External-gear-pump operation.

External-gear-pump operation.

(OP)
If in an existing installation for diesel pumping with subj. type pump the diesel is replaced with water, will there be a substantial difference in the discharge pressure ?

RE: External-gear-pump operation.

Not in the immediate sense, but very shortly thereafter as corrosion imparts permanent damage to the pump. Stainless steel components may have a bit more durability but the lack of lubricant will stake it's claim non the less.
