Sanitary Diaphragm Valve is usually made of five materials, including plastic, aluminum alloy, cast iron, stainless steel, and Teflon. Diaphragm pumps made of various materials are used to pump various media to meet the needs of various working conditions.
Diaphragm pumps have many advantages of their own. Diaphragm pumps do not need to be filled with water when used. The suction head is up to 5m, the head is up to 70m, and the outlet pressure is ≥6bar. The flow is spacious and the passing performance is good. The diameter of the particles allowed to pass is up to 10mm. Pumping mud and impurities every day will cause little wear to the pump; its head and flow rate can be adjusted steplessly through the opening of the gas valve. The pump has no rotating parts, no shaft seal, and the pumped medium such as the diaphragm is completely separated from the moving parts of the pump and the workpiece medium, and the transported medium will not leak out. Therefore, when pumping toxic, explosive or corrosive media, it will not cause environmental pollution and endanger personal safety; it does not generate electricity, so it can be used in flammable and explosive places, safe and reliable; and it can work immersed in the medium. The pump body is easy to use, reliable in operation, and the start and stop only need to open and close the gas valve. Even if the pump runs without medium for a long time or stops suddenly due to unexpected circumstances, it will not be damaged. Once overloaded, the pump will automatically stop and has self-protection performance. When the load returns to normal, it can automatically start running again; the pneumatic diaphragm valve produced by Hongdong Pump Industry has a simple structure and few vulnerable parts. The pump has a simple structure and is easy to install and maintain. The medium transported by the pump will not contact the distribution valve, connecting rod and other moving parts, unlike other types of pumps that gradually decline in performance due to wear of rotors, pistons, gears, blades and other parts. It can also transport more viscous liquids and the pump does not need to be lubricated with oil, and even idling has no effect on the pump.

Customers often encounter various problems when using pneumatic diaphragm valves. So if the air valve of the pneumatic diaphragm valve is frozen, how to solve it?

1. Check whether the water content of the compressed air is too high and install air drying equipment

2. Bubbles are generated at the outlet of the pump:

3. Check whether the diaphragm is broken and whether the clamp is locked, especially the inlet pipe clamp.
4. The product flows out from the air discharge port:

5. Check whether the diaphragm is broken, and whether the diaphragm and the inner and outer clamps are clamped on the shaft

6. The valve makes a rattling sound: increase the outlet or inlet head.
