Magnetic Agitators & Stirrers


Magnetic Agitators & Stirrers are often used in simple thin walled laboratory Vessels and Reactors by chemists all over the world.  KW Designed Solutions has designed and developed an advanced range of high-pressure Agitation & Mixing Systems utilising a leak-free magnetic coupling that negates the use of rotary seals.

Our compact designs incorporate an Inner Magnetic Stirrer Assembly that is housed 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 that we guarantee the right level of agitation or mixing for fluids with various viscosity levels. 

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

With all internal wetted materials manufactured from exotic stainless steels, our Magnetic Agitation & Mixing Systems are ideal for use in test environments using aggressive chemicals at high temperatures, for example, the agitation of high temperature, high-pressure sour gas H2S in HPHT testing applications.

Magnetic Agitators & Stirrers


Features

  • Top, bottom or side mounting
  • Designed for easy maintenance
  • Operating pressures up to 1034 bar at 350°C
  • Speeds up to 4000 rpm
  • Designed for corrosive environment (Turbid seawater sand and silt, H2S Sour Gas, Methane, Acids)
  • Hermetically sealed Pressure Housing
  • In-line or Belt driven motors depending on space availability
  • Various impeller designs

Benefits

  • Replacing typical rotating shaft and mechanical seal configurations with our Hermetically Sealed design ensures zero leakage of pressure and test media
  • Variable speed and torque allows for use with aggressive media with varying viscosity
  • Provides efficient stirring and mixing
  • Compact, integrated design ensures space saving

Applications and Customer Uses

Magnetic Agitator Drives used within Agitation systems have proved to be a very popular choice for our customers who work within the Subsea, Oil &Gas and Materials Research industry sectors.  

For our customers dealing with stringent Subsea testing demands, these drives are used in Agitation systems for creating turbid sand and silt seawater environments, whilst conducting wet-mate electrical connector testing (Mate/Demate functionality test).

For those involved in Materials Research, performing high temperature Sour Service Testing (H2S Sour Gas), these drives help Agitation systems create and maintain hostile and corrosive testing environments.
