In chemical processing, seal integrity is directly tied to worker safety and environmental compliance. A chemical manufacturer faced frequent leaks from rotary pump systems handling corrosive media, prompting an urgent need for a more robust sealing solution.

Application Background

The pumps handled sulfur-based compounds under pressure and fluctuating temperatures. Previous seals showed signs of chemical degradation and failed after just 4–6 months, posing leakage risks and triggering emergency shutdowns.

COMBI Custom Engineering

COMBI developed a tailored sealing system using chemically resistant elastomers and a multi-barrier lip design. The system included a back-up safety lip for redundancy and a PTFE coating for thermal stability and low friction operation under dynamic loads.

Results from Implementation

After deploying COMBI seals across the plant, the client reported zero leakage over 16 months of continuous operation. Seal integrity was validated during quarterly inspections, and pump servicing frequency dropped from bi-monthly to semi-annual intervals.

Customer Statement

The plant’s lead maintenance technician said: “COMBI delivered not just a product, but peace of mind. Our containment has improved, safety risks have dropped, and we’re spending significantly less on emergency responses.”
