A leading manufacturer of viscose special fiber, for use in medicine, for textile and hygiene applications or for special paper, was looking for a reliable pump for conveying viscose. Technical problems of the gear pump used frequently led to delays in the production process. The new Börger pump is equipped with a single-acting mechanical seal with O-rings made of fluoroelastomers. A quench chamber filled with hydraulic oil lubricates the mechanical seal and dissipates any developing heat from the seal. Air cannot come into contact with the seals due to the quench reservoir. Thus, crystallization of the viscose is not possible.
