Centrifugal pump
A centrifugal pump is a simple and economical type of pump. It is an effective solution for transporting large volumes of liquid, typically with low viscosity, due to its high performance. Common applications for centrifugal pumps therefore include water, wastewater, various types of oil, solvents, acids and bases.
A centrifugal pump is a highly versatile pump that easily and economically solves a wide range of tasks in a setup. Centrifugal pumps utilise centrifugal force to transport liquids out of the pump chamber using a rotating impeller, and compared to other types of pumps, a centrifugal pump only uses a limited amount of energy.
At Alflow, we sell centrifugal pumps for various tasks in several industries. The pumps are produced in durable materials that help ensure an efficient experience. Check out the selection of centrifugal pumps from leading manufacturers on this page and transport the given liquids in the best way.
What is a centrifugal pump?
A centrifugal pump is a rotodynamic, simple and economical pump type. It is typically the most common sanitary pump type. Some of the advantages of centrifugal pumps are the relatively low purchase price, the variety of types, the simple design and easy maintenance.
Centrifugal pumps are made to transport water and similar liquids with the same viscosity. It is the most common type of pump and is incredibly easy to maintain. The construction of a centrifugal pump is robust and the high speed of the pump makes it possible to connect to an asynchronous motor.
As with centrifugal pumps, an asynchronous motor is also among the most popular motor types. This is because it provides the pump with a smooth flow of liquid, which allows you to throttle down the flow of liquid without damaging the pump. This makes the pump incredibly versatile, which means it's suitable for a variety of professional applications.
What are typical centrifugal pumps?
There are several types of centrifugal pumps, including standard pumps for most applications, multi-stage centrifugal pumps that work as pumps in a series, aseptic centrifugal pumps for optimal product safety, and high clean pumps for pharma or similar applications that require better cleaning capabilities.
Find a multi-purpose centrifugal pump
Centrifugal pumps can of course be used for several different purposes. Below we have mentioned some of the places where centrifugal pumps are used:
- Deliver water from a well or tank
- Circulating water in a closed system
- Increase the pressure in a cold water system
Centrifugal pumps ensure that the water is brought to the centre of the rotating runner, also known as the hub. The fluid is then brought out towards the periphery of the runners using rotational kinetic energy, which then becomes hydrodynamic energy. This is possible due to centrifugal force.
As you probably know, a sewage pump actually uses the same method, but is designed to handle unclean liquids as it has a runner that prevents dirt and objects from getting stuck in the pump. Should a pressure difference occur in the installation, the liquid can still be transported through the pump. It is built on an open system, so even if the pump is not running, the fluid is still transported.
Fluids for centrifugal pumps
If the pump needs to work with low-viscosity fluids other than cold water, centrifugal pumps are still suitable for multiple installations. As long as the fluid is clean and still has a similar viscosity, the pump can still work. For example, the pump is compatible with:
- Mild acids and bases
- Thin oils
- Salt water
- Chemicals and aggressive liquids
- Solvents
If you need to transport liquids other than water, a centrifugal pump could be for you. If you're dealing with a toxic medium, it's a good idea to choose a centrifugal pump with a magnetic coupling. This prevents the pump from releasing toxic media or vapours into your surroundings. Using Alflow centrifugal pumps should be efficient, and using our magnetic drive pumps makes it so.
How to operate a centrifugal pump
Alflow centrifugal pumps are incredibly easy to use and connect. The smart pumps are equipped with an electric motor that uses centrifugal force to propel the water in another circuit. In other words, the medium flows radially outwards with the help of the rotating energy. The pump is mounted, the motor is switched on and the fluid will be directed further.
You can also find self-priming pumps in our selection that help evacuate air from the suction side without external aids. In order to be able to transport liquids, the pump must have a sufficient amount of liquid in the pump housing. If there is not enough water in the pump housing, the centrifugal pump can be damaged due to dry running. A self-priming pump can help with this, reducing the risk of water hammer and damage.
How to find the right centrifugal pump?
To ensure a correct pump selection, it is important to consider all necessary process and site data as well as customer preferences. Among other things, it is important to know the process type, capacity, inlet pressure, head, NPSHa, cavitation risk, voltage supply, frequency, installation conditions and fluid data such as temperature, viscosity, abrasives, solids, etc.
