FABRICATED MIXING IMPELLERS FOR BIOPHARMA AND SANITARY AGITATION CALL US FOR ANY CUSTOM MIXING IMPELLER, WE WILL BUILD ANYTHING

WMProcess offers a wide range of sanitary mixing impellers which are fabricated (not cast) and include material test reports for typical biopharma use.

Marine Style Sanitary Impeller – BioProp Mixing Impeller
Axial flow mixing/blending

We offer various angles on the WMP Bio Impeller blades, and typically would be a 3 blade impeller: Power Number (Np) = 0.50-2.0+    
Flow Number (Nq) = 0.45-1.0+

The BioProp is a great impeller for agitators and mixers  used in the sanitary and biotech markets. This blending prop provides excellent pumping ability and is self draining and very easy to clean.   Typically built in 316Lss, it provides similar performance to a marine style propeller, but it is fabricated and not cast.

This BioPropeller mixing blade can accommodate just about any shaft diameter.   It comes can be fabricated in numerous alloys and sizes from lab to production.

Mixing impellers for biotech applications often are 316Lss, welded to the shaft, polished to <20RA, and then passivated and electropolished.  Impeller should also be self draining and capable of being cleaned via CIP and SIP.  

Contact White Mountain Process for any questions on CIP cleaning of agitators or reactors.
