The V10F 1S7T 11A5H 20 pump is manufactured by Vickers and belongs to the Square Vane Pumps series, providing controlled oil delivery for hydraulic automation tasks. It delivers a regulated flow of 19 L/min (5 US gpm) and offers a displacement of 22.8 cm³ per revolution (1.39 in³ /rev) to match medium-duty actuator demands. Under nominal conditions the unit reaches a rated capacity of 27 L/min (7 US gpm), while its maximum drive speed of 2800 rpm defines the upper operating limit for connected electric or combustion motors. Clockwise shaft rotation is fixed as right-hand, so system plumbing must follow that direction. Power is transmitted through a 16/32 DP spline with 9 teeth, and installation is completed with a 2-bolt flange that aligns the housing securely to mounting plates.
Hydraulic connections are arranged for straightforward circuit layout: the inlet port is threaded 1-5/16-12 UN-2B (SAE) for low-pressure suction, the outlet port uses 3/4-16 UNF-2B (SAE) for pressure delivery, and a matching 3/4-16 UNF-2B (SAE) pressure port permits instrumentation or auxiliary lines. Return flow is routed to a 7/8-14 UNF-2B (SAE) tank port that leads back to the reservoir. The pump withstands continuous service up to 138 bar (2000 psi), and an internal relief valve is preset to open at 140 bar (2000 psi) to protect downstream components from overload.
