If gas or air are present, remove them before the liquid makes it to the screw pump. High Pressure With the Discharge of Liquids. A high discharge pressure is often tied to a blockage in the discharge line. It also occurs if the .
Three-screw pumps, also known as three-spindle screw pumps, are a type of positive displacement pump that are widely used in various industries for their efficiency and reliability. These pumps are designed with three intermeshing screws that rotate inside a casing, creating a continuous flow of fluid. In this article, we will explore the design, working principle, and applications of three-spindle screw pumps.
Three-Screw pumps are part of the family of positive displacement pumps. They are equipped with a drive spindle and two auxiliary spindles housed in a liner. A Special profiling of the
Design of Three-Screw Pump
Three-screw pumps consist of a drive screw and two idler screws that rotate within a casing. The screws are precision machined to fit tightly within the casing, creating sealed chambers between the screws and the casing walls. As the screws rotate, they move the fluid axially along the length of the screws, from the suction side to the discharge side.
The design of three-screw pumps allows for a smooth and pulsation-free flow of fluid, making them ideal for applications where a constant and uniform flow is required. The tight clearances between the screws and the casing walls also contribute to the high efficiency of these pumps.
Working Principle of Three-Screw Pump
The working principle of a three-screw pump is based on the intermeshing action of the screws within the casing. As the screws rotate, they create a series of sealed chambers that trap and move the fluid from the inlet to the outlet of the pump. The rotation of the screws also generates a low-pressure area at the suction side, allowing the pump to self-prime and handle entrained air and cavitation effectively.
Three-screw pumps are known for their ability to handle a wide range of viscosities and temperatures, making them suitable for pumping various types of fluids, including lubricating oils, hydraulic fluids, and fuel oils. The design of these pumps also makes them resistant to vapor lock, ensuring continuous and reliable operation.
Applications of Three-Screw Pump
Three-screw pumps are commonly used in power plants, refineries, chemical plants, and other industrial facilities where a reliable and efficient pumping solution is required. These pumps are often used for transferring lubricating oils, hydraulic fluids, and other viscous liquids in process systems.

Now housing 15 Wood Screw Pumps, it can move over 6 billion US gallons (23,000,000 m 3) of water a day. . It was later revealed that 16 of New Orleans' 148 drainage pumps and 3 of 5 turbines which provide power to the pumping system were out of service, severely reducing pumping capacity during the rain event.
