The 02-341964 piston pump belongs to the Piston Pumps series from Vickers and supplies hydraulic flow in automated machinery. It delivers 41 cm³ of displacement per revolution so circuit designers can calculate required flow at a rated speed of 2400 rpm. A right-hand clockwise shaft rotation matches common engine and motor drives, and the 25.4 mm (1.00 in) input shaft diameter fits standard couplings. Maximum input torque is 215 Nm, enabling the pump to transmit full displacement without slip. The housing is made of cast iron to withstand continuous load, while a 2-bolt B front mounting pattern simplifies attachment to power units. Fluorocarbon rubber shaft seals resist hydraulic oil and temperature, maintaining internal pressure integrity.
Peak system pressure reaches 210 bar, and the compensator is factory set to 210.3 bar to limit outlet pressure automatically. The inlet side requires only 2 bar, allowing operation with modest tank elevation. Pressure fluid exits through a 1.3125-12 UN-2B port, and supply oil enters through a 1.875-12 UN-2B suction connection; a separate .875-14 UNF-2B drain port on the top face directs case leakage back to the reservoir. Required fluid cleanliness is 21/18/13 to preserve internal surfaces, and there are no diagnostic pressure ports, so external gauges must be used for monitoring. These characteristics permit straightforward installation while maintaining durability and stable flow under compensated control.
