We are using Kawasaki make external gear pump for pressure boosting of polymer. In this pump suction pressure is hunting. Can anyone guide me a possible reasons.
The pump details are as follows.
Operation condition.
Name of liquid - Pet Polymer
viscosity - 2000-3000 poise
Specific gravity - 1.2
Inlet pressure - 10 kg/cm2
Outlet pressure - 200 kg/cm2
Theoretical disp. - 930 cc/rev
thank u
