Problem
Slurries consisting of a suspension of abrasive particles in a liquid medium provide a particularly arduous operating environment for mechanical seals.

Objectives
To improve seal reliability and ruggedness.

Approach
BHR Group worked with an end user, a pump manufacturer, and a seal manufacturer to optimise the sealing arrangement for unflushed slurries. Field conditions, including frequent stop/starts and throttled suction, were replicated, resulting in a seal capable of tolerating very adverse conditions.

Outcome/Benefits
The arrangements developed have been adopted for production with considerable success.
