The pump casing provides a pressure boundary for the pump and contains … A screw pump works by trapping a fixed volume of fluid in the cavities formed between the screw threads and the pump housing. As the screws rotate, these cavities move the fluid from the suction side to the discharge .

Screw Pumps Gear Pumps; Screw pumps have a better suction capability and therefore work much better in a long pipeline, for more viscous oils and when air is present in the fluid. A gear pump's suction capacity is usually less than an equivalent screw pump, making it less efficient under difficult suction.
Centrifugal pumps are widely used in various industries for transferring fluids from one place to another. The efficiency and performance of a centrifugal pump depend on various factors, one of which is the design of the pump shaft. In this article, we will explore the importance of centrifugal pump shaft design and provide a PDF guide for reference.
Basic Components of a Centrifugal Pump Pump Casing (Volute) - converts high velocity (energy) into a pressure head. Impeller - imparts kinetic energy to the liquid. (accelerates the liquid)
Centrifugal Pump Basics
Centrifugal pumps basically consist of a stationary pump casing and an impeller mounted on a rotating shaft. The pump casing provides a pressure boundary for the pump and contains the fluid being pumped. The impeller is a rotating component that imparts energy to the fluid by spinning at high speeds. The shaft connects the impeller to the motor, transmitting the rotational motion to the impeller.
Centrifugal Pump Shaft Design
The design of the pump shaft is crucial for the overall performance and reliability of the centrifugal pump. A well-designed shaft should be able to withstand the stresses and forces acting on it during operation. The shaft material, diameter, length, and other factors play a significant role in determining the shaft's strength and durability.
Shaft Material
The material used for the pump shaft is typically selected based on the application and the fluid being pumped. Common materials for centrifugal pump shafts include stainless steel, carbon steel, and various alloys. The material should have good corrosion resistance, high tensile strength, and the ability to withstand high temperatures and pressures.
Shaft Diameter and Length
The diameter and length of the pump shaft are critical factors in determining its strength and rigidity. The shaft diameter should be sufficient to prevent deflection and bending during operation. The length of the shaft should be adequate to support the impeller and other rotating components without excessive vibration or deflection.
Keyways and Couplings
Keyways and couplings are used to connect the pump shaft to the motor and the impeller. Proper design and machining of keyways are essential to ensure a secure connection and efficient power transmission. Couplings should be carefully selected to accommodate misalignment and provide smooth operation.
