The 02-466364 piston pump is manufactured by Vickers for the Piston Pumps series. It supplies regulated hydraulic flow for automated presses, conveyors, and handling units. A displacement of 45.1 cm³ per revolution determines the volume delivered each shaft turn, and a peak pressure rating of 186 bar allows the unit to drive high-force actuators. The pump can absorb up to 28.3 kW of input power, so motor sizing must match this demand. Right-hand shaft rotation aligns the coupling with standard clockwise prime movers, while a fluorocarbon shaft seal blocks external leakage during thermal cycling. The suction port is threaded 1.875-12 UN-2B with an SAE O-Ring seat to draw oil from the reservoir, and the pressure port uses a 1.3125-12 UN-2B connection for high-pressure discharge. A pressure compensator preset at 72.39 bar trims output flow once system pressure reaches that level to reduce energy waste.
For internal leakage return, a 0.875-14 UNF-2B drain port routes case oil directly to tank. The housing is limited to a case pressure of 0.35 bar, so unrestricted drain plumbing is required to protect the shaft seal. Operating noise is measured at 71 dB, helping machines meet shop-floor sound limits without additional acoustic treatment. The pump body measures 10.4 in in length, 7.77 in in width, and 7.14 in in height, creating a compact footprint for crowded power units. Its weight of 45.4 lb permits single-person handling during installation. The compact envelope and manageable weight simplify installation alongside other automated equipment.
