Circulating orientation + air leak during pressure test questions

Fluke216

Are these pumps orientated correctly? It’s hard to tell exactly from the diagram in the paperwork.  Also the gaskets on either side of one of the pumps was  leaking air around 50 psi tightened them some more then around 60 they were leaking again anyone have experience with these I think I over tightened now as they were continuing to leak air. The systems only going to be at 12 psi and maybe water will be fine I could isolate them and test rest of piping anyway any advice is appreciated thanks.

The leaking gasket problem may be from misalignment of the pipes. Gaskets are meant to seal, and usually won't tolerate any significant angular misalignment.

you need to use the Grundfos gaskets with those iso  valves, any other type or combination will often leak

30 psi test should be plenty?

The flow is going left to right. Not sure if the pumps should be mounted upside down check the install sheet.

Motors should not be installed facing the floor or the ceiling. The motor shaft must be installed horizontally.

You should use the rubber ring gaskets that come with the circulator. they never leak. And will last far longer

spin circulators 90 degrees for proper orientation.

The ring gaskets will not work with those flanges. Needs to be flat gaskets with no larger than  a 1” hole or gaskets miss the sealing surface on the valve. The gaskets that come with those valves fit perfectly

Sorry guys thanks , turns out I’m an idiot I few minutes after I posted this it clicked. I installed both gaskets I took the rings out and it worked perfectly I think I have the correct pump orientation now I spun the pumps up so the junction box is facing up.
