Description
This air-operated diaphragm pump is made of aluminum for greater durability and long life. The large flow rate also saves you time and improves efficiency. The pneumatic feature makes it safer and more reliable. And it is also suitable for construction, petroleum, chemical, pharmaceutical, electric power, and other fields.
Key Features
Diaphragm Pump: The pump without rotating parts, and shaft seal, diaphragm pumping medium in the pump's moving parts, the working medium is completely separated, and the transported medium will not leak out, so when pumping toxic, easy-to-play or corrosive media, will not cause environmental pollution and endanger personal safety.
High Efficiency: The air-operated diaphragm pump has a high head of 69m/ 226.38ft and a sucked lift of 5m/ 16.4ft, which can complete more effective pumping work in a shorter time.
Durable Material: The air-operated diaphragm pump is made of high-quality aluminum alloy, which is strong and rust-proof, more durable, and has a long service life.
Good Sealing: It uses a buna-butadiene rubber ball valve to give it good sealing while providing the best air efficiency to provide you with a better user experience.
User-friendly: This pump has a simple structure and few wearing parts, making it easier to install and maintain than other types of pumps. In addition, it does not need to use oil lubrication, even if idle, there is no effect on the pump, dedicated to providing you with the most convenient user experience.

And it does not require electricity so it can be used safely even in flammable and explosive situations.
Easy to Operate: It does not need to irrigate, and simply opens and closes the gas valve. And its head and flow rate can be steplessly adjusted by opening the gas valve.
Good Applicability: It flows spaciously and has good passing performance, allowing the passage of particles up to 4.5mm/ 0.177in diameter, making it possible to pump a wide range of media.
Low Noise: This pump is equipped with a muffler, allowing it to operate with less noise, so you can have a quiet operating atmosphere.
