Hydraulic Pump-Variable Displacement Vane Pump (VP-12-FA2)

Specialty:
With Automatic high speed flow and compensation function   under the setting pressure.Comparing with fixed displacement vane pump,it has lower consumption and heat radiation;
Stable and noiseless in operation,especially suitable for machine tool and accord to requirements of housed activities.
It contains mechanical pressure adjustment;For an arbitrary choice

Instructions:
Rotation Direction: Clockwise direction is standard while counterclockwise direction is a special style
Hydraulic oil: below 70bar,using oil in viscosity of 30-50cSt(ISO VG32)
Pressure of Oil drain pipe: Please directly connect pipe below surface of oil,and maintain the matching pipe below 0.3bar
Working oil temperature:15-60ºC for constant rotation
Concentric Mate:Eccentricity error between pump spindle and motor shaft is 0.05mm,and angular misalignment is 1°
Inlet pressure:Pressure of suction port between -0.3bar~0.3bar
Adjustment of displacement:Loose adjusting nut,and then rotate adjusting screw, turning right to decrease the flow
Adjustment of pressure:Turning the pressure adjusting screw to right to decrease the output pressure.Vice verse.
Maximum peak:≤140bar
New machine rotation: Start the motor over and over again at no pressure condition, to eliminate air in pump and oil suction pipe,and guarantee no air in the pipe.The new machine could rotate for 10 minutes under the condition of no load.
