Centrifugal Pumps

CombiMag Magnetic Drive Centrifugal Pump


Centrifugal pumps are driven by a motor through a shaft which have to penetrate into the pump chamber. In order to keep the products inside, a seal is needed. This seal often wears off and the product leaks. This is problematic if the product leaked is poisonous or is flammable. Arasains Indonesia supplies the Johnson CombiMag, a centrifugal pump driven by a magnetic coupling. This makes the pump 100% leak free with a long life cycle and reduced maintenance cost. This pump uses the Johnson famous high efficiency impeller. It is suitable for slightly contminated liquids without abrasive or magnetic particles. Maintenance is easy with back pull out principle. Magnets used are Samarium Cobalt high performance magnets. The containment can is made of Hastelloy for limited eddy current losses. Heating jackets can be supplied. Lubrication can be specified for oil or grease. Temperature monitoring with PT 100 are available. The pump impeller has liquid lubricated silicon carbide internal bearings with hardened wear plate.
