Selection and classification of diaphragm pump

 With the development of the times, there are more and more types of pumps, diaphragm pumps are a new type of pump. Diaphragm plastic pump is a volumetric pump caused by the reciprocal deformation of the diaphragm volume change it is used in many scenarios, many modern industrial sectors will be used diaphragm pump. This article will do a brief analysis of the Selection and classification of diaphragm pump, I hope it can bring you help.

The common categories of diaphragm pumps.

 

Diaphragm pump according to the mode of operation, can be divided into three main pneumatic, electric, liquid-operated. Cheerful words, they are pneumatic diaphragm pumps with compressed air as the power source, electric diaphragm pumps with electricity as the power source, electro-hydraulic diaphragm pumps powered by the pressure of the liquid medium. In addition, the diaphragm pump shell selected materials are aluminum, cast iron, stainless steel. Before buying a diaphragm pump, we recommend understanding the working characteristics of different types of diaphragm pumps.

 

How to select a diaphragm pump?

 

·Consider durability

Wear resistance When the fluid medium is a suspension containing a high concentration of abrasive particles, the spool and seat joint surfaces are subject to severe friction every time they close. Therefore the flow path of the valve should be smooth and the internal material of the valve should be hard.

 

·Consider corrosion resistance

Corrosion resistance because the medium is corrosive, in the case of being able to meet the regulatory function, try to choose a simple structure valve, which is also to facilitate the installation and maintenance.

 

·Select the corresponding valve body

Diaphragm pump valve body type selection valve body selection is the most important link in the selection of stainless steel diaphragm pumps. There are many types of diaphragm pump valve bodies. Therefore, we need to carefully analyze the media, process conditions and parameters of the control process, collect enough data to understand the requirements of the system for the diaphragm pump in order to purchase the corresponding diaphragm pump.

 

These are the main recommendations for diaphragm pump selection. In addition, when choosing a diaphragm pump, corrosive liquids according to the degree of corrosion, choose stainless steel, plastic or fluorine plastic material.

 

Why diaphragm pumps can be used in flammable and explosive environments?

 

Diaphragm pumps can be used in flammable and explosive environments because of the special physical properties of diaphragm pumps. First, the air operated diaphragm pump is not likely to produce sparks after grounding. Second, diaphragm pumps work without heat generation, the machine will not overheat. The fluid does not overheat because the diaphragm pump has minimal fluid stirring. In short, in the handling of hazardous and corrosive materials, the diaphragm pump can be completely isolated from the outside world.

 

After going through the above information, do you have a further understanding of the bolster pump? Diaphragm pump is a new type of conveying machinery, using compressed air as the power source, suitable for various corrosive liquids. Our company produces various models of bolster pumps. Shanghai Sotuo Pump Co., Ltd. is a professional pump supplier integrating pump development, manufacturing, sales and service. Our company has strict quality control for each embolism pump, and we hope to bring you the best service.
