What is the difference between Open and Enclosed screw pumps?

A screw pump, also known as a water screw, is a positive-displacement (PD) pump that moves fluid solids or liquids along the screw axis using one or more screws. In its most basic form, a single screw rotates within a cylindrical cavity, moving materials along the screw's spindle. This ancient structure is still used in a variety of low-tech applications, including irrigation systems and agricultural machinery for transporting grain and other solids.

Engineers have been using screw pumps for wastewater plant lift stations, storm water pumping, and other industrial applications for decades. These pumps are designed to move large amounts of liquid, but they also allow large objects to pass through without clogging the system. This means that water contaminated with various objects can be easily pumped.

Screw pumps can also be used when there is no water present!

This means that no additional parts are required to prevent the pump from running in dry conditions. Regardless of how little water is present, the pump can continue to operate. Screw pumps are not only efficient, but they also require little maintenance. The pumps are designed with few moving parts that run at a slow speed all of the time. This innovative design reduces wear and tear as well as the need for repairs.

Screw pumps can be found in a wide range of industrial settings. Engineers must, however, choose between two types of screw pumps: open and enclosed.

It is now critical to understand the distinctions between these two designs.

An open screw pump is made up of four parts: a spiral screw, upper and lower bearings, and a drive assembly. Open screw pumps are placed at an angle within concrete or steel troughs, exposing their screw-shaped design.

Enclosed screw pumps are similar to open screw pumps, but they are encased within a tube, so the screw-shaped design is hidden. Because the pump is contained within a tube, it does not require the use of a cement or steel trough.

Enclosed screw pumps are classified into two types: Type S and Type C. Both are enclosed within tubes, but the tube in a Type S design is stationary, whereas the tube in a Type C design is not. Type C pumps have two spiral flights welded to the inside of the pump's tube, which rotates as it works.

The Advantages of Open Screw Pumps

The open screw pump is well-known for its ease of use and dependability. These pumps are already extremely low maintenance, but they can be made even more so. If the lower bearing is designed with a permanently greased lubricated roller bearing or a sleeve bearing, wear and tear will be reduced even more.

If a repair is required, an open screw pump may be easier to identify the problem than an enclosed pump. This is due to the open design of an open screw pump, which allows you to see all of the moving parts.

The Advantages of Enclosed Screw Pumps

Enclosed screw pumps, as previously stated, are encased within a tube, eliminating the need for a steel or concrete trough. It is considered easier to install than an open screw pump because it does not require a trough. It's also a better option for customers who need a quick replacement but don't have the time to install a trough.

Both open and enclosed screw pumps are efficient, but the Type C pump is the most efficient. Indeed, the Type C pump is estimated to be 5-10% more efficient than the open screw pump, which is why it has become a popular choice.

Conclusion

There are advantages to both open and enclosed screw pumps, making it difficult to decide which is best for your needs. Instead of focusing on the pump's design, consider how it will be used.

When choosing a screw pump, the following factors should be taken into account:

1: Capacity.

2: Speed.

3: Inclination.

4: The number of flights.

5: Horsepower.
