Air Operated 316L Stainless Steel double diaphragm pump made by Yamada. No motors, no electrical parts, no explosion hazard. You just need an air compressor. Since 1905 Yamada has been at the forefront in developing the most complete line of air operated double diaphragm pumps in the world. The patented air valve never requires lubrication. The patented non-centering spring-assisted shifter ensures a positive shift every time. Tested to last over 300 million cycles.
It is a 1:1 positive displacement pump technology using compressed air to transfer a known volume of liquid from point A to point B. There aren’t many liquids that can’t be pumped with an air operated double diaphragm pump. If there is a high solids content, higher viscosity levels, wide ranges of pH, possible dry run conditions, variable flow rates, suction lift required, or if you just want something portable, this pump technology is an excellent choice. As long as you have compressed air available this is an explosion proof way to transfer almost any liquid.
An air operated double diaphragm pump is a pneumatic pump that uses a patented air valve that directs compressed air between two sides of the pump, back and forth. It can operate on regular compressed air, clean dry air, nitrogen, or even natural gas. This air valve switching pushes compressed air behind a diaphragm and that directly applies the force to the liquid in the chamber forcing it up and out of the pump. That same force pushing one diaphragm out is drawing the other diaphragm in, as they are attached to a common center shaft, and that creates a vacuum in the opposite liquid chamber.
While one side is evacuating liquid, the other side is filling up and this process goes back and forth to create the actual liquid transfer and subsequent flow rate necessary. There are typically four ball check valves inside a standard type of pump only allowing the liquid to travel from the bottom suction manifold out through the top discharge manifold. You can run this pump anywhere from a few psi of air pressure all the way up to 125 psi of pressure depending on flow rate and discharge pressure required.
You can use this type of pump if you have solids, a thicker liquid, self-priming requirements, dry running potential, explosion proof specs, variable flow rates, shear sensitive liquids, something submerged, portability required, or the application calls for dead heading. Common applications include winery pump over transfers, filter presses, adhesives, paints, chemical additives, distilled spirits, mixing tanks, filling machines, drum pumps, general liquid transfer and almost all fluid handling systems.
