Propeller-type 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.

• Due to its blade dimensions, the ringed pitched-blade impeller PR 33 is ideal for solutions, emulsions and suspensions in vessels with the following characteristics:
• Ideal vessel diameter: 165- 330 mm
• Ideal ground clearance: 33- 66 mm
• Ideal filling level: 165- 330 mm
• Ideal volume: 3,500- 28,200 ml
• The ringed pitched-blade impeller PR 33 has a total length of 400 mm and is made of stainless steel. Its stirrer shaft has a diameter of 8 mm.

• Due to its blade dimensions, the ringed pitched-blade impeller PR 32 is ideal for solutions, emulsions and suspensions in vessels with the following characteristics:
• Ideal vessel diameter: 113- 225 mm
• Ideal ground clearance: 23- 45 mm
• Ideal filling level: 113- 225 mm
• Ideal volume: 1,100- 8,900 ml
• The ringed pitched-blade impeller PR 32 has a total length of 400 mm and is made of stainless steel. Its stirrer shaft has a diameter of 8 mm.

• Due to its blade dimensions, the ringed pitched-blade impeller PR 31 is ideal for solutions, emulsions and suspensions in vessels with the following characteristics:
• Ideal vessel diameter: 83- 165 mm
• Ideal ground clearance: 17- 33 mm
• Ideal filling level: 83- 165 mm
• Ideal volume: 400- 3,500 ml
• The ringed pitched-blade impeller PR 31 has a total length of 400 mm and is made of stainless steel. Its stirring shaft has a diameter of 8 mm.

• Due to its blade dimensions, the pitched-blade impeller PR 30 is ideal for solutions, emulsions and suspensions in vessels with the following characteristics:
