The 3-bladed stainless square pitch impeller is the staple impeller for many mixing processes due to its efficiency and durability. Mixer Direct’s right-handed propellers are solid 316L for maximum corrosion resistance in most environments. As right-handed rotation propellers, they will pump in an upward direction when rotating clockwise looking down the mixing shaft. This can be ideal for some products with high settling rates or sensitivity to air impartation.
