Description KF 0 – a pump for process engineering. In numerous technical processes dosing liquids is the focus of the task. PUR components, softeners, re-sins, lacquers, paints are just some of the most impor-tant liquids with a broad application range. The accuracy, evenness and reproducibility with which these products can be processed are also decisive for the quality of the final product. The gear pump size KF 0 is especially suitable for these applications.The KF 0 is an external gear pump with flow rates of 0.5 cm3/rev to 4 cm3/rev. The grading of the total of 8 nominal sizes makes it easier...

Gear Pumps KF 0 with magnetic coupling Gear Pumps KF 0 with magnetic coupling Description 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...
