Desilters utilize smaller hydrocyclones and are used to process mud that has already been cycled through the desander. The number of cones in a desilter is greater than the corresponding desander as the smaller cones accommodate lower flow rates. Desilters are comprised of either 4" or 5" cones whereas each 4" cone is capable of removing 50% of .
Centrifugal pumps are one of the most commonly used types of pumps in various industries for fluid transportation. They are known for their simplicity, efficiency, and reliability. This presentation will cover the basics of centrifugal pumps, including their operating principles, energy conversion, components, NPSH concept, pump rating calculation, and affinity laws.

Operating Principles
Centrifugal pumps work based on the principle of centrifugal force. The pump uses an impeller that rotates at high speeds to create a centrifugal force that pushes the fluid towards the pump outlet. As the impeller rotates, it draws the fluid into the pump casing through the suction inlet and then accelerates it before discharging it through the outlet.
Energy Conversion
The energy conversion in a centrifugal pump occurs as the mechanical energy supplied to the pump shaft is converted into kinetic energy and potential energy of the fluid. The impeller's rotation imparts kinetic energy to the fluid, which increases its velocity. This kinetic energy is then converted into pressure energy as the fluid moves through the pump casing and exits at a higher pressure.
Components in Centrifugal Pump
A centrifugal pump consists of several key components, including the impeller, pump casing, shaft, bearings, and seals. The impeller is the rotating component that imparts energy to the fluid, while the pump casing houses the impeller and directs the flow of fluid. The shaft connects the impeller to the motor, and the bearings support the shaft. Seals are used to prevent leakage of fluid from the pump.
Concept of NPSH
NPSH, or Net Positive Suction Head, is a critical parameter in centrifugal pump operation. It refers to the total head available at the pump suction inlet to prevent cavitation. Cavitation occurs when the fluid pressure drops below the vapor pressure, causing the formation of vapor bubbles that implode, leading to damage to the pump components. NPSH is calculated based on the system pressure, fluid properties, and pump design.
Pump Rating Calculation
The performance of a centrifugal pump is rated based on several parameters, including flow rate, head, efficiency, and power consumption. The pump rating calculation involves determining the pump's operating point on the pump curve, which represents the relationship between flow rate and head. By selecting the appropriate pump size and speed, the pump can operate at its optimal efficiency and performance.
Affinity Laws
Centrifugal pumps are the rotodynamic machines that convert mechanical …
