New shur flo a dud!!!

[JR Wood]

About a year ago I recall someone posting that their shurflo didn't seem to work right.It would just pulse and the spray pattern just wasn't good.At the time the shurflo I had worked perfectly,the pump would cycle fast and even so I thought that it was a problem with a clogged inlet or something.I just got a new one that seems to totally suck!!!It cycles unevenly and you can see the pulsing spray pattern when you apply cleaner or stripper.Is there any way to adjust the cycling.It is really bad when using stripper.You have to go over the deck twice to get good coverage.The system is clean and there are no clogs anywhere.Also does anyone know where to get a hose reel for my shurflo....I would like to use 150 or 200 feet so I suppose I will need a 100 psi.Right now I am using 1.4 gpm @60 psi with a fifty foot hose, and it works good as far as output goes.I am tired of lugging the cart up to the deck I want everything truck mounted so I can spend more time cleaning and less time setting up.

JR im not 100% sure but i think there is a adj screw on one end of the pump.
I think its just a small hole in the outter caseing and the screw is inside. You need a very small screwdriver.

JR, the pressure drop depends very much on the ID of your hose, as well as your flow rate. Here are some approximate pressure drop estimates for 100 feet of hose:

1. 1gpm, 3/8" = 7 psi
2. 2 gpm, 3/8" = 25 psi
3. 3 gpm, 3/8" = 50 psi
4. 1 gpm, 1/2" = 2 psi
5. 2 gpm, 1/2" = 6 psi
6. 3 gpm, 1/2" = 13 psi

For 150 hose, plus fittings you could multiply by 1 2/3 to get pressure drop. I am in process of designing/putting together a Shurflo system myself. I have concluded that if I use to get on roofs, etc., I will shoot for a 100 psi system, and get 1/2 inch hose so that at some point I can use a 3+ gpm pump. Believe you are doing just decks; because I am new to decks, I would personally go with a 1 or 1.5 gpm system, in which case a 50 - 60 psi pump with 3/8" hose would suffice.

My larger problem is finding a pump that can handle the multitude of chems I am currently and gonna use.

Regarding your pulsation problem, almost sounds like you have set down at the bottom of the range, causing it to cycle on/off.

Hose Reel

I have a shur-flo on my trailer that leads to a hi pressure reel. Just put on the barbed connectors for the hose and attach your 3/8" or 1/2" hose to the outlet on the pressure reel. Mine came this way third hand. It seems like overkill, but its a cinch to pull out 200' of hose and then reel it up when i'm done with the spraying.

Hope this helps.

THANKS Ron P!
A quick turn with an allen wrench on top of the pump solved the problem.

Mark D. Does your high pressure hose reel have chemical resisitant seals? I would like to spray stripper with the set up also.Also what kind of hose are you using?

JR i have a compressor on my rig and am thinking about useing 20 gal poly tanks with a air fitting installed. Then use a valve with a quick disconnect on the bottom of each one. Also the same for the air connection.
Then use a pressure reg. for the air and a hose and wand for the working end.
I need to know how much pressure would be needed for a 100 ft of hose and if the tank could take it.
If these tanks cant take the pressure im going to have to use the soda kegs.
I bring this up just to show there is more then one way to get the job done, that your looking to get done.
Another thing Do you think there are enuff guys here in NJ to set up a buying ring?
Everyone buys once a month from the same dealer and truck ship to one location.
We meet there and pick up our supplies. Shipping costs are the killer.
We could also talk over stuff to make us more money and no BS with the lowballers that are smart enuff to read the bbs. Buying in bulk would save a ton of $$$$.

I want one of those green tanks they have at home depot.It is a 35 gallon pressurized tank that they water the shrubs with.
