Marine Propellers

Speed range – 400 to 1800 rpm

Top Entering – Diameter < 450 mm

Side Entering – Diameter 250 mm to 850 mm

In a theoretical environment, one full revolution would move the liquid longitudinally a fixed distance depending upon the of inclination of propeller blades. The ratio of this distance to the diameter of the propeller is known as the pitch of the propeller.  Propellers are available with 1.0 pitch ratio; these are often referred to as square pitch.

Variations include four bladed propellers, propellers with saw tooth edges for tearing action, perforated blades for shredding and breaking of lumps.

Marine propellers are also used on side entering mixers. They are mounted with the impeller shaft inclined at an angle with respect to the vessel centerline, for improving process results.
