Diaphragm pumps are actually embolic pumps, which separate the transported liquid from the live column and pump cylinder by means of a membrane, thereby protecting the live column and pump cylinder. The parts on the left side of the diaphragm that are in contact with the liquid are made of corrosion-resistant materials or coated with a layer of corrosion-resistant materials; the right side of the diaphragm is filled with water or oil.

Features:
1. There is no shaft seal, no leakage, and spacious flow path, so when conveying particles containing particles, high viscosity (viscosity up to 10,000 centipoise), volatile and corrosive media, it will not cause environmental pollution and endanger personal safety.
2. No rotating parts, good passing performance, the maximum particle diameter allowed is 10 mm. There is no shear flow of the liquid, and the parts of the pump wear little. It has little damage to the conveyed material, and can convey sludge and living organisms such as small fry.
3. No need to irrigate water, strong self-priming ability, suction range up to 7 meters, long time dry breathing, no damage to the pump. Once overloaded, the pump will automatically stop, when the load returns to normal, it can automatically start to run, with self-protection function (electric pump does not have this function).
4. The head of the pneumatic pump is up to 50 meters, the electric pump is up to 30 meters, and the maximum outlet pressure can reach 0.6 MPa. Electric pumps do not have this function, and the inlet needs to be controlled by a regulating valve.
5. The pneumatic pump can be immersed in the medium to work, without power supply, safe and reliable (electric pump does not have this performance).
6. Pneumatic pump does not need power supply and is more suitable for medium transportation in flammable and explosive occasions.
