Marine Type Propeller


Marine propeller is an axial flow impeller. Standard propellers have three blades, but can be two-bladed, four-bladed, or encased by a circular guard. A revolving propeller traces out a helix in the fluid. One full revolution moves the liquid a fixed distance. The ratio of this distance to the propeller diameter is known as the pitch. Marine type is often used as a side-entering mixer in large tanks and as a top-entering mixer in small tanks. It can be designed with a different pitch to change the combination of pumping rate and thrust.

Technical features:

They are used at relatively high speeds (up to 3000rpm) with low viscosity fluids, up to about 4000cP.


Used for blending, solids suspension, solids incorporation or draw down, gas inducement, and heat transfer.
