Product Overview
The electric diaphragm pump is a new type of pump. In recent years, due to the breakthrough in the material of the diaphragm, more and more industrialized countries in the world use this type of pump to replace part of the centrifugal pump. Screw pump is used in petrochemical, ceramic, metallurgical and other industries. The design of electric diaphragm pump currently produced by our company is based on the prototype of American abel company. The dby diaphragm pump is suitable for low pressure, that is, the outlet pressure & 3k9f/cm2 .

Performance Features
First, no need to irrigate water, self-priming capacity of more than 7 meters.
Second, through the performance, particles, mud, etc. with a diameter of less than 10 mm can be passed without difficulty.
Third, since the diaphragm will be separated by the conveying medium and the transmission mechanical parts, the medium will never leak outward. Moreover, the pump itself has no shaft seal and the service life is greatly extended. According to different media, the diaphragm is divided into neoprene, fluororubber, nitrile rubber, etc., which can meet the requirements of different users.
4. The flow medium of the pump body can be divided into cast iron, stainless steel and rubber lining according to user requirements. The motor is divided into two types: ordinary type and explosion-proof type.
