PVV5-1X/154RA15DVC

The PVV5-1X/154RA15DVC pump is built by Bosch Rexroth and belongs to the PV Fixed Displacement Pumps series. It delivers constant volume for hydraulic automation circuits that require predictable flow. A displacement of 153.5 cm³ per revolution defines the amount of fluid moved each shaft turn, supporting accurate actuator speed control. When driven at 1500 rpm, the pump provides a maximum flow of 223 l/min, giving designers a clear value for sizing return and cooling lines. It can run safely up to 1800 rpm, enabling higher flow in systems with variable-speed drives, while a minimum speed of 600 rpm maintains internal lubrication during slow-running cycles. Clockwise rotation establishes alignment with engine or motor outputs that share the same direction, and a continuous pressure limit of 175 bar matches common industrial hydraulic loads. The inlet must stay above an absolute pressure of 0.83 bar to prevent cavitation, and the assembly has a mass of 34 kg, which influences handling and mounting hardware selection.

Flange mounting according to SAE J744 simplifies integration onto power units, and the specific SAE-C (127-2) mounting flange ensures compatibility with standard prime movers. A SAE 1 ½-inch pressure connection provides a uniform interface for the high-pressure line, whereas a SAE 3-inch suction port accommodates the larger flow area required on the low-pressure side. Positioning the pressure port on the top at 0° relative to the inlet aids straightforward tube routing and reduces trapped air. All hydraulic ports use SAE flanges fastened with UNC screws, allowing repeatable joint torque without metric hardware. An FKM seal set resists common hydraulic oils and elevated temperatures, improving service life in continuous duty. These features collectively let the pump attach quickly, maintain tight sealing, and fit within standardized layouts used across mobile and industrial hydraulic equipment.
