product overview

Shanghai Shunlong Pneumatic Diaphragm Pump is a new type of conveying machinery and currently the most innovative type of pump in China. Using compressed air as the power source, it can extract and absorb various corrosive liquids, particulate liquids, high viscosity, volatile, flammable, and highly toxic liquids.

Shunlong pneumatic diaphragm pump is made of four materials: engineering plastic, aluminum alloy, cast iron, and stainless steel. Pneumatic diaphragm pumps are made of nitrile rubber/black, three-way rubber/blue, polyether rubber/beige, fluororubber/black, and polytetrafluoroethylene/white according to different liquid media. To meet the needs of different users.
Pneumatic diaphragm pumps are installed in various special occasions to pump media that cannot be pumped by conventional pumps, and have achieved satisfactory results. Absolute fire and explosion prevention, with all functions of submersible pumps, self-priming pumps, impurity pumps, shielded pumps, mud pumps, and many characteristics of conveying machinery.

Application scenarios

Chemical industry, coatings, food, environmental protection, petroleum

Beverage industry, pharmaceutical industry, electronics industry, paint and spray coating.

Reasons for the safety of diaphragm pumps in flammable and explosive environments

Firstly, it is impossible to generate sparks after grounding;

Secondly, there is no heat generated during work, and the machine will not overheat;

Thirdly, the fluid will not overheat because the pneumatic diaphragm pump has minimal agitation on the fluid.

In harsh areas of construction sites, such as construction sites and industrial and mining wastewater discharge, due to the high impurities and complex composition in the sewage, the pipelines are prone to blockage, which leads to excessive load on the electric pump and makes the motor vulnerable to heating. Pneumatic diaphragm pumps can pass particles and have adjustable flow rates, automatically stopping until unobstructed when the pipeline is blocked.

Product Features

1. No need for water injection. The suction lift can reach up to 5m, the head can reach 70m, and the outlet pressure is 6bar.

2. Spacious flow and good passing performance. It allows for a maximum particle diameter of 10mm. When pumping mud and impurities, there is minimal wear on the pump;

3. The head and flow rate can be infinitely adjusted through the opening of the air valve (the air pressure can be adjusted between 1-7 bar);

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

5. No need for electricity. It is safe and reliable to use in flammable and explosive places;

6. Can work submerged in a medium

7. Easy to use, reliable in operation, with simple opening and closing of the gas valve for on-off. Even if the pump runs without medium for a long time or suddenly stops due to unexpected situations, it will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it can automatically start running again;

8. The pump has a simple structure and few vulnerable parts. It is easy to install and maintain, and the medium transported by the pump does not come into contact with moving parts such as the valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of components such as rotors, pistons, gears, and blades;

9. Can transport viscous liquids with viscosity below 10000 centipoise;

10. This pump does not require oil lubrication and has no impact on the pump even when idling, which is the biggest feature of this pump.

11. Easy and economical installation, small size, easy to move, can be used in various occasions, easy maintenance, simple operation, can be turned dry without any damage, does not require any lubrication, and can be remotely controlled.

12. Safe and cost-effective for daily use In the handling of hazardous and corrosive materials, pneumatic diaphragm pumps can completely isolate the materials from the outside world. Or ensure that there are no impurities contaminating the raw materials in some experiments. Can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials, flocculants, etc. This is because the shear force of pneumatic diaphragm pumps is low and has little physical impact on the material.
