ANEST IWATA Double Diaphragm Pumps operate on a pneumatic drive principle. Compressed air is alternately directed to the rear chambers of two flexible diaphragms connected by a common shaft.
The reciprocating motion of the diaphragms creates alternating suction and discharge strokes, allowing the fluid to be drawn in and expelled through non-return valves. This design provides a continuous and stable flow rate without the use of electrical or mechanical drive components in contact with the fluid.
