CML Variable Displacement Vane Pump With Cooling Circulation Pump-zkx

The rotation of VCM-DF pump is clockwise when viewed from the shaft end.
The drain pipe is directly connected to the oil tand and the position must be below the level of oil.
Keep the suction pressure within 0.3 bar at the suction port.
Pressure adjusting screw is turned clockwise to increase pressure and counterclockwise to decrease pressure.

Flow adjusting screw is turned clockwise to increase flow and counterclockwise to decrease flow.
For proper alignment of pump and electric motor shaft, the eccentricity between them must be kept within 0.05mm and the eccentric angle error between them must be kept within 1.
When pressure is under 70 bar the viscosity of oil must be within 30-50 cSt, when pressure is over 70 bar the viscosity of oil must be within 50-70 cSt, at the temperature of 40C.
When first time operation, the pump should be at no-load state-on delivery side and be repeated on and off the electric motot a number of times to make sure the air have been bled out of the system.

Unique and patented attachment design, it reduces overall length and dimension after attached to a variable displacement vane pump, the entire combination became more compact. This cooling circulation pump intake oil from oil reservoir, deliver to cooling system. It effectively reduced oil temperature under continuous process of circulation.

Cooling circulation pump has build-in pressure setting, maintaining pressure at 3kg/cm2, protect pipe line of cooling system.

Rapid testes proven, to combine with proper cooler, it performed better cooling efficiency then cooling variable vane pump’s drain by far.
By reduce sizee of reservoir, it could save space and volume of hydraulic oil. At the end, it saved cost.
