In a centrifugal pump, ‘classic’ cavitation occurs at the eye of the impeller as it imparts velocity on the liquid (see Figure 1). In a positive displacement pump, it can happen in an expanding piston, plunger or suction-side chamber in a gear pump. Reciprocating pumps, for example, should not be used in self-priming applications without .
Centrifugal pumps are widely used in various industries for pumping fluids efficiently. One crucial aspect of ensuring the optimal performance of a centrifugal pump is the design of its intake structure. The intake design plays a significant role in the overall efficiency and reliability of the pump system. In response to this evolving need, the Hydraulic Institute has improved and expanded its recommendations for designing intake structures for centrifugal, vertical turbine, mixed-flow, and other types of pumps. In this article, we will delve into the various aspects of centrifugal pump intake design, including hydraulic pump intake design, American National pump intake design, suction pump intake design, pump bell intake design, pump intake diameter calculation, and hydraulic pump intake standards.

Pump Intake Design
The design of the pump intake is critical for ensuring the smooth and efficient flow of fluid into the pump. A well-designed intake structure helps in reducing turbulence, minimizing air entrainment, and preventing cavitation. The intake design should be optimized to provide a uniform flow profile to the pump impeller, thus improving the overall performance of the pump system.
Hydraulic Pump Intake Design
Hydraulic pump intake design involves the selection of appropriate intake structures, such as bell mouths, strainers, and intake pipes, to ensure the efficient operation of the pump. The intake design should be based on the specific requirements of the pump system, including the flow rate, fluid properties, and operating conditions. Proper hydraulic pump intake design can help in reducing energy consumption, extending the life of the pump, and minimizing maintenance costs.
American National Pump Intake Design
The American National Standards Institute (ANSI) has established guidelines for pump intake design to ensure the safe and reliable operation of centrifugal pumps. These standards cover various aspects of pump intake design, including intake velocity limits, intake pipe sizing, and intake structure materials. Adhering to ANSI standards for pump intake design can help in meeting regulatory requirements and ensuring the long-term performance of the pump system.
Suction Pump Intake Design
Suction pump intake design is crucial for preventing cavitation and ensuring the proper functioning of the pump. The design of the suction intake should consider factors such as the distance between the pump and the fluid source, the elevation difference, and the presence of any obstructions in the intake line. Proper suction pump intake design can help in maintaining the required suction pressure and flow rate for the pump to operate efficiently.
Pump Bell Intake Design
Pump bell intake design involves the use of bell mouths or intake hoods to guide the flow of fluid into the pump intake. The bell mouth design helps in reducing turbulence and preventing air entrainment, thus improving the efficiency of the pump system. The size and shape of the pump bell intake should be carefully selected based on the specific requirements of the pump and the operating conditions.
Pump Intake Diameter Calculation
The calculation of the pump intake diameter is essential for determining the size of the intake pipe or bell mouth required for the pump system. The intake diameter calculation should consider factors such as the flow rate, fluid velocity, and pressure drop across the intake structure. Proper sizing of the intake diameter is crucial for ensuring the optimal performance and efficiency of the pump system.
Pump Intake Calculation
Pump intake calculation involves the determination of various parameters, such as the intake velocity, pressure drop, and flow distribution, to optimize the design of the pump intake. The intake calculation should be based on the specific requirements of the pump system and the operating conditions. Accurate intake calculation can help in reducing energy consumption, minimizing maintenance costs, and extending the life of the pump.
