15 to maintain reliable bearing life and valve fit. The flange section permits a continuous pressure of 175 bar and delivers flow through an SAE 1 in pressure port, whereas the cover side uses an SAE 3⁄4 in outlet to separate the two circuits. Suction oil is drawn through an SAE 2 1⁄2 in connection that minimizes inlet velocity and reduces cavitation risk. An NBR seal set contains the fluid and resists typical mineral-oil additives found in industrial systems. These interface dimensions and material choices allow the PVV21-1X/068-027RJ15DDMB to integrate into reservoirs and manifolds that follow standard SAE patterns while protecting internal components at the specified cleanliness level.
