CQB-F type fluorine plastic magnetic drive pump

Product Overview 
CQB-F type fluoroplastic magnetic drive pump adopts magnetic coupling transmission, and there is no dynamic sealing point. Therefore, the phenomenon of running, running, dripping and leaking at the shaft seal of the general shaft transmission centrifugal pump is completely eliminated. Its over-current components are made of fluoroplastic industrial ceramics, which have excellent corrosion resistance and sealing properties, no aging, no toxin decomposition and so on. The transmission power of 3kW or less or less than DN50mm is a perfluoroplastic magnetic drive pump.  
 
Product Features 
The magnetic pump is compact in structure, beautiful in appearance, small in size, low in noise, reliable in operation, and easy to use. The pump body is fixed with metal material, so the pump body is sufficient to support the weight of the pipe, and it is convenient to use and maintain. Flow rate: 1.8-100m3/h Head: 8-32m Power: 0.12-22KW Applicable temperature: -20~100°C 
 
Product usage 
Contains no solid particle corrosive liquid, strong acid, strong alkali, ethanol, bleach, photographic liquid, nitric acid, hydrochloric acid, hydrofluoric acid, acetic acid, sodium hydroxide, acetone, tetraethoxyethane, sea water, salt water, etc.
