Pumps sealed with a magnetic coupling are used for pumping corrosive, toxic or inflammatory liquids as well as liquids containing particles. Sealed pumps with magnetic clutch are made of polypropylene (PP) or PVDF (PVDF) depending on the area of application. Pumps in this series can apply to pumping liquids such as formic acid, ammonia water, boric acid, fertilizer solutions, acetic acid concentration up to 80%, photographic developers, fruit juices, caustic potash, lactic acid, caustic solution sodium, phosphoric acid, soap solution, water, citric acid, ammonia, chromic acid (up to 10%), liquid fertilizers, photodevelopers, hydrofluoric acid (up to 70%), fruit acids, potassium alkalis, alkaline soda, copper chloride, lactic acid, phosphoric acid, hydrochloric acid, sulfuric acid (up to 80%), distilled water, caustics potassium, methylene chloride, lactic acid, sodium hydroxide solution, caprylic acid, perchlorethylene, nitric acid, hydrazine and others.
