    Compressed air as a driving force, no spark, static electricity, and electromagnetic interference, can be directly used for flammable and explosive places. It takes the air as momentum which compressed by air compressor. The pump use air out of compressor as the driving force, adjust the air to drive the diaphragm, aim to reach an transport of fluid. The overall structure of the QDM-901 is more optimized, the pump chamber and the main road are significantly strengthened, and the selfpriming function and flow head are greatly improved.


    1. Air power safe. Because it is using air as power, the diaphragm pump does not heat and produce sparks; suitable for use in flammable and explosive environment.

    2. Special material diaphragmDiaphragm is made of corrosion resistant material, can transport a variety of corrosive medium.

    3. Easy installation. Diaphragm Pump is small, light and easy to move. Low failure rate, easy to install and convenient maintenance.

    4. Long life. The pump shell is made of high quality material, internal parts are made of stainless steel and copper, of all those make the pump light, beautiful, stainless and anticorrosive.

    5. Widely use. The liquid can be conveyed by diaphragm pump is wide, the viscosity from low to high, from corrosive liquid to viscous liquid.



    1. Suitable for the transportation of high, medium and low viscosity various acids, bases and corrosive fluids, benzene, ketones, esters and other solvents in chemical industry. The range of flow and pressure adjustment is wide because compressed air is used as power.

    2. Applicable to the transportation of all kinds of fluids in the flammable and explosive environment, because the pneumatic diaphragm pump of kai Yang brand does not generate electric spark in the work, and does not generate and accumulate heat;

    3. It is suitable for conveying all kinds of precious liquid, high harm, high corrosiveness and other dangerous materials in fine chemical industry. Because there is no dynamic sealing structure of the pneumatic diaphragm pump of kaiyang brand, it is completely separated from the outside world, and there is no material leakage;

    4. Suitable for harsh working conditions, such as waste water containing solid particles in oil fields, mines and construction sites, without blockage, overload or leakage of electricity;

    5. Suitable for conveying various materials in portable and mobile situations, without foundation, with small footprint and simple and economical installation



    1 The pump must be mounted vertically, pay attention to the direction of the arrow.

    2 Connect hose to the ink port.
