The Bosch Rexroth AZPB-32-4.0RQR12KB-S0022 (R979107387) is an external gear pump that excels in converting mechanical energy into hydraulic energy with high efficiency, which is achieved through pressure-dependent gap sealing and precision manufacturing technology. This unit is designed with a straight shaft conforming to SAE J744 standards and a bolt flange that adheres to SAE J518 AA specifications. It features thread UNB and SAE O-Ring line connections for versatile integration into various hydraulic systems. The pump's robust construction includes slide bearings capable of handling high loads, ensuring consistent performance and a long service life. The rear cover of the pump is standard, and it operates at a maximum rotational speed as specified by the product group ID. With a geometric displacement size of 32 cm³/rev, this pump can handle a substantial volume of fluid with each rotation. Sealing materials used in the Bosch Rexroth AZPB-32-4.0RQR12KB-S0022 are NBR for the housing seal, with an FKM shaft seal offering corrosion resistance and durability under diverse operating conditions. The special version of this pump may include deviations from standard catalogue specifications, which can be referenced in the accompanying drawing for precise details. This model boasts an aluminum housing that contributes to its relatively lightweight design of 5.1 kg while maintaining strength and resistance to wear. The maximum intermittent pressure that the pump can withstand ensures reliable operation during peak demands. With its clockwise direction of rotation and bearing diameter of 22 mm, this external gear unit functions primarily as a pump within hydraulic systems. The Bosch Rexroth AZPB-32-4.0RQR12KB-S0022 maintains a standard noise level during operation, making it suitable for environments where noise control is important. Its maximum flow capacity reaches up to 40 l/min, making it an effective solution for applications requiring consistent fluid transfer at high efficiencies.
