Perspectives: Making it Work

Special Seal Surmounts Latex Problem

Custom design provides a cost-effective long-term solution for pumps

By Jürgen Mews, EagleBurgmann Germany

Preventing problems with mechanical seals used on pumps handling synthetic polymer dispersions (latex) is a major engineering challenge. Essentially, difficulties arise because the polymer dispersions are not thermodynamically stable and tend to coagulate. Polymer particles form compact agglomerates that quickly can bring the process to a halt.
