AUXILIARY SYSTEMS FOR MECHNICAL SEALS

They simultaneously secure mechanical seal pressurisation, cooling and barrier fluid thermoregulation.

We offer you a comprehensive range with various options depending on the types mechanical seal assemblies in compliance with applicable standards. Lubricated mechanical seals installed on process pumps, reactors or filter-driers are the main areas of use. Our technical teams can install and maintain the equipment on your sites. The equipment is tested and validated at the factory beforehand, thus securing reliable commissioning.

ADVANTAGES

• Suitable for harsh environments
• Maintains the fluid level and pressure in the barrier circuit
• Allows rapid visual check of barrier fluid level in the event of pressure loss
• Optimises maintenance time between interventions
• Increases mechanical seal life
• Ensures environmental and individual protection
