CD4MCu is a duplex stainless steel, with greater corrosive resistance than standard stainless steel. CD4MCu provides significantly better chloride stress cracking resistance than standard stainless steel, and much better localized corrosion resistance.

CD4MCu allows the pumps to be used in more abrasive applications, and it won’t pit like regular stainless steel, has a better stress/corrosive cracking resistance than standard stainless, and higher strength than standard stainless steel. And compared with regular cast iron material, it is much more resistant to corrosion and much stronger.

The difference in bores ( flow modifiers) can be explained as follows:

Standard Bore:  was designed for packing and also can be used with mechanical seals.  It is ideally used with Water based liquids with flush.

Big Bore:  the big bore chamber was designed to achieve improved lubrication and cooling of the seal.  It is ideally used for the following:  Water based liquids with flush,  Solids greater than 10% with flush, Paper stock with 0 to 5 % with flush, for seal face heat removal.
