The V2010 1F9S5S 1AD12L 167 pump belongs to the Square Vane Pumps series and is produced by Vickers for hydraulic automation where compact flow sharing is needed. It secures to a power source with a 2-bolt SAE B flange mounting type, and the inlet uses an SAE 4-bolt flange with a 1.50 in flange diameter so the suction line remains rigid under vacuum. Cover-end displacement is 16.4 cm³/r (1.00 in³/r), supplying precise metered flow for auxiliary circuits, while a cover-end rated capacity of 5 US gpm at 1200 rpm and 100 psi defines its baseline output. The cover-end outlet thread is .750-16 UNF-2B, giving compatibility with common hydraulic fittings. Counter-clockwise rotation viewed from the shaft end enables coupling to engines spinning in that direction, and a 0.1875 in shaft key width locks the drive element against torsional loads.
On the shaft end, displacement rises to 29.7 cm³/r (1.81 in³/r), letting the pump deliver greater volume from the same input speed. At 1200 rpm and 100 psi this side outputs 9 US gpm, matching medium-duty actuator flows, and its outlet carries a 1.0625-12 UN-2B thread for larger pressure lines. Both ends tolerate a maximum operating pressure of 172 bar (2500 psi), allowing the unit to work in high-pressure manifolds without derating. Safe prime-mover limits are set by maximum speeds of 3200 r/min for the cover end and 2800 r/min for the shaft end, guarding vane integrity during rapid cycles. A 0.875 in shaft major diameter provides the torsional strength required to transmit power at these pressure and speed ratings.
