The Centrifugal Pump

In 1689 the physicist Denis Papin invented the centrifugal pump and today this kind of pump is the most used around the world. The centrifugal pump is built on a simple principle : liquid is led to the impeller hub and by means of the centrifugal force it is flung towards the periphery of the impellers.
The construction is fairly inexpensive, robust and simple and its high speed makes it possible to connect the pump directly to an asynchronous motor. The centrifugal pump provides a steady liquid flow, and it can easily be throttled without causing any damage to the pump.

If a pressure difference occurs in the system while the centrifugal pump is not running, liquid can still pass through it due to its open design.

The difference demands on the centrifugal pump’s performance, especially with regard to head, flow, and installation, together with the demands for economical operation, are only a few of the reasons why so many types of pump exist.
