"Suntech" Three Screw pumps employ just three screw elements - one power screw and two idler screws running in the three precision bores in the housing. These screws are so profiled that they form a liquid tight seal between the thread. As the screws rotate, cavities are formed where liquid gets trapped and conveyed from one end of the infinite stroke. This results in smooth, pulsation free flow with extremely low noise and vibration levels, almost impossible to be achieved by any other design of positive displacement or other types. |
