Progressive cavity pump gently pumps fluids
In many different sectors , media ranging from fluid to pasty have to be gently pumped . In industry , media that is sensitive to shearing , such as paints , pastes or oils , need pumping just as salves or toothpastes do in the pharmaceutical and cosmetic sectors . Even in food production , substances such as molasses or juice concentrates change their consistency if processed too violently . The solution comes in the form of modern positive displacement pumps with eccentric worms . With almost no pulsation and virtually no shearing , they pump geometrically defined volumes per revolution and can even tolerate small solids in the medium . Thanks to clamp connections and a modular structure , they can be used universally and are often a cost-effective solution .
