Description
BOLA Maxi propeller stirrer shaft, length 800 mm with shaft diameter 16 mm, is a PTFE-coated stainless-steel stirring element for laboratory and process mixing. The shaft is PTFE-coated stainless steel, while the propeller is made entirely of PTFE and carries three blades inclined at 45°. Outer propeller diameter is 140 mm, with blade dimensions 140 mm × 26 mm × 6 mm according to the manufacturer drawing; chuck diameter is 14 mm for secure clamping in standard drives. Because the medium contacts only PTFE, the assembly provides universal chemical resistance to aggressive reagents and solvents. Net weight is 1,165 kg and the item is supplied as 1 pc. This Maxi propeller design from manufacturer Bohlender combines mechanical strength of the coated steel core with the inert wetted surface of PTFE, making it suitable for axial-flow stirring in larger vessels where corrosion protection, cleanability and reliable blade geometry are required. Dimensions and materials match the stated BOLA Maxi specification for consistent performance in chemical and pharmaceutical environments.
This article is part of Stirring shafts, propellers & impellers, in Stirring, shaking & mixing.

Questions about BOLA Maxi Propeller Stirrer Shafts, L 800mm, Ø 16mm, aØ 140mm PTFE-coated Stainl
What is this article?
BOLA Maxi Propeller Stirrer Shafts, L 800mm, Ø 16mm, aØ 140mm PTFE-coated Stainl is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Stirring shafts, propellers & impellers, inside Stirring, shaking & mixing, in Lab instruments.
A shaft, a propeller or an impeller is the wetted end of an overhead stirrer. The diameter and the pitch decide whether the liquid turns over. The material, stainless steel or PTFE, decides what the liquid may be. The chuck size has to match the stirrer.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
