Overhead Stirrer Impeller PR 39 Pitched-Blade Impeller
Due to its stirrer blade dimensions, the PR 39 pitched-blade impeller is ideal for homogenizing very viscous media in vessels with the following characteristics:
- Ideal vessel diameter: 188-375 mm
- Ideal ground clearance: 38-75 mm
- Ideal filling level: 188-375 mm
- Ideal volume: 5,200 - 41,400 ml
The pitched-blade impeller consists of a PTFE mixing blade and a PTFE-coated stainless steel shaft. The stainless-steel core ensures the stability of the stirrer shaft and the secure attachment in the overhead stirrer. The diameter in the clamping area is 6.5 mm; the stirrer shaft with the thick-walled PTFE coating has a diameter of 8 mm.
Due to its anti-adhesive property (non-stick coating), the pitched-blade impeller is easy to clean and can be used up to a maximum application temperature of 250°C.
