KY50LL enhanced aluminum alloy pneumatic diaphragm pump is a new efficient pneumatic diaphragm pump developed successfully by improving the motor structure of pneumatic diaphragm pump in Shanghai kaiyang pump industry. The intermediate of KY enhanced pneumatic diaphragm pump and the septum are integrated. The supporting shaft and the supporting slide block have been changed into one-piece production, which greatly improves the air utilization efficiency and avoids the crash and shutdown caused by unstable air pressure. Truly achieve the characteristics of non-crash, high efficiency, strong suction and automatic mechanical equipment to achieve seamless connection. Widely used in pharmaceutical, sewage treatment, food, chemical, automobile, paint and other industries. The KY enhanced pump is made of cast iron, aluminum alloy pneumatic diaphragm pump, stainless steel 304, stainless steel 316L, fluorine plastic PVDF, polypropylene, etc. The diaphragm is made of mountain road rubber and teflon.
Aluminum alloy pneumatic diaphragm pump for other metal pneumatic diaphragm pump weight can be reduced by about half, as long as there is a gas source, air pipe to aluminum alloy pneumatic diaphragm pump intake valve, it can work. , showing the superior mobility of diaphragm pump; The over-flow pump body of aluminum alloy pneumatic diaphragm pump is made of aluminum alloy, free from rust and pollution, which greatly protects the cleanliness of medium. It is an excellent choice for some medical units, food processing enterprises and beverage industry.



1. The over-flow pump body of aluminum alloy pneumatic diaphragm pump is made of aluminum alloy, which is rust free and pollution-free and greatly protects the cleanliness of conveying liquid.
2. Compared with other metal pneumatic diaphragm pumps, its weight can be reduced by half
3. The aerodynamic pump is powered by air, which ensures its unparalleled safety and quiet performance.
4. Don't worry about the danger caused by wires and engines, and don't take any protective measures when operating in flammable and explosive environment, not to mention the annoyance of noise;
5. The KY aluminum alloy pneumatic diaphragm pump does not generate electric spark or generate and accumulate heat during operation
6. KY pneumatic diaphragm pump has no dynamic seal structure and is completely separated from the outside world, with absolutely no material leakage
7. KY aluminum alloy pneumatic diaphragm pump does not need lubrication, and there is no worry about lubricant contaminating materials
8. The shear force of aluminum alloy pneumatic diaphragm pump on materials is extremely low and does not damage the structure of materials
9. The overall structure is more optimized, with obvious enhancement of self-absorption function and flow head
10. Arbitrary stepless speed change, arbitrary adjustment of flow can be made at the output end without additional device
11. It can deliver complex media such as viscosity and particles

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 | |
NBR | 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 |
Polyurethane | Mortar, sludge, and other normal temperature liquids with relatively large wear |
PTFE or composite diaphragm plate | It is highly corrosive, with the temperature between -10 and 120 degrees, and the temperature will change: |
