Low Pressure Variable Vane Pump (double pump)

Product Description

It is combined by two VP series vane pump which share common drive shaft. The biggest feature of VP Double pump is that could generate two flow of different pressure by using one electric motor of the pumps. The flexible design of system provides best choice in high efficiency circuit for system design engineer.
Doubel variable vane pump drive by one motor, which reduce assembly space.

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) when temperatuers approaching 40 degrees. Above 70bar, using oil in viscosity of 50-70cSt(ISO VG32) when temperatuers approaching 40 degrees.
Pressure of oil drain pipe: please directly connect pipe below oil level in the tank, and maintain the matching pipe below 0.3bar
Working oil temperatuer: 15-60 ºC for constant rotation
Concentric mate: Eccentricity erro between pump spindle and motor shaft is 0.05mm, and angular deviation is 1°
Inlet pressure: Pressure of suction port is between -0.3bar~0.3bar
Adjustment of displacement: Loose adjusting nut, and then rotate adjusting screw, turning right to reduce the flow.
Adjustment of pressure: Turning the pressure adjusting screw to right to decrease the output pressure. Vice verse.
Max. peak: ≤140 bar
