air bubbles in pump discharge
air bubbles in pump discharge
It's just a normal flange connection centrifugal pump from Flowserve. The work I'm doing requires me to run the feed tank very low, and with the low NPSH I vortex at times. Finally figured out a great new vortex breaker.
And with tightening the bolts on the pump casing, there's no more air in the system. Uber happy.
What i've noticed, since I work with tri-clamp, is on some of the discharge piping, if I have a high enough velocity, it works kinda like a venturi or jet pump. It will suck air there instead of leak. So many strange things.

1gibson, I tightened the bolts on the housing. 8 bolts. eahc turned about 1/8th of a turn. And the bubbles went away.
I guess i don't understand why it didn't leak under high pressure. But it's fine now.
I spent all morning trying different combinations with the pump and the system to see if i could isolate where the air was coming from, finally decided it was the pump and tightened the bolts.. viola.Pneumatic and electric diaphragm pumps
