The V10 2P1P 1D20 unit belongs to the Square Vane Pumps series and is manufactured by Vickers for low-flow hydraulic automation. Its design number 20 identifies the internal geometry selected for this model. A displacement of 6.6 cm³ per revolution sets the volume of oil moved on each shaft turn, while the rated capacity of 2 US gpm at 1200 rpm and 100 psi shows expected output in light-duty circuits. The model operates up to a maximum pressure of 172 bar, enabling it to supply actuators that need moderate system pressure. A speed ceiling of 4500 rpm supports compact power units that run at elevated motor speeds. Right-hand shaft rotation defines the correct orientation relative to the drive, and a permitted inlet supercharge pressure of 0.7 bar helps prevent cavitation when the reservoir is mounted below the pump.
Inlet connection is a 1 in NPT port, simplifying pipework on typical industrial tanks, and the inlet vacuum limit of 5 in Hg restricts suction losses to maintain full charge at high speed. The shaft measures 19.05 mm in diameter and is cut for a 4.75 mm key, giving a standard drive interface for electric motors and couplings. Outlet flow leaves the housing 90° clockwise from the inlet, a fixed orientation that assists in rigid line routing inside compact machinery frames. A pilot diameter of 82.55 mm centers the body in mounting bores to control radial run-out. Together, these dimensional features align the pump quickly during installation, keep hydraulic performance stable under continuous duty, and reduce field service time.
