Impeller

Radial vane centrifugal impeller channels type, with dynamic and static balancing, is made of welded carbon steel or stainless steel.

The semi-closed  impeller type guarantees a high oxygen transfer efficiency, the no- clog open type has a high pumping capacity.

Impellers are projected to obtain a control of oxygen transfer by changing:

· Sense of rotation

· Immersion of impeller

· Rotation speed

Oxygen supplying is comprised in a 30% to 100% range of maximum capacity
