Drain a pump body for maintenace
Drain a pump body for maintenace
(OP)
We have open system like cooling tower loop for chillers including two cooling water pumps. If we have to isolate pump for maintenance,is there any requirement of vent a pump body before opening drain nut of a pump body or can we just open a drain nut?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

You can easily get vent plugs which are needle type plugs which don't extend all the way. Just fit one of those if you don't want to fit a valve.
You can also get them as part of the plug - see typical here http://www.technicalspecialties.net/store/Accessor... or this
