The 02-466369 piston pump is produced by Vickers within the Piston Pumps series and supplies hydraulic power for automated machinery that requires controlled flow and pressure. The fixed displacement of 41 cm³ per revolution sets a predictable output volume per shaft turn. A 22.2 mm keyed shaft in accordance with SAE J744-22-1 transfers drive torque from the prime mover, and the pump tolerates up to 135 Nm at maximum displacement to handle heavy duty cycles. It rotates left-handed so users must arrange the drive train accordingly. System pressure can rise to 210 bar, while a compensator limits working pressure to 72.39 bar to protect downstream components. Acceptable oil viscosity ranges from 16 cSt to 40 cSt, so fluid selection and temperature control must keep the oil within this window for efficient operation.
Installation details include a two-bolt B front mount that aligns the housing to standard motor flanges. Inlet flow enters through a 1.875-12 UN-2B SAE O-ring suction port, and pressurized oil exits via a 1.3125-12 UN-2B SAE O-ring pressure port, while excess leakage drains through a 0.875-14 UNF-2B SAE O-ring case port. The internal case is limited to 0.7 bar, so drain plumbing must remain unrestricted. ISO cleanliness code 21/18/13 is required to prevent wear of the rotating group. Overall length is 10.34 in and weight is 42 lb, factors that influence mounting brackets and hoisting equipment during service.
