Transfer gear pump with magnet coupling KRACHT

With various applications conventional seals come up against their limits. Typical applications can be found in PUR plants, refrigerating installations and vacuum plant. It is possible to fit the KF 0 with a magnetic coupling for these applications. The magnetic coupling serves as a shaft seal and to
transmit the torque. The outer rotor of the magnetic coupling is placed on the motor shaft and the inner rotor directly on the pump shaft. The torque is transmitted between the outer and inner rotors through the magnetic forces. The split case, which seals the pump hermetically, is located between the two rotors. The magnetic coupling is used if an absolutely tight seal is required between the pump chamber and the atmosphere, e. g. for dosing isocyanate, where contact with the air would lead to an undesired hardening of the medium. It can be used in vacuum operations, e.g. filling brake liquid, and reliably prevents air penetrating into the system. Non-leak operations are also guaranteed when used in sealed systems with a high admission pressure on the pump suction side. The magnetic coupling is predestined for dosing hazardous and harmful media.
