Plastic material for some chemical principle has good corrosion resistance, so the plastic pneumatic diaphragm pump also known as chemical diaphragm pump or chemical resistant diaphragm pump.Polypropylene pneumatic double diaphragm pump is called plastic pneumatic double diaphragm pump, because of its unique material to its good characteristics: first, relative to the metal pneumatic double diaphragm pump it can help to reduce the weight of the half, greatly strengthened the movement of the diaphragm pump performance; Polypropylene pneumatic double diaphragm pump for conveying liquid containing metal medium has no effect, and for some acidic liquid by better corrosion resistance, for some of the medical unit, chemical unit and gold mine is a very good pump selection;
KY brand enhanced polypropylene pneumatic double diaphragm pump, is our Shanghai Yang pump industry continuously absorb and learn the experience of the imported pneumatic double diaphragm pump is developed a new type of domestic pneumatic double diaphragm pump. Distribution device further innovation, intermediates and every other row of one-piece; Power-assist axis and help move the slider to one-piece production, and increase the slide valve power-assist ventilation device, greatly improving the utilization efficiency of the air, to avoid the crash, because of the air pressure is not stable and downtime; Really do not crash, and automation machinery and equipment to do the seamless connection.



1, Pneumatic diaphragm pump polypropylene material relative density is small, only 0.89-0.91, is one of the lightest varieties of plastics.
2, polypropylene material is qualitative good mechanics performance, in addition to the resistance to impact and other mechanical properties are better than polyethylene, processing performance is good; Polypropylene pneumatic diaphragm pump texture pure, non-toxic, good electrical insulation.
3, polypropylene chemical performance is good, so the plastic pneumatic diaphragm pump also known as chemical diaphragm pump or chemical resistant diaphragm pump.almost no water absorption, and does not react with most chemicals.
4 pneumatic diaphragm pump, polypropylene as he powered by air, and it is destined to his unparalleled safety performance and quiet performance.
5, explosion-proof performance: don't worry about danger because of wire, the engine, in the environment of the inflammable, explosive operation need not take any protective measures, and don't have to worry about there will be noise annoyance;
6, pneumatic diaphragm pumps do not need irrigation water diversion, up to seven meters, suction lift up to 80 meters.
7, can be submerged in the working medium, the water pump no rotating parts and no shaft seal, diaphragm, such as the movement of the pump and pumping medium components, workpiece medium completely separated, the conveying medium will not leak out.
8, pneumatic diaphragm pump pump body to do a variety of material, has good corrosion resistance, suitable for all kinds of medium
9, KY type pneumatic diaphragm pump on integral structure to optimize, the pump cavity and competent road has improved remarkably, self-priming function and flow head has a lot to improve (maximum flow / 54 cubic meters/hour, maximum head 80 meters). Customers to become super flow pneumatic diaphragm pump and filter press special pneumatic diaphragm pump.
10, KY type pneumatic diaphragm pump flow and pressure has greatly enhance not only, also significantly reduce the noise, because KY type pneumatic diaphragm pump all adopt the reverse osmosis filtration core, truly fall the action of the sound without resistance; Because KY brand pneumatic diaphragm pump work for three guide one-piece, its pulse also significantly reduced.

Diaphragm pump body material selection | |||
The conveying medium is medium and weak corroding liquid ,such as oil consumption, rain water, mud water, etc. | |||
The conveying medium is a strong alkaline liquid or a medical one, for food use, such as drinks, milk, chocolate and other liquids, stainless steel diaphragm pump can be used; | |||
The conveying medium is a strong acid type liquid, such as low concentration of sulfuric acid and hydrochloric acid. Polypropylene pneumatic diaphragm pump can be used. | |||
If the conveying medium has a relatively bad working condition, contains strong acid and strong alkali, and the temperature is relatively high, we can choose the inner lining fluorine pneumatic diaphragm pump and fluorine plastic PVDF diaphragm pump. | |||
Diaphragm material selection | |
NRB | Oil: machine oil, diesel oil and other temperatures 0-70 degrees, |
Santoprene | Paint, weak acid and alkali and other special weak corrosive liquid, temperature 0-100 degrees |
PU | Mortar, sludge, and other normal temperature liquids with relatively large wear: |
Teflon or composite diaphragm plate | Corrosion is bigger, exports have pressure, and temperature are: teflon or composite diaphragm plate. |
