Low-friction coating to improve pumping efficiency?
(OP)
Dear colleagues
We are looking for Low-friction coating to improve pumping efficiency.
Are there other products beside Belzona & Corrocoat products for that kind of Low-friction coating?

But I go with the last post. Unless you are dealing with hundreds of HP and are running exactly at BEP this will be more effort than it is worth.
I have flow polished pump stages with a slurry extrusion process. That did help, but we were actually slightly changing the stage geometry

As with flow in pipes it is Reynolds number dependant.
The paper below gives you some theoretical and empirical background that you can use to evaluate potential for your specific design.

We used to coat eight foot diameter Thames water pumps with one of the Devcon rubber type products, both as a friction reducer and to improve wear resistance. Worked very well from a wear resistance point of view but not sure about the improvement in performance.
