HR 18 Half-Moon Impeller
P/N: 509-18000-10
Blade and Half-Moon Impeller
- These impellers are recommended for applications which require average speed
- For mixing tasks with little or average viscosity
- With collapsible blade for narrow neck vessels
Selection parameters
Precise working with an overhead stirrer depends on the right choice of the stirrer tool. When choosing a stirrer tool you have to consider its different characteristics and their effects. For example, the flow which the tool causes in the medium, the tool´s adequate field of application depending on the speed range, and the execution of the tool according to the viscosity it is destined for
Application examples:
- Gassing of liquids < 500 mPa s: Radial Flow Impeller
- Homogenizing and suspending in liquids < 500 mPa s: Propeller-Type or Blade Impeller
- Medium with a viscosity > 500 mPa s: Anchor-Type Impeller, Blade Impeller BR 13, VISCO JET®
- Stirring of gel: VISCO JET®
Please ensure that for radial flow, blade, half-moon and VISCO JET® impellers the beaker size and position of your impeller complies with the shown guideline to achieve superior mixing results
Operational guidelines
Position of the stirring tool
- In center
- Distance to the bottom (h3/d2): 0.3
- Diameter vessel (h1/d1)=1
- VISCO JET® diameter ratio (d2/d1): 0.4 - 0.6
Circumferential speed
- 3 - 15 m/sec: Radial Flow Impeller
- 2 - 5 m/sec: VISCO JET®, Blade and Anchor-Type Impeller
