Diaphragm is a new type of conveyor can transport all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid.
         Diaphragm pump has four of its material: plastic, aluminum, cast iron, stainless steel.

        Diaphragm under different liquids were used NBR, chloroprene rubber, fluorine rubber, PTFE, poly ethylene 46. To meet the needs of different users. Placed in a variety of special occasions, for pumping of conventional pump suction should not the media, both with satisfactory results.

         In painting, ceramics in the diaphragm has a dominant position absolute, while in some other industries, such as environmental protection, wastewater treatment, construction, sewage, Fine Chemical is expanding its market share, and have the other pump can not be replaced status. Pneumatic diaphragm pump has the advantage of being:

1, because of air to make power, so with the back-pressure flow （exports resistance） automatically adjust to changes, suitable for middle-and high-viscosity fluid. The point is that is the job of centrifugal water benchmarking best, if used for higher viscosity fluids, the necessary supporting reducer or VVVF costs are greatly increased, the gear pump is the same.

2, in the explosive environment pneumatic pump with reliable and low cost, such as fuel, gunpowder, explosives, transmission, because: first, after the grounding could not produce sparks; Secondly, the job is no heat generated, the machine not overheating; Third, the fluid does not overheat because of the fluid stirred diaphragm minimum.

3, at the site of the worst places, such as construction sites, industrial wastewater discharge, because of the sewage of many impurities and complicated, easy to plug the pipe, so that the load on the pump is too high to form the situation, the electrical heating vulnerability. Pneumatic diaphragm pumps and flow through the particles adjustable, pipe plug to open automatically when to stop.
 
4, diaphragm pumps can be used to transport the chemical nature Unstable fluid, such as: photographic materials, such as flocculation liquid. This is because the diaphragm shear stress is low, the impact of small physical Materials.

5, there is harm in the diaphragm, corrosive materials processing, the diaphragm can be compley separated from the material with the outside world.

6, diaphragm, or a number of tests to ensure that no contamination of raw materials.

     In addition, the diaphragm are small easy to move, Do not need foundation, or the ground is extremely small, easy to install the economy. Materials can be used as portable pump.
