Pumpout Questions

Let's say I have a 5 gallon bucket vaccuum with a 120 v head. What 120 v pump could I use to convert that into a pumpout vac that would have enough juice to overcome the vaccuum effect AND pull out up to 8gpm AND run dry if needed?

Any ideas?
 
A good submersible pump would suit your needs...but a 5 gallon pail? Kinda small, ain't it?
 
The Lowes vacuum is what we've used for the past couple of years. They are cheap and you can throw them away when they poop out on you. Amazingly we have one that has lasted over a year now and still going strong. The only problem with this unit is it vacuums faster than the pump can pumpout and if you get a little ahead of it the vacuum shuts off.

Russ, This is for vacuuming runoff when cleaning evaporator coils. We only blast in spurts and I was looking for a less bulky alternative to the Lowes unit. Is there anything I need to look for in submersibles? I don't know anything about them.
 
Russ, I've got another question.

Say I have a 6gpm 1500 psi unit and a 4 gpm 3000 psi unit. Both have pressure unloaders.
1st - can I just hook them together with a "T" and get 10gpm? or do I need check valves?
2nd - What will my pressure be? 1500 psi or 2250?
 
If you do put a pump inside of that vacuum, make sure it is suspended.

Cheap skate...;)

A decent gpm rating, which will be reduced due to the pull of the vac, and a check valve on the outlet.

You can just hook up with a T, but I recommend check valves, too. You'll end up with the lower pressure of the two, 1500.

It can pump 23 GPM and is self priming so if it pumps dry it will still pick up when you start filling it again . It only draws 2.5 amps and you can wire it with the vac and it won't pop a breaker. It says clean water use but mine has worked over a year pulling water,chem and grease chunks out of a vac with no issues.
 
Alexy, how many cfm and water or Hg lift is your vacuum?

I am wondering because this might work in a larger system like my electric system, if so that would be great. My electric system is 230cfm and 110" of water lift (10" of Hg lift). It would be nice if that would work in that system, I would then only need 2 outlets to plug it into instead of 3 for the 3 separate electric cords (2 vacuum motors and the sump pump).

Thanks.

Its a Mi-t-m 1300
Specs here:

115 CFM can hold 9 gallons of liquid water lift is 93 inches (9.3Hg) The pump has no issues with keeping up with the vac and you loose almost a gallon of capacity with the pump but since it is keeping it almost empty it doesn't matter.
 
Thanks Alexy.
 
Lowes Shop Vacs aren't built very good. I dropped one last weekend off a boomlift 30' up and didn't survive.

I went and got a Rigid from Home Depot and it's a lot better vac than the Lowes brand.
