Does a Bellow Pump Intermittently?
A. All Diaphragm & Bellows pump Intermittently. Most diaphragms only take a 1/2″ stroke or less so the pulsation is not noticeable. The American Eagle Bellows makes a huge 1 & 3/4 inch stroke so the 3 & 1/2 times more volume of air is more noticeable. The Intermittent Pulsation not only provides more Volume of Air it also is much more efficient in Circulating the Water. The Bellow is the most effective way to draw the bottom water to the Diffuser, Rejuvenating it with Fresh Smelling Air and with the aid of the Intermittent Pulsation it Aerates & Circulates the entire pond from Bottom to Top.
