How a Centrifugal Pump Works

On this blog, we like to provide consumer information to give you a better idea of what we offer, why we offer it and the companies we choose to work with. Sometimes, we also like to explain how things work. We know this isn’t always for everyone, but we do get questions about how various pumps work from time to time. Here is how a centrifugal pump works.

How a Centrifugal Pump Works

A centrifugal pump transports fluids by conserving the kinetic energy of rotation into hydrodynamic energy within a fluid. Usually, the rotational force comes from an electric motor or an engine. The engine or motor powers an impeller blade, which rotates within a casing or chamber. The fluid enters into the casing, where it contacts the impeller blade.

The rotational force moves the fluid radially and tangentially outward until it has been forced away from all impeller parts. The velocity and pressure of the fluid are increased by the force from the impeller. The fluid then moves into the diffuser part of the casing. Because the diffuser is smaller in volume than the casing, the fluid gains more pressure in the diffuser. The fluid, however, moves through the diffuser with less velocity.

Centrifugal Pump Applications

Centrifugal pump systems are used in the chemical and petrochemical industries to pump water, chemicals and sewage. They are also used in many other industries for sewage and water pumping.

Turbine

If the centrifugal pump principle is applied backwards, it becomes a turbine. The pressure from the water coming in is converted to mechanical rotational energy.

Why a High Quality Pump is Important

Centrifugal pumps can develop problems, especially those of lower quality. These include: cavitation, impeller wear, corrosion, overheating and leakage. In addition, they must be primed. That’s why it’s important to only use the highest quality pumps for your operation, especially when failure or downtime can cost you thousands of dollars.
