How to Determine a Left Hand vs. Right Hand Propeller

In this video INDCO illustrates how to determine a left hand versus a right hand propeller. The video features a 3-bladed marine style propeller. We use three methods to determine left hand vs. right hand; blade angle on hub, palm demonstration and flow of material. These methods will work on our steep pitch, square pitch, buffed and mirrored propellers. To view flow of material we use an AS Air Stirrer with a left hand and right hand propeller in water….

Dispersion blades offer shear of particles in a high speed application.  INDCO has discussed dispersion in earlier blogs: Fundamentals of Dispersion: A quick reference guide and Dispersion Blade Designs: A Brief Discussion.  INDCO has 5 different designs available depending on your application.  There are a variety of methods to mount the dispersion blade to your dispersion equipment. Two shaft options are available for use with drills or stirrers.  The TS series stainless steel shafts are available in lengths from 12”… Read More

Mixing Propeller Design: Measuring the Marine Style Mixing Propeller

The marine style mixing propeller features three equally-spaced blades. Therefore, direct measurement of the propeller’s diameter from one side straightthrough the center to the other is not possible.  A useful method is to measure the radius from the center of the bore to the tip of one of the blades then to double that measurement to determine the impeller’s diameter. Blade pitch is another characteristic of mixing propellers.  Direct measurement of actual blade pitch is quite complex and is usually… Read More
