What does a diaphragm Pump do?

These pumps, also known double diaphragm, are used in many industries. These pumps are versatile and highly efficient. They can handle all fluids, including food grade clean waters to acids and slurries as well as liquids with high viscosity. Their simple operation and design make them relatively cost-effective.

How they work

Diaphragm Pumps: Uses

A positive displacement pump is a double diaphragm Pump. It works by using two diaphragms, which move in and outside of the pump chamber to fill it with fluid and then push it back out. Fluid rushes in when the diaphragms move out of the chamber. The fluid flows out of the chamber when they push back on the chamber.

The fluids flow through one direction check valves. This ensures that the fluid only flows in the correct direction through the chamber.

Diaphragm Pumps' Work Characteristics

Diaphragm pump's suction lifting characteristics are well-known. The pressure and flow rates will depend on the size of the chamber, diaphragms and their rate. Diaphragm pump can handle slurries as well as sludges. They can deliver discharge pressures as high as 1200bar.

Due to their design, they are very reliable when dry. Because they are very similar to human hearts, artificial hearts can be made from them. They can be self-priming in most circumstances and can be as efficient as 97%. They are able handle most viscous liquids as long they are not too large.

Best uses for Diaphragm Pumps

Because diaphragm pumps can be used for fluid transfer in nearly every industry, they are very versatile. They are used across many industries to dewater or remove water. They are ideal for filling, dispensing or metering due their accuracy and efficiency.

They can provide high pressure for cleaning and spraying, and are used often for filter press applications.
