Reliable,leak-free pumping of hazardous fluids with sealless mag-drive pumps

摘要

Suited to pumping clean liquids without solids in the chemical and petrochemical industries,Dickow SCM pumps can handle capacities up to 37 m~3/hr on fluid handling systems with differential heads to 400 metres and liquids at temperatures up to 1 80°C.They have a maximum operating pressure of 40 Bar,although a high system pressure option is available for applications with pressures up to 110 Bar.They are also suited to priming suction lines after filling.The magnetic coupling and static containment shell design of these pumps results in a closed system which eliminates the need for double acting mechanical seals,external fluid reservoirs and any associated control equipment.With around 90% of pump failures caused by leaking mechanical seals,the sealless design brings the benefits of reduced costs associated with unscheduled repairs and maintenance caused by failing mechanical seals and therefore reduces the overall costs of ownership.The single elements of the multipolar magnet coupling elements are completely encapsulated and not in contact with liquid and are made from Cobalt-Samarium for unlimited lifetime durability.Power is transmitted to the hermetically sealed liquid end by a bank of external magnets with the inner and outer magnet rings locked together by magnet forces which work as a synchronous coupling.
