Design features
CN MAG-M Magnetic drive pumps are designed to improve people and plant safety. Especially when toxic, explosive or other dangerous liquids which react on contact with the atmosphere are handled. For all these services rear containment shell replaces double mechanical seals with external fluid reservoires and all the required control devices. 

CN MAG-M pumps offer therefore exceptional benefits to the chemical, petrochemical and allied industries.

A wide range of pumps covers the different performances.

RWP QUICK CHANGE CARTRIDGE KIT to guarantee an easy and fast maintenance.

The thrust loads of the closed impellers are totally balanced by back vanes. Minimum residual forces that act in suction flange direction, are beared by strong silicon carbide, spring mounted, thrust bearings.

The Bearing materials available are of three different types to provide the best solution for each application: Silicon Carbide (SSIC), Tungsten Carbide (TC). The Silicon Carbide parts are elastically mounted by tolerance rings, beared and designed for temperatures up to +662 °F (+350 °C) without heat exchanger.

Field assembling of the product lubricated bearing arrangement does not require special tools.

Rear shell is made of one single piece, no welding, ellipsoidal profile that has been studied to withstand higher pressures than the traditional one.

The high performance magnets can operate at liquid temperature of up to 662 °F (350 °C) without external cooling.
