Many industries use double diaphragm pump, also known as dialypsm pumps. They are extremely versatile and efficient, and can handle fluids from clean water to acids to slurries to food grade clean water. Because of their simplicity and ease of use, they are very affordable.
How they work
Uses for Diaphragm pumps
Positive displacement pumps are double diaphragm pumps. The pump uses two diaphragms to fill the chamber with fluid, and push it out. The chamber's pressure is lower when the diaphragms are moved away from it. Fluid then rushes into the chamber. They push back into the chamber to increase the pressure, and fluid flows out.
Fluids flow through one way check valves to ensure that they only flow in the correct direction throughout the chamber.
Diaphragm Pumps Work Characteristics
The suction lifting properties of diaphragm pumps is what makes them so popular. The chamber's size and the flow rate of the diaphragms will determine the pressure and flow rates. Diaphragm pumps are capable of handling slurries or sludges. They can discharge up to 1200 bar.
Because of their design, they have excellent characteristics for running dry. They are used to produce artificial hearts because they have a similar action to a human heart. They can self-prime in almost all situations and can achieve 97% efficiency. They are able to handle even the most viscous liquids, provided they don't become too big.
Uses of Diaphragm Pumps
They are versatile and can be used in almost any industry that requires fluid transfer. They are used in many industries for water removal and dewatering. Because of their accuracy and efficiency, they are often used to fill, dispense and meter.
These units can create a lot of pressure for cleaning and spraying applications. They are also used in filter press applications.
