The medium being pumped runs via the suction chamber into the impeller and is conveyed by the impeller to the discharge nozzle. The slide bearings are lubricated and the rotor compartment is cooled via the partial flow which has been taken from the main pump flow and which is returned to the main flow after moving through the hollow shaft and the containment shell back to the discharge side. Additional radial borings on rotor end serves to overcome the hydraulic losses encountered along the way. The partial flow return to the discharge side means that there is always sufficient reserve pressure available from the boiling point curve of the medium being conveyed when the heated motor cooling flow returns to the pump. This model of pump can be used forliquefied petroleum gases as well when the same conditions are available. 

DesignThe construction and ratings scheme of the pumps conform to EN 22858 / ISO 2858 / ISO 5199 and have a permanent magnetic coupling as an integral component. The requiredoutput is transferred to the pump via a conventional standard three phase current motor of type B 3 or B 35 with the corresponding intermediate coupling.

Application sectorFor the delivery of aggressive, toxic, explosive, precious, inflammable and slightly volatile fluids.

Application rangesMCNF: –40 °C to +220 °C (350 °C)*Magnetic driveThanks to the use of new types of permanent magnetic materials with high energy density, it is possible to house a powerful magnetic coupling within the pump bearingsupport specified in the standard. The magnetic drive is equipped for direct activation when operated using standard three phase current motors and does not require any type of coupling. In addition, the permanent magnets are highly stable against demagnetising effects, such as those which may occur when assembling or disassembling the rotor or if the maximum transmittable torque is exceeded.
