Design and construction are two of the main differences between a pump and a booster pump. A pump is designed to move a fluid from one place to another while a booster pump is designed to increase the pressure of a fluid.
Centrifugal pumps are widely used in various industries for transferring fluids. They work on the principle of converting the rotational kinetic energy of an impeller into hydrodynamic energy of the fluid being pumped. Centrifugal pumps are classified into many types depending on various factors such as the number of impellers, impeller design, case-split orientation, type of volute, bearing support, shaft orientation, and other miscellaneous factors.
The Centrifugal pumpis working based on the centrifugal force and the name follows the same. Fluid enters into the pumps, gets the energy from the centrifugal force of the impeller, and raised its velocity and pressure. Due to this pressure, the liquid is transferred from one place to another. See more
Number of Impellers or Stages
The number of impellers or stages in a centrifugal pump determines its capacity to generate pressure. Single-stage pumps have only one impeller, while multi-stage pumps have multiple impellers arranged in series to achieve higher pressure levels.
Impeller Design
The design of the impeller plays a crucial role in the performance of a centrifugal pump. Different impeller designs, such as open, semi-open, or closed, are used based on the specific requirements of the application.
Case-Split Orientation
The orientation of the case-split in a centrifugal pump can be horizontal or vertical. Horizontal split-case pumps are more common and easier to maintain, while vertical split-case pumps are used in applications where space is limited.
Type of Volute
The volute is a key component of a centrifugal pump that helps in converting the kinetic energy of the fluid into pressure. Different types of volutes, such as single volute, double volute, or concentric volute, are used based on the pump's design requirements.
Bearing Support
Bearing support is essential for the smooth operation of a centrifugal pump. The type of bearing support used in a pump can impact its reliability, maintenance requirements, and overall performance.
Shaft Orientation
The orientation of the shaft in a centrifugal pump can be horizontal or vertical. Horizontal shaft pumps are more common and easier to install, while vertical shaft pumps are used in applications where space constraints exist.
Miscellaneous Factors
The main parts of the Centrifugal Pump are: 1. Impeller 2. Casing 3. Backplate 4. Suction & Discharge Nozzles 5. Suction pipe 6. A foot valve 7. Strainer 8. Suction nozzle or suction
A pump’s outlet (discharge) piping flow characteristics normally will not affect the performance and reliability of a pump, with a few exceptions. In some cases, sudden valve closures can cause excessively high pressure spikes (surge or water hammer) to be reflected back to the pump, possibly causing damage to the pump, system piping or .While some pump manufacturers that use pressure (differential pressure which is measure the deviation between Suction and Discharge flange ~ HEAD) to .
