Air-Operated Aluminum Diaphragm Pump QBK-25 CE

6.It can be soaked in medium.

7.It's convenient to use and reliable to work. Only open or close the gas valve body while starting or stopping. Even if no medium operation or pausing suddenly for long time because of accident matters, the pump will not be damaged caused by this. Once over loading, the pump will automatically stop and possesses the self protection function. When the load recovers normally, it also can start automatically.

8.Simple structure and less wearing parts. This pump is simple in structure, installation and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever etc. Not like other kinds pumps, the performance will drop down gradually because of the damages of rotor, gear and vane etc.

9.It can transmit the adhesive liquid(the viscosity is below 10000 centipoises).

10.This pump needn't the oil lubricant. Even if idling, it has any influence to the pump. This is a characteristic of this pump.

An air operated diaphragm pump designed for simplicity in operation and maintenance. Safe for use in explosive environments. The Metal pump lines provides the durability, chemical resistance, abrasion resistance, and temperature range required for a variety of process and waste applications. The standard material combination is composed of aluminum casing and neoprene diaphragm, balls and valve seat for general purpose non aggressive applications such as in oil and petroleum based fluids. Cast iron, 316 stainless steel and hastelloy casing materials are available as well.

QBK is coosai's new developed series of AODD pump which is also the third generation, it has the virtue of long service life and nonstop operation, not only it can convey some uneasy flowed medium, with the merits the merits of self-pumping pump, diving pump, shield pump, slurry pump and impurity pump etc.

Note: When the air operated diaphragm pump works, install the air filter to leach the moisture form the compressed air, and install the manometer at the outlet of pump, so to avoid damaging as too high pressure, when the pump doesn’t need work, please clean it in time to prevent from concreting

Application :

The diaphragm pumps are driven with compressed air without the need of electric power. Widely used for leak proof applications in industries like petrochemical chemical metallurgy and ceramics etc. Applicable to liquids of leaky corrosive inflammable and explosive & hazardous properties
