Re-build Spray Rig

[LBrown59]

First thanks for the link.

*I was told the pump would have a hard time drawing fluid from the to and and to try and draw from the bottom.


I guess it would self prime. Have you done this from the top only?

*Works fine for this fuel station.

How would you get the tube through the top of the tank?

I plan to use the 3/4" threaded piece in the fourth picture that is on the top of the barrel as a return line/port. There is a small hole there now which will be enlarged and a 3/4" fitting attached. I'll also fill it from the top from the other hole( there are two). My understanding is the pump would not be able to draw effectively from the top(siphoning) so that's why I wanted to put the fitting on the bottom. This will be my return/agitation line from the relief valve. An issue now is getting the 1.25" inch fitting in the bottom reduced to the proper hose size to feed the rotary pump.

Yes, I looked at that set-up - it's nice. That thread didn't list the different pieces of equipment, but I'd be interested how you set that up and where you got the pieces.

What partws do you mean ?

The pumps etc. Since I posted that I found a guy that can spin in threaded pieces wherever. which I wanted in the bottom of my barrels. I'm hoping to get my sprayer together this weekend and paint early next week.

I'll try and post some pics.

Okay, mostly assembled now with new paint, nozzles(teejet 8003s), 20' width, wet booms. will probably add some ports to the manifold system for a hand held gun and maybe a spray attachment to nuke over grown fence rows.

Here are some pics.

Still have some questions, should I connect both tanks simultaneously or put in an either/or valve? Also, I am thinking I should put an inline strainer in upstream from the pump to keep gunk from the tanks out of the system.

Yes you need a strainer between the tanks and pump.

I may have mentioned it but I install quick disconnects on my pumps and my sprayer ends. This allows for switching any pump to any sprayer or one pump between more than one sprayer. It also allows for quick draining of a system or pump. It keeps them from sitting there holding water or spray mix to prevent rust and freeze damage. I also pull my pumps off and drop them into a 5 gallon bucket of old oil. Since doing that for about 2 or 3 seasons no more pump rebuilds.

Where do you get the quick disconnects? I've been looking at that. I still have the issue of one or both tanks.

I still have the issue of one or both tanks.

I'd valve both tanks into a "T" so you can pull from either or both. Are you going to have recirculation feed in to both to keep the chemical mixed?

I guess I could on both counts - the feed into the pump and then out of the relief valve back into the tanks(not upstream on the in side of the pump). I've seen the three way valves that let you feed option 'A' or 'B' but not 'A' and 'B'.

While I'm thinking about it. I am having a hard time getting the hoses on the barbs what to folks use to make that a little easier?
