For pumps in high throughput applications, where abrasive wear and corrosion is a concern, 300 Below’s cryogenic processing technology provides 200-300% longer life for around 20% cost of the pump parts concerned. While many pumps are made from CD4MCU metallurgy, which will not respond to our process, other pumps made from white iron (high alloy 24%+ chromium) will respond most favorably to the 300 Below process, yielding reduced maintenance, less change outs, and less frequent re-machining of parts.

For pumps, any areas within the metallurgical composition that set with differentials in casting thickness will have stress concentrations due to the casting process, resulting in differential cooling rates when using the pump due to varying thicknesses throughout the pump metal.  When a pump is uniformly cast, you will have uniform cooling, and thus more uniform stress. When there is a variance in geometric shape, which there always is in a pump, it leads to stress concentrations or stress differentials which will impact the amount of wear in that zone. Edges, corners, and radiuses will typically fail in pumps. Thermal cycling could be impacted, but typically this is from two and three particle abrasive wear. The centrifugal boundary areas are the greatest impacted zones. Straight pipes typically wear better than bent pipes; centrifugal force causes accelerated wear.
