However, a diesel-powered screw pumping station in Kinderdijk (Netherlands) was built more recently with four parallel, large screw pumps that are able to … See more A majority of the cardiopulmonary bypass (CPB) systems still utilize bulky roller pumps. A direct-drive small centrifugal pump intended for second-generation CPB pump has been developed. The pump has a 50 mm diameter impeller and provides a 6 L/min flow at 3,000 rpm against 300 mm Hg. A flexible dri .

In a centrifugal pump, ‘classic’ cavitation occurs at the eye of the impeller as it imparts velocity on the liquid (see Figure 1). In a positive displacement pump, it can happen in an expanding .
The Archimedes screw, a simple machine dating back to ancient times, has found new applications in modern technology. One such application is in the design of concrete pumps, where the Archimedes screw plays a crucial role in efficiently moving concrete from one place to another. In this article, we will explore the design of an Archimedes screw concrete pump, its efficiency, and its relevance in the construction industry today.

Archimedes Screw Used Today
Pump stations are often designed to deliver a specified desired flow rate. So, the relationship shown in Eq. 10.1 is often rearranged to
Centrifugal water pumps - pumps that use a rotating impeller to create a vacuum - are widely used for pumping water in various domestic, commercial and agricultural settings. However they have their own set of limitations. Attempting to lift water beyond the 10-metre threshold described can lead to a phenomenon known as 'cavitation' - however, most modern pumps put a failsafe in .
