As far as the differences between the two are concerned, the primary difference can be seen from how the screw system works inside the pumps and is maintained. The two work similarly for the purpose of transporting bulk liquids, mostly used in sewage plants.

What Is So Different About Open Screw Pumps?

As an open screw pump, the helical screw and bearings of this pump as well as its drive assembly are contained in an open trough. Because all of these components can be easily accessed by the user, this provides an easy way for users to make visual inspections and carry out any necessary repairs. The fact that all these components can be accessed helps make problems with misalignment and wear easier to detect.

Characteristics of Enclosed Screw Pumps

Different from open screw pumps, enclosed screw pumps use the same basic screw mechanism, but they are enclosed in a protective tube. This protects the screw from dirt and debris, thus eliminating the need for a concrete or steel trough for the screw pump; therefore making it easier to install in restricted areas and retrofit existing applications. Two primary types of enclosed screw pumps exist — Type S (stationer tube) and Type C (roving tube) — both having unique advantages to use. For example, Type C is considered the most efficient of the two models; however, it is slightly smaller than Type S.
