How Double Diaphragm Pumps Work

By Bonita Odom


Double diaphragm pumps are important systems composed of valves, chambers, thermoplastic and rubber which all work together to pump fluid across the system. They are widely used in places such as chemical industries and for hygiene purposes. They offer quality service due to better priming competence and they are also very efficient and economical to use. Double Diaphragm Pumps

The pumps are composed of two chambers which are mainly the centre of operation and they are alternately filled with fluid from a general inlet. This fluid then gets absolved via an opening in the same succession. The outlet is at the tops while the inlet is set at the bottom while the two chambers are at the sides.

Inside the chambers are diaphragms which are linked by a single shaft. This enables backward and forward motion of rubber membranes uniformly and conveniently. The appliance has pump strokes which are powered when compressed air is directed by the valve behind each membrane.

The pumping is done interchangeably. Once this is done, the suction pump of the rubber membrane opens the lower metallic ball while closing the top most one. The reason for this is to allow fluid to be drawn into the chamber via the inlet.

When air is directed in the direction of the opposite rubber membrane, the bottom ball is made to close while the one at the bottom opens. This makes the liquid to come out via the outlet because enough air has been directed from the source. This is the same process that takes place in the other chamber as the systems have two chambers for proper operations.

There are so many areas where the double diaphragm pumps are used. They best fit for use in painting, tank cleaning and in the cleaning of ships. The machines are very useful for every industrial process and their returns are promising.
