Propeller stirrers for overhead stirrer EUROSTAR 20 high speed digital / control

Propeller stirrers, 4-blade, stainless steel 1.4571

The 4-blade propeller stirrers provide axial flow and create increasing shear forces at higher stirring speeds. Recommended for medium to high speed operations.

Propeller stirring rotors, 3-blade, stainless steel 1.4305

The 3-blade propellers produce axial flow, and reduce shear forces to a minimum, even at high stirring speeds, thanks to their optimised blade design. Recommended for medium to high speed operations.Other sizes available on request.

Propeller, 3 blades, PTFE

The stirrer shafts consist of a PTFE-jacketed, stainless steel shaft and a stirrer paddle made of solid PTFE. The stainless steel core assures stability of the stirrer shaft and allows safe attachment of the stirrer chuck. Thanks to the thick PTFE coat and the paddle made of solid PTFE, the medium will only come into contact with PTFE. High chemical resistance makes it almost universally suitable. PTFE is extremely nonstick so that residues are repelled from shaft and paddle. The stirrer shafts are similar in size to (KPG) glass stirring rods and are therefore interchangeable easily.Operating temperature: -200°C to +250°CAdditional sizes and accessories are available on request.Information on the mixing effects of the different stirring geometries can be found in the descriptions of the stainless steel stirring rotors.The blades are inclined at 45 °. Recommended for medium to high speed operations.

Rods for stirrer rotor shafts, M6, M8 and M10 screwthread end

Stainless steel 1.4301. With screwthread fitting as outlined below.

Rotor shields

Safety limit switch SI 400

The SI400 consists of an end switch (normally closed contact / switch) and a magnetic switch contact (actuator) which is mounted either on the floor stand R472 with the fixing device SI472 or alternatively on the telescopic stand R474 with the fixing device SI474.The stirring unit RW47 can only be switched on through the SI400, when the agitator is adjusted to the user-selected height within the mixing vessel.The power supply to the RW47 automatically shuts off if the stirring unit is lifted above the selected height.

Speed regulation valve V

Fine control valve for stepless speed regulation.

Spiral stirrer, stainless steel 1.4571

Generates axial flow. Medium is conveyed from the bottom upwards. For homogeneous mixing and heat exchange of medium to high viscosity media. Recommended for medium speed operations.

Turbine stirrer for Overhead Stirrers

These impellers are recommended for applications which require an average speedFor mixing products with average viscosity up to <500mPasIdeal for gassing of liquidsThese impellers create a radial flow

Turbine stirring rotors, 3-blade with guide ring, stainless steel 1.4305

The 3-blade turbine stirring rotor produces axial flow; the guide ring surrounding the blades reduces shear forces, and offers protection when contacting the wall or bottom of the vessel. Recommended for medium to high speed operations.
