A diaphragm or membrane pump, is a type of positive displacement pump that enables users in industries to standardise on the same which is suitable for a wide variety of fluids. The only requirement it needs is compressed air supply. The fluid that is being handled requires a gentle pumping action through chemically or physically. The aggressive diaphragm option offers an efficient and low maintenance solution.
 
How does a diaphragm pump work?
 
A diaphragm pump utilises two flexible diaphragms, which reciprocate back and forth, that create a temporary chamber. The flexible diaphragms both draw in and expels fluid through the pump. The diaphragms work as a separation wall between the air and the liquid. They are connected by a shaft in the centre section.
 
When the diaphragms move away from the chamber, they lower the pressure and fluid rushes in. When they push back into the chamber, they further increase the pressure and the fluid flows out. This type of pump consists one way check valves through which the fluid is passed out. This process ensures that the fluid only flows in the proper direction through the chamber.
 
Types of  diaphragm pumps
 
There are different types of diaphragm pumps. They are air operated, electric driven and piston operated. The cast of diaphragm pumps are typically divided into metallic and non metallic materials. However, there are some specific diaphragm pumps that are designed for high clean purposes. These are constructed with polished stainless steel.
 
How are diaphragm pumps used?
 
Diaphragm pumps are used in a number of industries. There are many construction materials available to produce different configurations for difficult fluids. In addition to the fluid handling properties, diaphragm pumps can be specified for EC1935/2004, ATEX zones, FDA and 3A hygienic applications amongst other industry compliance measures.
 
What they're great for?
 
Their unique design of diaphragm pumps allows them to transfer highly abrasive or viscous products, semi-solid, and shear sensitive materials. They require low maintenance and replacement, and have self-priming ability with seal-less design. They are also capable to run dry without causing any damage to the pump.  
 
The best thing about these pumps are: They're manufactured in a variety of materials, including cast iron, stainless steel, special alloys, and various diaphragm and valve elastomers, making them ideal for any industry.
 
Considering the multi-tasking facility of diaphragm pumps, they must be purchased from a reputed pump supplier in Wicklow.
