Centrifugal Pump Challenges

Designed by the experts in centrifugal pump design.

Unique molded magnet driver:

• Fills internal space

• Assures balanced magnet

• Consistent performance

Pump Assembly Manufacturing Process

100% Quality Control Process Designed for manufacturability Simple assembly Minimal parts Ultrasonic weld

Simple Assembly = High Quality

Internal Features

4. Impeller floats while

pumping

Flow enters the inlet rinsing the top bearing

Centrifugal force moves fluid to the outside

Fluid not leaving the pump moves

back to the low pressure center,

rinsing the bottom bearing Recirculation is

completed by fluid moving up thru the central channel

As fluid moves up thru the central channel, it lifts the impeller off the bottom bearing, opposing the magnetic forces, reducing

bearing load and bearing friction. The impeller literally floats.

Computational Flow Dynamics

Large changes in velocity would indicate vortexing.

Note steady increases from center to end of vane tips.
