• Low Friction: The dry-running carbon formulation generates minimal heat, preventing face damage in gas-phase operation.
• FDA Compliance: Available with FDA-approved dry-run materials for use in food and pharmaceutical mixers.
Key Features
• Agitator Specialist: A modified version of the M3N designed specifically for top-entry mixers, agitators, and reactors where liquid lubrication is not available.
• Dry-Run Faces: Features specialized dry-running Carbon Graphite faces that can operate against Ceramic or SiC without a liquid film.
• Vapor Sealing: Effective at sealing vapors and gases in the head-space of mixing vessels.

Industry Solutions
Case Study
Powder Blender: A food powder blender's top seal was leaking dust. Liquid seals made a mess. We installed this Dry-Running M3N. It sealed the dust inside the vessel without needing any oil or water lubrication.
Testimonials
Finally a simple solution for our top-entry mixers. No more messy oil pots, just a dry-running seal that works.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Can I use a standard M3N for dry running?
A: No! Standard M3N faces require liquid lubrication. Running them dry will destroy them in minutes. You must specify the "Dry Running" version with specialized carbon faces.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
