It should pump either the same. Ive had people tell me that their pump worked with water, but not paint....upon inspection, it didnt work properly with water either.

Being a big fan of Graco for decades and owning and operating the following rigs President 28;1 Monark 23;1 GH433 EH333 GM5000 and Ultra 750 I know about loyalty to team Blue.

Nothing... beats a good old fashion function test of the Equipment.
Run it in everything the current owner will allow you. I always brought the biggest tip allowed for the sprayer to make sure it would support what it was supposed to.

But to be honest with you I do not own any Graco rigs now. Speeflo and Airlessco are my sprayers of choice.

Pumps are designed to handle different products depending on what size they are. You asked what to do to test the pump to see if it works. Water will let you know if you have any seal leaks, if the packing is crappy, if the switch valve leaks. If the rig is spec'ed to handle more, it most likely will. Dont overthink this. I could shoot elasto through a small rig for a limited time, but I wouldnt recommend it. You wanted to know good advice for purchasing a rig from someone else, used, with no warranty.

Keep it simple.

We just pumped 30 gallons of decra-flex through a graco 490 ultramax II using a 517 tip and had no issues at all

Well we have been doing it for 3 years with this machine with no issues at all. So roll your eyes all u want. Just because the graco rep wants u to buy the $4000 pump doesnt make it fact. We have put at least 750 gallons of decraflex (100% elastomeric) through this 490 and will mosy likely put another 1000 through it in the next 3 years. Not bad for a $1100 machine

ICI Dulux and Glidden make a few of the Decra-flex Brands. I assume the product your using is ICI's. I just dont see you pushing Decra-flex glidden 200-300 series but I do see you pushing ICI dulux 1130 series can you tell me which product you are using? thank you robladd

Rob,

You are correct. The one i am spraying right now is the 1180 deep base. I wasnt aware of a 200-300 series and the differences between them.

My question is if you are doing this so often why not buy a 795 or 1095 and know that is was made for what you are using it for?

If it works it works I guess but as Rob said it is a thinner elasto. Myself rather than burning up a 495 prematurely I would rather buy a bigger pump and know that I could get a decade of elasto out of it.

We just shot 900 gallons of conflex through a 5900 gmax with a 527 tip. About a 5 every 6 minutes.

This too has no bearing on this thread.


BTW, a .x17 tip sounds kinda pointless for hitting any type of mill build spec for an elasto product. I think minimum tip size on a TDS is .x21.

Its the % of solids that will make the impact on wearing out the pumps, the higher the % the bigger pump you need.

Even if you removed the filters from that unit it would still fry. You answered your own question really. You cant afford the proper spray unit, you cant afford to be wasting money. Just save what you got and put money aside from jobs until you can afford a Graco 5900.

Actually...... Graco Price Buster

Just have it serviced or reconditioned. Still come out cheaper.

Did a lot of elasto specified coatings with 10 year warranty. The material
I used was Sonneborn BASF. First coat acrylic conditioner, second coat 22mils wet sprayed and back rolled using a 027, third coat sprayed with a 029 to 22 mils wet, that was the specified wet thickness when applying.

DFT was between 22-32 depending on surface purosity. I do believe you could spray ICI Dulux decra flex with a slighty worn 017 but you can only do a maintenance coat. It would take too long to get any real specified build with that tip. To do elasto work with confidence I have always used at least a 2 gpm pump but if I were to go as small as I could it would have at least a .75 gpm but I wouldn't use anythink bigger than a 019 and thats the smallest ICI recommends for decra flex.

So big boy what type of material are you using and what type of work?
Those are the questions you need to ask yourself before chooding your next rig. Sincerely Rob
