Highlights:
The all-plastic pneumatic diaphragm pump can not only pump flowing liquids, but also transport some difficult-to-flow media. It has many advantages of self-priming pumps, submersible pumps, canned motor pumps, mud pumps and impurity pumps.

1. No need to irrigate and divert water, the suction range is as high as 10m, the head is 70m, and the outlet pressure is ≥6kgf/cm2;

2. The flow is spacious, the passing performance is good, and the maximum particle diameter allowed is 4mm. When pumping mud and impurities, there is little wear on the pump;

3. The head and flow can be adjusted steplessly through the valve opening (air pressure adjustment is between 1-7kgf/cm2);

4. The pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts of the pump and the workpiece medium, and the conveyed medium will not leak out. Therefore, when pumping toxic, easy to play or corrosive media, it will not cause environmental pollution and endanger personal safety;

5. There is no need to use electricity, and it is safe and reliable to use in flammable and explosive places;

6. Can be submerged in the medium to work;

7. Easy to use and reliable in work
To start and stop, you only need to simply open and close the gas valve. Even if the pump runs without medium for a long time or suddenly stops due to unexpected circumstances, the pump will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it can start operation automatically;

8. Simple structure and few wearing parts
The pump is simple in structure, easy to install and maintain. The medium conveyed by the pump will not touch the moving parts such as the built-in valve, linkage, etc., unlike other types of pumps due to the wear of rotors, pistons, gears, vanes and other components. Gradually decrease

9. It can transport relatively viscous liquids (viscosity below 10,000 centipoise);

10. The pump does not need to be lubricated with oil

[The main purpose]
1. Pump peanut butter, kimchi, mashed potatoes, red sausage, chocolate, hops, syrup, etc.;
2. Pump paint, pigments, glue, adhesives, etc.;
3. Pump all kinds of tiles, porcelain, bricks and pottery glaze slurry, etc.;
4. Pump various abrasives, corrosives, cleaning grease, etc.
5. The pump sucks various highly toxic, flammable, and easy-to-use liquids, etc.;
6. Pump various sewage, cement grouting and mortar, etc.;
7. Pump various strong acids, strong alkalis, strong corrosive liquids, etc.;
8. As the front-stage pressure sending device of various solid-liquid separation equipment.
