Rotary Diaphragm

Rotary diaphragm pumps use the Charles Austen patented technology. The flow of liquid is initiated by an eccentrically mounted bearing on a drive shaft revolved within a flexible diaphragm. As the shaft rotates, the bearing flexes the diaphragm, squeezing liquid through the pump. These pumps have outstanding self-priming characteristics and are of a valve-less, seal-less design.

The MegaBlue is an essential pump when tackling condensate removal, as with the entire BlueDiamond range, the MegaBlue uses the patented BlueDiamond rotary diaphragm technology. Whilst being exceptionally quiet, it is also able to pump up to six storeys high, making the MegaBlue ideal for installations where distance is required.
