Reactor Overhead Stirrer with Sealed Drive

带密封驱动的反应釜顶置式搅拌器

Jacketed glass reactors and autoclaves need agitation without leaks under vacuum or pressure. This drive uses a PTFE mechanical seal or magnetic coupling, holds down to 5–10 mbar abs or up to 6 bar depending on seal, and suits 1–100 L vessels. Shafts are PTFE-coated or 316L. Send your reactor neck size and temperature range.

Speed range: 20–1,500 rpm
Max torque: 50–300 N·cm
Seal type: PTFE mechanical seal or magnetic coupling
Vacuum capability: Down to 5–10 mbar abs
Max working pressure: Up to 6 bar (seal dependent)
