Sectors we support

Seal Solutions for all Pharmaceutical Brands

Precision and hygiene without compromise

Pharmaceutical systems demand consistent, sterile, high-purity performance. Seal failures risk batch loss and compliance issues.

We engineer seals that survive aggressive CIP/SIP cycles, stand up to any chemical make up and deliver predictable performance.

Seals for pumps, mixers and agitators

We support for all seal types, whether its Fristam, Hilge, APV, Waukesha, Alfa Laval or any other brand we can help.

Our seals maintain stability and cleanliness across sterilisation and solvent-heavy duties.

Refurbishment Service

Pump, mixer and agitator refurbishment

Performance drift often happens before seal leakage. 

We restore equipment to precise, compliant condition with new components, corrected tolerances and fully lapped faces.

Refurbishment typically costs around 50 per cent less than new equipment.

Seal refurbishment

We refurbish any pharmaceutical-grade seal including double seals, cartridge seals and component seal designs.

A refurbished seal performs exactly like new and costs around 50 per cent less.

ATEX-Rated Sealing solutions

We supply seals certified to ATEX Category 2 for Zone 1 and Zone 21 where solvents and powders create hazardous zones.
