Closed impellers have flatter efficiency curves than open impellers and therefore offer better low-flow efficiency. For example, the difference between a closed single-vane impeller and an open single ...

In its ongoing quest to push the boundaries of performance, pump manufacturer, KSB Group, has developed a special impeller to further improve the suction characteristics of its Movitec multistage ...

To improve the quality of suction of its Movitec multistage centrifugal high-pressure pumps, pump manufacturer KSB Group developed a new impeller that can be used with a number of Movitec variants ...

The impeller includes a newly designed stage casing, which serves to improve the net positive suction head of a pump and vanes that allow a slightly diagonal throughflow. To improve the quality of ...
