V10 1P3P 12C20

The V10 1P3P 12C20 pump is supplied by Vickers as part of the Square Vane Pumps series and is intended to circulate hydraulic oil in moderate power circuits. It displaces 9.8 cm³ per revolution, so a fixed volume of fluid moves with each shaft turn to maintain repeatable flow. A rated capacity of 3 US gpm at 1200 rpm and 100 psi frames expected delivery in low-pressure test conditions, while the maximum operating pressure of 172 bar (2500 psi) defines the highest load the housing and internal vanes can withstand. The unit survives speeds up to 4000 rpm, allowing it to pair with faster electric motors when compact tanks must be filled quickly. Right-hand clockwise rotation matches common engine drive directions and prevents port crossover errors. A 2-bolt SAE A flange supports direct face mounting to standard pump pads, reducing alignment tasks. Fluid enters through a 1 in NPT inlet and exits through a 1/2 in NPT outlet, sizes selected for balanced velocity and minimal line losses.

A positive inlet pressure should not exceed 0.7 bar (10 psi), ensuring shaft seals are not overloaded, while allowable inlet vacuum is limited to 5 in Hg to stop cavitation during high-speed draws. The outlet is inline with the inlet, so hoses can run parallel along the same plane and shorten installation time inside power units. Internally, the pumping element relies on sliding vanes to trap and move oil, a configuration chosen for quiet operation and good suction characteristics. A shaft extension length of 1.63 in provides enough engagement for flexible couplings without requiring spacers. Torque is transmitted through a 13-tooth spline; the major diameter measures 0.873 in, the pitch is 16/32 DP, and these values match common drive splines on small industrial motors. Together, these drive details secure the rotor under full load without fretting. With the stated inlet limits and drive geometry, the pump integrates cleanly into hydraulic automation skids that demand steady flow and compact packaging.
