Air Operated Double Diaphragm Pumps
-
Product Highlights- It is easy to use, reliable in work, and only needs to open and close the gas valve. even if the pump runs without medium for a long time due to unexpected circumstances or suddenly stops the pump, it will not be damaged. once overloaded, the pump will automatically stop. self-protection performance, when the load returns to normal, it can automatically start operation;
- Pneumatic diaphragm pumps have six advantages: reliable quality, long service life, low noise, low vibration, never crashing, and fine workmanship. they can pump flowing liquids and transport some difficult-to-flow media.
- This pump has simple structure, few wearing parts, convenient installation and maintenance. the medium conveyed by the pump will not touch the moving parts such as the valve, linkage, etc., unlike other types of pumps due to the wear of rotors, pistons, gears, blades and other parts. decrease performance gradually.
