The 2520V17A5 1DC22R pump belongs to the V Series Vane Pumps and is produced by Vickers for hydraulic automation circuits that require split-flow capability. It delivers 18 cm³ per revolution on the cover end, establishing the stroke volume for low-flow high-pressure branches. Displacement on the shaft end is 55 cm³ per revolution so the second section can feed higher-flow functions from the same drive. A rated capacity of 5 gpm on the cover end defines the steady output available to small actuators, while the shaft end supplies 17 gpm to satisfy larger consumers. Maximum cover-end pressure is 207 bar, letting that side operate cylinders that demand elevated force. The shaft end tolerates up to 172 bar, matching its larger displacement with a moderate pressure limit to balance power input. Together these limits ensure each section works within vane loading constraints without overheating.
Clockwise rotation viewed from the shaft end sets the orientation of the inlet and outlets during assembly. A minimum speed of 600 rpm keeps internal lubrication reliable, and permitted speed extends to 1800 rpm to support variable-speed drives. Input shaft torque may reach 250 Nm, providing the mechanical effort required to achieve rated pressure without coupling slip. Inlet pressure must not exceed 1.4 bar so shaft seals remain intact under suction conditions. Flange mounting aligns the housing accurately with the prime mover and carries radial loads. Fluid discharge uses an SAE four-bolt flange, offering a rigid interface that resists leakage. Outlet 1 sits 90° clockwise from the inlet and outlet 2 sits 45° clockwise, allowing hoses to clear adjacent components in compact power units.
