Soft-Face Mechanical Seals

MECO seals are soft-face, high-runout, contacting mechanical seals designed for process equipment operating in challenging conditions. Unlike traditional hard-face seals, MECO seals tolerate significant shaft runout and misalignment, operate without lubrication, and eliminate common issues associated with packing and conventional mechanical seals.

Ideal for handling dry powders, pastes, slurries, liquids, and vapours, these seals ensure process integrity and reduce downtime.

Easy Maintenance

Most seals are fully split, allowing quick installation and rebuilding without removing the drive

Long-Lasting & Efficient

Our seals limit friction, abrasion, and excess heat, delivering superior performance compared with traditional mechanical packing

Contaminant Protection

MECO seals create a positive sealing barrier that prevents external contaminants from entering the process, ensuring product integrity and safety

Cost Optimisation

Multiple model variations suit a wide range of application demands, supported by cost‑reduction models designed to improve maintenance efficiency and reduce long‑term operating costs

Design & Performance Features

Soft-face sealing technology eliminates shaft abrasion and high-operating temperatures typical of packing
Wide-radius seal faces accommodate eccentric rotation and misalignment
Non-lubricated seal faces utilise proprietary PTFE-based wear materials for dry-running capability
Handles extreme runout up to 6 mm diametric for flexible operation
Fully split designs simplify installation and maintenance without major plant modifications
Operates on a perpendicular plane, eliminating relative motion for consistent sealing performance
Effective sealing on worn or scored shafts
Resistant to abrasive powders without causing shaft wear

Engineered for your application

Design options include:

Single-face and double-face configurations for varied sealing requirements
Split seals for rapid cleaning and sanitising in hygienic environments
Positive drive with constant spring loading for reliable sealing under dynamic conditions
External springs are isolated from the process for contamination control
Models designed to accommodate thermal growth and axial shaft movement
Handles radial and angular misalignment
Minimal or no plant modification required during installation
