Pump inlet/outlet full port bypass

[2bad4um8]

What are the consequences of having a full port bypass going from a pumps outlet to it's inlet? Cavitation? Upstream flow?

Bypass has a valve that is partially cracked.

Process material is high visc and usually heated.

Recycle from discharge to suction, less flow, less cavitation, less discharge pressure, higher temperature discharge (probably negligible).

Good Luck,

Usually these lines go back a ways so that the recirculated product can be mixed in better.
This help even our temperatures and minimize shear related issues.
