V10 1P7P 38B20 LH

The V10 1P7P 38B20 LH pump belongs to the Square Vane Pumps series manufactured by Vickers for fixed-displacement hydraulic circuits. The unit delivers 22.8 cm³ of fluid per revolution so each shaft turn moves a predictable volume for repeatable actuator motion. At 1200 rpm and 100 psi it supplies a rated capacity of 7 US gpm, providing a reference point for sizing auxiliary components. The maximum operating pressure of 138 bar (2000 psi) defines the highest load the housing and rotor can withstand during continuous duty. A top speed limit of 2800 rpm lets designers balance flow demand with acceptable tip velocity. Viewed from the shaft end the rotation is left-hand, or counter-clockwise, and on the cover end the outlet is positioned 90 degrees counter-clockwise from the inlet, simplifying hose routing in compact power units.

Fluid enters the pump through a 1 in NPT inlet port, a common thread that mates directly with standard schedule 80 pipe fittings. The inlet side may be pressurized up to 0.7 bar (10 psi), while a permissible vacuum of 5 in Hg guards against cavitation during tank-top mounting. A two-bolt flange secures the housing to the motor face and keeps shaft alignment stable under dynamic loading. Torque is transmitted through a splined shaft whose minor diameter measures 0.590 in, and the form follows No. 38 with 11 teeth at 16/32 DP and a 30 degree pressure angle, allowing drop-in coupling with matched drive hubs. These mechanical, hydraulic, and connection limits complete the specification set and define the pump’s role in automation where consistent flow and straightforward service are required.
