RE: Coating selection
Hi texnicar
To answer your question is necessary to know the working media the pump works, and for the high pressure of 150 bar, APS coating is not recommended, the only coating that surely works is a spray and fuse Ni base powder, I recommend Colmonoy 88, and as alternative coating HVOF chrome carbide powder
Best regards
Luigi
