Single-stage canned motor pumps CN/CNF/CNK
Home Industrial equipment Pumps Pumps for aggressive fluids Canned motor pumpsCN, CNF, CNK - single-stage canned motor pumps according to EN 22858 and ISO 2858. Canned motor pumps are characterised by a compact, integrated unit without mechanical seal. The motor and pump form a unit with the rotor and the impeller fitted onto a common shaft. Canned motor pumps always ensure highest safety level when conveying dangerous, toxic, explosive and valuable media.
CN series pumps are used for the delivery of aggressive, toxic, explosive, precious, inflammable, radioactive and slightly volatile fl uids e.g. sulphuric acid, nitric acid, hydrofl uoric acid, hydrocyanic acid, ethanoic acid, formic acid, NaOH, KOH, D2O solvent, etc.
CNF series pumps are sued for pumping liquid gases, e.g. ammonia, freone, carbon dioxide, amines, propane, butane, vinyl chloride, ethylene oxide, chlorine, phosgene, propylene, carbon bisulphide, hydrocarbon, diphenyl (> 250 °C) etc.
CNK series pumps are used for the delivery of hot organic heat transfer oil, as well as heat bath liquids. These models can also be used for aggressive, toxic, explosive, precious, infl ammable, radioactive and slightly volatile fluids.
