Pump mounting

[paul692]

Can you mount a pump upside down or inverted under a stand ? Will it wear out the bearings or impeller prematurely

If you mount it upside down the water will flow backwards, just kidding. Seriously though, it should not be a problem. Everything should be fine.

So how is water going to get up to it? I'm assuming a sump is down in the stand and this is a return pump. Now if it's a closed loop circulation pump...no problem.

i wondered about that also so the pump wont suck water up that high out of the sump about 18 inches or so?

Probably not. They are made for water not air.

Nope! As far as I know, there is not a self-priming pump in our hobby. They all have to get water to them before they can pump it and the last thing you want is a pump to go dry. It'll burn up in no time.

I guess I will drill the sump down low and put a fitting in there will this work? Any other suggestions out there? I want to keep the return pump out of the sump to free up some space.

That's the standard practice. I would recommend that you look at pictures of sumps before you decide where to cut the hole. The "fitting" is called a bulkhead and is generally the same size as the inlet of your pump.

Yes... keep the input to the pump below the water line of the sump.

An external pump means another thing that can leak. I'd just get a bigger sump.

I will put a ball valve after the bulkhead with unions if the pump leaks I will cut off the ball valve and put the pump back in the sump I need a 1inch bulkhead same size as the pump. I have a hole saw at various sizes at work I think.should be a no brainer I hope.i will drill as close as I can to the bottom of the sump.not to concerned with a leak

Just finished drilling my sump no leaks just waiting on my new quiet one pump to arrive.
