The Bosch Rexroth PVV21-1X/040-018RJ15DDMB (R978913149) is a high-quality hydraulic vane pump known for its robust construction and reliable performance. This pump features a constant displacement design, ensuring consistent flow for hydraulic systems. Its innovative construction includes a rotor running in a stator ring, which is integrated into the tooth profile of the drive shaft. The rotor's slots hold the vanes that are pressed against the stator ring's internal surfaces by centrifugal force during rotation, creating efficient displacer chambers. This model benefits from a double-eccentric stator ring design that provides two pressure chambers opposite two suction chambers, facilitating hydraulic unloading of the shaft and only requiring it to transmit torque. This feature contributes to long bearing life and reduces wear on the vanes as they move through the suction range, enhancing overall efficiency and service life. The pump's easy maintenance is another key feature; its cover can be removed to access the pump insert, which includes the rotor, vane, stator ring, and control plates, without detaching the housing from its carrier. The PVV21-1X/040-018RJ15DDMB can be configured as a double pump by installing two pump kits on a single shaft, with one joint suction port and separate oil outlets for each kit. It is important to note that only different frame size kits can be paired; identical frame sizes are not compatible for double pump configurations. Additional characteristics include low operating noise and good efficiency with easy-to-service exchangeable cartridges. The pressure ports' positions are customizable, and it supports both clockwise and counterclockwise rotation with options for cylindrical or splined drive shafts. Its compact build makes it an excellent choice for systems where space is at a premium.
