Centrifugal pumps are hydrodynamic machines used to move liquids efficiently. This makes them indispensable machines in many industries. Centrifugal pumps can handle large volumes of fluids and can move an impressive range of fluids - from corrosive and abrasive to hot, cold, viscous or contaminated. Their versatility and adaptability make centrifugal pumps ideal for integration into many applications.
Whether in water supply, marine applications or chemical processes, they can be optimally designed. Their simple and robust technology makes them not only extremely reliable, but also extremely durable. Features that make centrifugal pumps the most widely used pumping technology in the world.
In radial centrifugal pumps, the fluid is delivered and the pressure increase is brought about in a rotating impeller with vanes. This impeller is driven by a drive motor via a shaft and transfers mechanical energy to the pumped fluid continuously flowing through the impeller. The liquid enters the impeller axially and is accelerated from the inside to the outside by the effect of centrifugal force. This results in a transfer of energy into pressure and velocity energy. At the outlet of the impeller, the liquid enters the volute casing where the flow velocity is again slightly reduced. As a result of further energy conversion, the pressure increases. Through the volute, the liquid is directed to the pump outlet.
Centrifugal pump technology is an integral part of many industries. Due to their simple design, operating efficiency and wide range of applications, centrifugal pumps are often the preferred pump type. Below are some of the key benefits that make centrifugal pump technology the first choice.
Centrifugal pumps are easy to maintain and repair, saving time and money. Their robust design, which is less prone to failure, minimizes maintenance costs and ensures reliable operation.
Centrifugal pumps are highly efficient at handling water-like fluids, whether hot or cold, neutral or aggressive, clean or contaminated. As a result, they can be used in a wide range of applications.
Centrifugal pumps are characterized by their remarkable versatility. They can be used in various applications such as water supply, chemical industry or maritime sector. They can also be adapted to specific processes. This includes the selection of suitable materials, the design for optimal installation or the appropriate shaft seal for the process fluid. This adaptability makes them a highly flexible solution.
Choosing the right centrifugal pump requires experience, as a large number of application-specific factors determine the optimum pump design. Important criteria include the operating data, the nature of the pumped medium, the desired type of installation and compliance with specified standards or regulations. All these aspects influence the selection of pumps as well as their specific design features.
