O Ring Alumina/Ceramic Mechanical Seals for Mixer

O Ring Alumina/Ceramic Mechanical Seals for Mixer

• Dry-Run Tolerance (with Carbon): When paired with Carbon, the Alumina face handles the intermittent dry running often found in batch mixing processes better than SiC/SiC.

• Chemical Inertness: Alumina Ceramic is inert to most acids and food products, making it ideal for food and chemical mixing tanks.

Case Study


Food Mixing Tank: A food plant mixer was leaking product. We installed this Alumina/Carbon seal with FDA EPDM O-rings. The ceramic resisted the acidic fruit mix, and the seal handled the shaft wobble, ensuring a hygienic process.

Testimonials


Simple, rugged, and food-safe. These ceramic seals are perfect for our batch mixing tanks.

FAQs about Metal Bellows Seals for High Temperature Pumps


Q: Can ceramic handle mixer vibration?

A: Alumina Ceramic is strong but brittle. For mixers with extreme vibration, we recommend upgrading to Silicon Carbide. However, for standard agitation, our O-ring mount provides enough damping for Ceramic to work reliably.
