centrifugal pump terminology|different types of centrifugal pumps : China Jul 12, 2023 · Centrifugal Pump. A centrifugal pump uses an impeller to move liquid, in contrast to other types of pump (like positive displacement and ejector designs). As the impeller rotates, energy is transferred into the fluid, propelling … The centrifugal motor pump unit, our case study, is a rotating machine, which thanks to a bladed rotor, increases the kinetic energy and projects, using centrifugal force, the liquid at the .

the pump less the vapour pressure converted to fluid column height of the liquid. Pump input or brake horsepower (BHP) is the actual horsepower delivered to the pump shaft. Pump output or water horsepower (WHP) is the liquid horsepower delivered by the pump. Pump Efficiency is the ratio of BHP and WHP.
Centrifugal pumps are widely used in various industries for transporting liquids. They work on the principle of using an impeller to impart energy to the liquid, causing it to move through the pump and into the system. Understanding the terminology associated with centrifugal pumps is essential for effectively operating and maintaining these crucial pieces of equipment. In this article, we will explore different types of centrifugal pumps, the characteristics of a centrifugal pump, how centrifugal pumps work, and why they are used in various applications.
End suction pump: a typical centrifugal pump, the workhorse of industry. Also known as volute pump, standard pump, horizontal suction pump.
Different Types of Centrifugal Pumps
1. Single Stage Centrifugal Pump
Single stage centrifugal pumps have only one impeller and are used for applications where low to moderate flow rates are required. They are simple in design and are suitable for transferring liquids with low viscosity.
2. Multi-Stage Centrifugal Pump
Multi-stage centrifugal pumps have multiple impellers stacked together in series. These pumps are capable of generating higher pressures and are used in applications where high head requirements are necessary, such as boiler feed systems and high-pressure washdown systems.
3. Self-Priming Centrifugal Pump
Self-priming centrifugal pumps have the ability to create a partial vacuum to draw liquid into the pump without the need for external priming. These pumps are ideal for applications where the pump may be located above the liquid level or where priming can be a challenge.
Characteristics of a Centrifugal Pump
- **Efficiency**: Centrifugal pumps are known for their high efficiency in converting mechanical energy into fluid flow.
- **Flow Rate**: The flow rate of a centrifugal pump is the volume of liquid that the pump can move in a given time period.
- **Head**: The head of a centrifugal pump is the height to which the pump can raise a liquid.
- **NPSH**: Net Positive Suction Head (NPSH) is a critical parameter that ensures the pump does not experience cavitation.
How Centrifugal Pumps Work
A centrifugal pump operates by using an impeller to rotate and create a centrifugal force that propels the liquid through the pump. The rotation of the impeller imparts kinetic energy to the liquid, increasing its velocity. This kinetic energy is then converted into pressure energy as the liquid exits the pump through the discharge.
Types of Pumps: Centrifugal
Centrifugal pumps are one of the most common types of pumps used in various industries due to their efficiency and versatility. They are suitable for a wide range of applications, including water supply, wastewater treatment, chemical processing, and more.
What Does Centrifugal Pump Mean?
A centrifugal pump is a dynamic device that uses an impeller to transfer energy to a liquid, causing it to move through the pump and into the system. The term "centrifugal" refers to the centrifugal force generated by the impeller rotation.
Why Are Centrifugal Pumps Used?
Centrifugal pumps are preferred in many applications due to their simplicity, high efficiency, and ability to handle a wide range of flow rates and pressures. They are used in industries such as oil and gas, water treatment, HVAC, and manufacturing.
Centrifugal Pump Diagram and Explanation
‘Centrifugal pump’ is the most common type of industrial pump. It is a pump equipped with a vaned impeller that, as it rotates, draws in liquid to its center, the eye, and …
