Stirrer Heads

Stainless steel. Supplied as separate 8mm diameter shaft with tapped screwthread end onto which can be attached a choice of paddle types. Lengths as indicated.

The paddle stirring rotor creates a tangential flow with minimum turbulence. Its design ensures a gentle action on sensitive products and good heat exchange. Recommended for low to medium speed operations.
Other sizes available on request.

For use with 9.950 401 and 9.950 402 shafts.

Stainless steel 1.4301. With screwthread shaft connection as outlined below.

PLR compressed air laboratory stirrers are designed for all kinds of standard mixing tasks. The vane type, air-driven motor offers a high power density and is significantly lighter and smaller than an equivalent electric motor.

General specifications:

• operating pressure max. 6 bar
• air consumption 260 L/min. at 6 bar
• power output 200W at 6 bar
• clockwise rotation
• ATEX certification

• all-stainless steel housing
• continuously adjustable speed control valve
• support arm diam. 14 mm
• snap connection for NW 5
• output shaft L x diam. 26 x 10 mm

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°C

Additional 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.

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.

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.
