What’s a Screw Pump?
One of the most common questions we here is, "What is a screw pump?". Unfortunately, screw pump is often a generic term that groups a one, two and three screw pump into one category. Each 'screw pump' operates on the same basic principal of a screw turning to isolate fluid and convey it. However, the mechanical design of each is different. The primary difference in one, two three or multiple screw pumps is the method in which the rotor/pumping element is supported within the casing. 'Screw pump' configurations may include single screw/eccentric screw/progressive cavity, external bearing, timed twin screw pumps, small three screw pumps on lube oil services/machinery support services, large crude oil transfer pumps or even Archimedes-style flood control pumps.
