The three-rotor design consists of a driving screw and two idler screws. The motor shaft rotates the driving screw, which in turn rotates the intermeshing twin idler screws. This type of pump can handle a wide range of viscosities, up to 35,000 cst, and changes in fluid viscosity have little effect on the pumped flow rate.

Centrifugal pumps are widely used in various industries for transferring fluids from one place to another. They rely on the principle of centrifugal force to move the liquid through the pump. Understanding the main components of a centrifugal pump is essential for proper maintenance and operation. In this article, we will explore the key parts of a centrifugal pump and their functions.
Centrifugal pump is a hydraulic machine which converts mechanical energy into hydraulic energy by the use of centrifugal force acting on the fluid. These are the most popular and
Impeller
The impeller is a crucial component of a centrifugal pump responsible for increasing the kinetic energy of the flow. It is a rotating disk with vanes that accelerates the fluid outward. As the impeller spins, it creates a low-pressure zone at the center, causing the liquid to move towards the outer edges. This action increases the velocity of the fluid, generating the centrifugal force necessary for pumping.
Casing (Volute)
The casing, also known as the volute, is another essential part of a centrifugal pump. It surrounds the impeller and contains the liquid being pumped. The casing is designed to convert the kinetic energy generated by the impeller into pressure energy. As the fluid leaves the impeller, it enters the casing, where the gradual expansion of the volute converts the velocity head into pressure head. This transformation allows the pump to maintain a consistent flow rate and pressure.
Shaft
The shaft in a centrifugal pump connects the motor to the impeller, transmitting the rotational energy needed to drive the pump. It plays a critical role in maintaining the alignment and stability of the rotating components. The shaft must be carefully designed to withstand the mechanical stresses and vibrations associated with pump operation. Proper lubrication and maintenance of the shaft are essential to prevent premature wear and ensure efficient pump performance.
Bearing Housing
The bearing housing supports the shaft and provides a mounting point for the bearings that facilitate smooth rotation. Bearings reduce friction between the shaft and the housing, allowing the impeller to spin freely. Properly lubricated bearings help minimize wear and extend the lifespan of the pump. The bearing housing also helps to maintain the alignment of the shaft, ensuring that the rotating components operate smoothly and efficiently.
Seal Assembly
The seal assembly in a centrifugal pump prevents leakage of the pumped fluid and maintains the integrity of the system. It consists of various components, including mechanical seals, gaskets, and packing materials. The seal assembly is crucial for maintaining the efficiency and reliability of the pump by preventing fluid loss and contamination. Regular inspection and replacement of seals are essential to prevent costly downtime and ensure optimal pump performance.
Suction and Discharge
The suction and discharge connections are where the fluid enters and exits the pump. The suction side is typically larger to allow for the intake of the liquid, while the discharge side is smaller to create pressure and push the fluid out of the pump. Proper sizing and positioning of these connections are essential for efficient operation and optimal performance of the centrifugal pump.
Motor
The motor provides the power necessary to drive the pump and rotate the impeller. It is typically connected to the pump shaft via a coupling or belt drive. The motor must be appropriately sized and matched to the pump's requirements to ensure reliable operation. Regular maintenance of the motor, including checking for proper alignment and lubrication, is essential for preventing downtime and extending the pump's lifespan.
