The CDM™seal solved a problem in which the existing single seal was unable to cope with
a pulp density of more than 3%, which meant that the sliding surfaces were not adequately
lubricated. This resulted in multiple seal failures, loss of product, and high repair costs.
The CDM™ double seal was installed in January 2019 and is still working without a problem
after more than five years. Return on investment was achieved in less than four months. The
double seal and barrier system has ensured the efficient lubrication and cooling of the seal
faces, and has prevented the ingress of solids.
A company spokesperson said:
“Thanks to this conversion, we have a safe workplace and no loss of product,
along with significant savings in energy and water costs.”
