Roten PTFE Wedge Mechanical Seals for Reactor

• Chemical Inertness: The switch to a PTFE wedge allows standard Roten-style seals to operate in fluids that would destroy NBR or EPDM rubber.

• Short Working Length: Designed to fit shallow stuffing boxes without modification to the reactor flange.

Key Features

• Chemical Reactor Upgrade: A specialized replacement for Roten-style mechanical seals used in European chemical reactors and mixers.

• PTFE Wedge Technology: Incorporates a PTFE wedge secondary seal instead of rubber bellows, providing chemical resistance to aggressive solvents, acids, and varying temperatures.

• Compact Profile: Fits into the limited space often found in top-entry mixer sealing housings where standard cartridge seals won't fit.

Case Study

Chemical Synthesis: A batch reactor producing API (Active Pharmaceutical Ingredients) used Roten seals that leaked after solvent cleaning cycles. We supplied this PTFE Wedge version. The wedge resisted the solvent wash, preventing batch contamination.

Testimonials

We have many Italian-made reactors. These replacement seals fit perfectly and the PTFE wedge handles our solvent washes much better.

FAQs about Metal Bellows Seals for High Temperature Pumps

Q: Is this a cartridge seal?

A: Typically no, standard Roten seals are component seals. However, we can engineer a cartridge version if you want easier installation. This specific product is a component replacement.
