Certified for use in Zone 0*. Examples of suitable liquids: acetone, alcohol, ammonia, petrol, flammable solvents, nitrocellulose varnishes, perchlorethylene, trichlorethylene, toluene, potassic alkali, soda alkali, phosphoric acid (up to 60%), sulphuric acid (up to 75% and more than 96%), fruit juices, milk, salad oil and all liquids listed for aluminium alloy. | | | | | | 'Zone 0 Area in which a hazardous and explosive atmosphere of gases, vapours or fogs exists permanently or for a long period of time. In general such conditions exist inside of barrels or containers only. The following pump models are tested and certified according to Directive 94/9/EC-ATEX 100a, category 1/2, for transferring high flammability liquids out of portable barrels or containers in hazardous areas Zone 0: F 424 S - EC Type examination certificate PTB 00 ATEX 4108 X F 425 S - EC Type examination certificate PTB 99 ATEX 4001 X F 426 S - EC Type examination certificate PTB 00 ATEX 4109 X F 430 S - EC Type examination certificate PTB 00 ATEX 4110 X F 430 HC - EC Type examination certificate PTB 00 ATEX 4110 X | | | | | | | | | | Hastelloy C (HC) up to 120°C Specially designed for pumping alternatively high flamma bility and chemically aggressive liquids. Certified for use in Zone 0*. Examples of suitable liquids: hydrofluoric acid, aqua regia, oleum, hydrochloric acid (up to 30%), sulphuric acid, various mixed acids and all liquids listed for aluminium alloy and stainless steel. Aluminium alloy AlMg5 (AL) up to 100 °C Suitable for neutral, low flammability liquids. Examples of suitable liquids: drilling emulsion, diesel oil, fuel oil, hydraulic oil, non-flammable solvents, liquid soap, liquid wax, water. | | | | | | | | | | Bold and italic printing of liquids indicates that the standard o-ring fitted FKM is not sufficiently resistant to this liquid. (Please consider when selecting the pump design.) P.S.: Due to the enormous variety and complexity of industrial chemicals, together with the range and variation of FLUX products, we can only list some of all the suitable liquids. But we would be glad to send you a detailed Resistance Chart. | | | | | | | | | | | | | | Polypropylene (PP) up to 50 °C Suitable for both, chemically aggressive and neutral liquids, together with low flammability liquids such as acids and alkalis. Examples of suitable liquids: formic acid, ammonia, boric acid, chromic acid (up to 10%), liquid fertilizers, acetic acid, photo developers, hydrofluoric acid (up to 70%), fruit acids, potassic alkali, copper chloride, lactic acid, soda alkali, phosphoric acid, hydrochloric acid, sulphuric acid (up to 80%), distilled water. | | | | | | | | | | Polyvinylidenfluorid (PVDF) up to 100°C Suitable for both, chemically aggressive and neutral liquids, together with low flammability liquids such as acids and alkalis. Examples of suitable liquids: hydrobromic acid, chromic acid, chloric acid, hydrofluoric acid, sodium hypochlorite, nitric acid (up to 75 %), sulphuric acid and all liquids listed for polypropylene (except soda alkali). | | | | | | | | | | | | | | | | | | | | | | |
