What Are the 3 Types of Centrifugal Pumps?

When selecting a pump, it is important to consider its application. Some applications require corrosive liquids, and others require pumps that can withstand milder conditions. For example, hydrofluoric acid is frequently pumped in the pulp and paper industry. In other applications, corrosive media require pumps made of graphite monolithic ceramic or composite materials. If corrosive liquids are expected to pass through the pump, it is important to consult a metallurgist for guidance.

Generally, centrifugal pumps consist of an impeller. This is the rotating part of the pump, and is attached to a shaft by an electric motor. The impeller is covered with a watertight casing, and is responsible for imparting velocity to liquid.

Horizontal centrifugal pumps are easy to install and maintain. They feature easy access to internal parts, and can be coupled with external accessories. Horizontal pumps are larger than vertical pumps, and have lower working temperatures and pressures. There are several types of centrifugal pumps: single-stage pumps, double-stage pumps, and multistage pumps. Single-stage pumps feature a single impeller, while double-stage pumps have two impellers.

End-suction pumps handle clean or dirty liquids. They are used in many industries, including refrigerant and cryogenics. They can also handle thin liquids and solids. Some of them can even be used in corrosive services. When choosing a pump, it is important to consider its application.

Radial pumps are similar to horizontal pumps, but they rotate 90 degrees. They are used when pressure is required to reduce the flow of fluid. In addition, radial pumps are able to handle higher pressures. They also handle higher flow rates. These pumps are more efficient than horizontal pumps.

The three basic types of centrifugal pumps include: centrifugal, horizontal, and vertical centrifugal pumps. The difference in these three types is the kinetic energy of the impeller. As the impeller rotates, the pressure head of the liquid is increased. This fluid is directed through the piping system. Ultimately, the liquid is pumped away from the pump by a discharge nozzle.

Centrifugal pumps are often categorized according to the amount of fluid they move. The flow patterns are influenced by the design of the impeller and casing. The three main types of centrifugal pumps are single-stage, multistage, and vertical centrifugal. Each type of centrifugal pump has its own advantages. Most of them are highly efficient, have an incredibly wide capacity range, and require very little maintenance.

The main advantage of centrifugal pumps is that they are easy to maintain and cost less than other pumps. However, it is important to choose a pump that meets the needs of the application. For example, chemical-specific pumps are recommended for applications where hazardous chemicals are present.

Positive displacement pumps are a popular choice for some applications. They're particularly useful for handling high-viscosity fluids, moving liquids gently, and a range of other applications. Some are sealless and self-priming.
