Stirrer Heads
Impellers for Overhead Stirrers
Powerful Stirring
Shaft diameter: 8mm
Blade and Half-Moon Impeller
- These impellers are recommended for applications which require an average speed
- For mixing products with average viscosity
- Models BR 12, BR 14 and HR 18 come with collapsible blade for narrow neck vessels
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....
Crescent-shaped stirring rotors, 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....

Compressed air powered stirrers, PLR, accessories
Connection couplings VK:
Fixed-diameter connection for motor/magnetic coupling drive shaft and stirring rod. Suitable for use in potentially explosive atmospheres. Material No. 1.4404.
Flexible glass stirring shaft couplings PK:
For stirring tasks using glass stirring rods. Elastic connector between motor and stirring shaft. Provides exact alignment of motor and shaft, and evens out axial and height differences. Accepts 6mm to 10mm diameter shafts....
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....
Additional Stirrer Blades for Bola Stirrer Shafts, PTFE
Useful extension to the existing range of Bola stirrer shafts. The additional blades can optionally be fixed in your preferred position on every stirrer shaft with diameter 8,10 or 16 mm (a flat spanner is included). The stirrer blades are entirely made of PTFE, the mounting devices are made of a special PTFE-compound. A high chemical and thermical (-200 to +250 °C) resistance is assured. This "building block system" allows the user to define a stirrer of their own special requirements....
