4535V60A25 1BB22R

The 4535V60A25 1BB22R pump is produced by Vickers as part of the V Series Vane Pumps series. Intended to move hydraulic oil in automated machinery, it uses the vane principle for smooth delivery and low pulsation. A shaft end displacement of 193 cm³ per revolution defines how much fluid the primary cartridge moves during each shaft rotation, supporting large flow demands. The cover end displacement is 81 cm³ per revolution, adding supplemental flow for circuits that require dual volume outputs. Clockwise rotation when viewed from the shaft end sets the correct drive orientation for engines or electric motors that match this turning direction. The unit operates up to 1800 rpm, providing adequate speed range for common industrial prime movers without exceeding internal load limits. A flange mount secures the housing rigidly to power frames, and SAE four-bolt flanges simplify port plumbing in standard North American installations. The 5/16-inch square shaft key transmits torque from the drive without slippage under variable load.

Pressure and temperature ratings define continuous duty limits for this pump in hydraulic automation. A maximum continuous pressure of 172 bar allows the circuit to maintain high working forces while preserving seal life. The inlet side tolerates up to 1.4 bar absolute pressure, so flooded suction systems can be used without risk of bearing overload, whereas a minimum inlet pressure of –0.17 bar protects against excessive vacuum that might cause cavitation. Fluid temperatures may reach 99 °C, allowing operation with hot oils common in industrial environments. The internal ring design supports 60 gpm on outlet one and 25 gpm on outlet two, offering separate flow paths for actuators that need different volumes. Both outlets are located 90° counter-clockwise from the inlet, which helps designers orient piping runs inside confined power units. These characteristics enable consistent flow, efficient cooling, and reliable operation within multipressure hydraulic circuits.
