The characteristic of this GM-G series  polymer melt equipment pump beneath the reaction kettle as discharge pump.




one)it can be used on high temperature (350ºC),high pressure(15MPa),high viscosity (40,000Pas)working condition.


2)The pressure flow pulsation is very small, and even can achieve linear output flow,easy to control


3)Good self-priming performance, can be used in the entrance with the operation condition of vacuum (.05 ~ 0.09 MPa) 


4)Precise structure, high precision, long service life
