Magnetic Stirred Reactor
Reaction Equipment

Magnetic Drive Reactor
1. Product Overview
The magnetic drive reactor replaces the conventional mechanical seal with a magnetic coupling drive, providing complete hermetic sealing of the vessel. It consists of a reactor body, a magnetically driven agitator, a heating/cooling system, and a control system, completely eliminating the risk of dynamic seal leakage.
Widely applicable to: Highly toxic material reactions, high-purity chemical synthesis, precious metal catalytic reactions, flammable and explosive medium reactions, aerospace special material preparation, etc.
Equipment features: Zero leakage, extremely high sealing reliability, high-pressure resistance, no cross-contamination, suitable for hazardous media.
2. Working Principle
An external motor drives the outer magnet ring, which through magnetic coupling rotates the inner magnet ring and agitator shaft in sync — no dynamic seal penetrates the vessel wall. Heat-transfer fluid circulated through the jacket controls the internal temperature, while the contents are mixed, dispersed and reacted under agitation. Since there are no dynamic seal points, hazardous gases or liquids inside cannot escape along the shaft into the environment.
3. System Classification
By Magnetic Coupling Structure
| Type | Features | Application Scenarios |
|---|---|---|
| Synchronous magnetic coupling | Inner/outer rings rotate synchronously, no slip | Low viscosity, high speed |
| Asynchronous magnetic coupling | Slip exists, smooth torque transmission | Medium-high viscosity, large torque |
| PM + eddy current braking | Torque limiting function, overload protection | Critical safety applications |
By Pressure Level
| Type | Pressure Range | Application Scenarios |
|---|---|---|
| Low pressure | Atm~1.6MPa | General sealing requirements |
| Medium pressure | 1.6~10MPa | Pressurized hydrogenation, pressurized reactions |
| High pressure | 10~30MPa | Supercritical reactions, high-pressure polymerization |
| Ultra-high pressure | >30MPa | Special synthesis (Customized) |
