Electric diaphragm pump is one new kind of pumps, which has been employed in more and more industrialized countries over the world in recent years because of the breakthrough development in its diaphragm materials, it displaces some centrifugal pumps and screw pumps and is used in the trades of chemistry, ceramics, metallurgy and so on, the electric diaphragm pump, which produced in our corporation, is designed in accordance with sampled machine offered by ABEL company (U.S.A), it is suitable for the places with low pressure, i.e., its outlet pressure is less than 3kgf/cm².

DBY has the following characteristics:

1. Water irrigation and diversion are not necessary, its self-suction capacity can reach 7 odd meter.

2. Enjoying excellent passing performance, even can pass through easily particles and slurry whose diameter below 10 mm.

3. The medium must not be leaked because the diaphragm has separated the transmitted medium from transmission machine. Moreover, owing to no shaft seals in the pump, its service life will be greatly prolonged, the diaphragm, according to its medium, can be classified as chloroprene rubber, fluorous rubber and Buna-N rubber to meet the requirements of various customers.

4. The flowing part of pump body for medium can be classified as cast iron, stainless steel, lining rubber in accordance with the requirements of customers, while its motor can be differed from general type and explosion-proof type (B3d).
