  4. Magnetic Agitators and Stirrers

Magnetic agitators and stirrers are used frequently in simple thin-walled laboratory testing vessels and reactors by chemists worldwide. Our engineers designed and developed an advanced range of high pressure testing agitation and mixing systems; utilising a leak-free magnetic coupling that negates the use of rotary seals.

Our compact design incorporates an inner magnetic stirrer assembly; held within a statically sealed housing. The stirrer is driven by an outer magnetic drive assembly, which is in turn driven by an in-line or belt drive motor. Variable speed control and the use of hi-torque motors ensure we can guarantee the precise level of agitation (or mixing) for fluids with various viscosity levels.

The use of cleverly engineered high-energy grade Samarium Cobalt (SmCo) magnets ensures the design is as compact as possible, whilst break-out torque remains extremely high; even at extreme temperatures.

Our magnetic agitation and mixing systems are ideal for test environments (e.g. the agitation of high temperature, high pressure sour gas H2S in high pressure, high temperature applications) that use aggressive chemicals at high temperatures; all internal wetted materials are manufactured from exotic stainless steel.

Applications and Customer Uses

Magnetic agitator drives used within agitation systems are very popular with customers who work within the subsea, energy and materials research sectors.

For customers who deal with stringent subsea testing demands, these drives are used in agitation systems; creating turbid sand and silt seawater environments, whilst conducting wet-mate electrical connector testing (mate/ de-mate functionality testing).

Agitation systems create and maintain hostile and corrosive testing environments;
performing high temperature Sour Service Testing (H2S) Sour Gas for Materials Testing.
