Three screw pumps also find extensive use in crude oil pipeline service as well as gathering, boosting and loading of barges and ships. They are common in engine rooms on most of the world"s commercial marine vessels and many combat ships.

Subject to material selection limitations, three screw pumps are also used for polymer pumping in the manufacture of synthetic fibers such as nylon and lycra.

Designs are now available in sealless configurations such as magnetic drives and canned arrangements. The magnetic drive screw pump is used extensively for pumping isocyanate, a plastic component which is an extremely difficult fluid to seal using conventional technology.

Three screw pumps are renowned for their low noise levels, high reliability and long life. Three screw pumps are capable of water injection services (Tritec) as well as high pressure coolant service for machine tools (Emtec).

As the quantity of discharged hydraulic fluid is constant irrespective of the revolution position of an axis, there hardly occurs a pressure pulsation.

As the idler rotor auto-rotates by the delivered hydraulic fluid and the biting power between the rotors is small, little wear and a long life is achieved.

A screw pump is made up of various components such as; a casing, a screw (depending on the type of screw pump; it can contain 1 screw up to 5 screws), bearings, a seal, a motor adapter and a drive shaft. Screw pumps are quite simple in construction.

The screw pump, as the name implies, the form of the screw is similar to a screw thread and hence by rotating it, the fluid moves along the screw thread from the suction side to the discharge side of the pump. Due to very close clearances inside the pump, the volumetric efficiency is high especially with viscous fluids as this reduces the amount of slippage of the fluid from the high pressure to the low pressure side. The pump itself like any positive displacement pump does not produce pressure, it only moves fluid but it is the actual system which produces back pressure due to friction loss.

Screw pumps are mostly used on fluids of a higher viscosity, moving these fluids with screw pumps results in energy efficient and a relatively compact machine when compared to other pump types i.e centrifugal pump. For screw pumps with more than 2 screws, they are normally used on lubricating fluids only because the screws are not geared together and are relying on the fluid to lubricate the screws.

With a twin screw pump, the screws are geared which prevent the screws contacting each other and can therefore be used on non-lubricating fluids, chemicals and food-stuffs etc Twin screw pumps are capable of a higher flow rate than higher screw pump types i.e more than 2 screws.

There are various types of a screw pump depending on the number of screws – 1 screw up to 5 screw variations with the 2 screw pump (also called the twin screw pump) being the most common where the gears must be together to prevent contact. The twin screw pump can be fairly forgiving in terms of being able to handle entrained air or gas, including slugs of gas, whereas the 3 screw pumps cannot be used in this instance as there is a real chance that the screw would touch together.

When there is more than 1 screw involved, it is often referred to a Multi screw pump. The construction is relatively simple and is capable of a higher flow rate. They can also be used in self-priming applications with the correct suction piping configuration.

Screw pumps are capable of much higher flows and pressures compared to gear pumps.  Gear pumps limit are 250m3/hr up to 16 bar whereas a twin screw pumps limit is 500m3/hr up to 16 bar and a 4 screw pumps limit is 1500m3/hr up to 80 bar. Gear pumps work by intermeshing gears with external or internal type.

As gear pumps are virutally “single stage positive displacement” pumps  with less pressure capability than screw pumps. Screw pumps have a longer screw where the pressure is divided along the length of the screw. A twin screw pump has a much greater ability of handling solids whereas a gear pump is restricted to clean fluids.

Screw pumps delivers a known quantity of fluid for every revolution whereas the Centrifugal pump is dependent on the system conditions which in turn may affect the flow rate. Due to the volumetric efficiency of screw pumps, they will usually require less energy i.e. smaller motor when compared to a centrifugal pump on the same application.

Screw pumps depend heavily on the close internal clearances being maintained t o remain efficient. There is no clearance adjustment facility on screw pumps whereas Centrifugal process pumps will usually have an impeller adjustment facility so it can restore the running clearance. Screw pump parts are inherently self-priming whereas Centrifugal pumps would require a priming system, foot valve or self-priming casing design.
