FleXeal® mechanical seals


A mechanical seal is a key element in agitated reactors.

Like all rotating parts, it is subject to wear and risks being damaged. This may cause unplanned plant shutdowns, resulting in loss of production and additional costs, which can both cause a reduction in profit.

FleXeal® mechanical seals are the sealing result within Pfaudler’s product portfolio useful for the specific market solutions.

The important areas in Pfaudler’s expertise are the different designs available for wet, dry, contact, and non-contact mechanical seals and a service team dedicated to their maintenance.
