Hai all
I am working on a slop oil system containing slop oil tank and pumps. The slop oil pump is submersible centrifugal pump.
- Does a submersible pump require minimum recirculation line?
- If required, as a general practice, what should the failure position of the control valves located in pump main discharge line and minimum recirculation line be?
- What are the governing factors in determining the failure position of these control valves?
Please do inform if any further information is required.
Thanks in advance
