Air Operated Double Diaphragm Pumps

Product Details:

Wilden®'s revolutionary Air-Operated Double-Diaphragm (AODD) metal pumps were specifically engineered for maximum performance and efficiency in a variety of applications. Their configuration ensures total product containment while the optimized liquid path reduces internal friction to maximize output and efficiency.

A variety of elastomer options, including Teflon® PTFE, are available to meet abrasion, temperature and chemical-compatibility requirements. The Advanced™ Series metal pumps are offered in die-cast aluminum, stainless steel and alloy C. A variety of options such as ANSI and DIN flanges, NPT/BSPT threads, and specialized air distribution systems (ADS) are available to meet specific application requirements.

Product Details:

The ALMATEC Series is based on the functional principle of double diaphragm pumps. The basic configuration consists of two external side housing with a center housing between them. Each of the side housings contains a product chamber which is separated from the center housing by a diaphragm. The two diaphragms are interconnected by a piston rod. Directed by an air control system, they are alternately subjected to compressed air so that they move back and forth. In the first figure, the compressed air has forced the left-hand diaphragm towards the product chamber and displaced the liquid from that chamber through the open valve at the top to the discharge port. Liquid is simultaneously drawn in by the right-hand diaphragm, thus refilling the second product chamber. When the end of the stroke is reached, it reverses automatically and the cycle is repeated in the opposite direction. In the second figure, liquid is drawn in by the left-hand diaphragm and displaced by the right-hand diaphragm. The liquid is displaced – and thus conveyed – by the compressed air. The diaphragms merely serve as barriers and are not pressurized. This is a fact of decisive importance for the service life of the diaphragms.
