What the Hell!!!!!!!!!!!

May 2, 2010

First off, make sure your using a tip with at least a 40 size orifice or larger. Second, underneath the pressure switch there is a small Allen screw. You will probably need to adjust the pressure switch. Try to set it to where the pump is not cycling on and off. (with your spray tip on the gun).

You may also want to remove the gun and tip and run it wide open to see if you are still blowing fuses. If you are, then you have a wiring issue. if not, then do what I mentioned above. These pumps need a large orifice on the spray tips to keep the pump from pulling too many amps and either overheating and or frying.

Trust me, I feel your pain as I'm sure many others do as well. Been there done that. This is why I got sick and tired of baby sitting all my 12volt pumps and went to air.

I had the exact same problem with my 5800. Bought it from Bob too. Maybe it is something with the "pre wiring" that he does. I have no idea.

I am returning it for the 2nd and last time tomorrow.

Just like alot of guys here, I have switched to air and finished the setup yesterday. Had 2 jobs set up for today, but it is raining like heck here in Pittsburgh. So not sure how it will perform. I tested it yesterday and it ran real nice.

Just return the thing. There is something wrong with it, it is not YOU!

Upsize the suction hose supplying the pump with chemical. Use at least 3/4" id or 1" hose with crimped on fittings instead of using hose clamps. Hose clamps loosen over time and may allow air to get into the system.

Like Larry said, remove any nozzle. According to Mike Sullivan, the 12 volts pumps work better without a wand and poly gun assembly. Switch to just a ball valve and reducing bushing composed of pvc. You can get these at home Depot. Don't use 90 deg fitttings. Don't use a stainless filter in the tank. It will corrode and damge the diaphragms.

I sent a pm to you .

Thank you,

Lori

Exactly Lori. 1/2" hose, 1/2" poly guns, and nozzles smaller than #40 will cause premature failure.

For the 5850 pump use 5/8" output hose, 3/4"-1" intake hose, 3/4" ball valve, and #40 nozzle. Use 10-14 gauge wire.

My 5850's last up to 2 years with no problems.

The black poly head will crack and leak after about 2 years.

Replacing just the upper housing (head) only costs around $30 I believe. It's been a while since I ordered one.

Hi Larry, I'm Tom and this is my first post.

I've been around air compressor systems all my life and I'd rather get into an air-based system than one of the 12 volts.

Can you point me in the right direction to get started with a good air-based setup?

Thanks,

Tom

Tom, look 2 posts up from yor last one. Call Lori. I got my air pump system from her.

I had the same exact issues with the pump in a box I bought from bob. When I called him, he said no one is having the problems I was having, even though there were dozens of posts here and at his own ptstate forum of people having fat boy problems - pressure switch issues, blowing fuses, relays blowing etc.... And he had the balls to say *I* am the only one having these problems, so it must be the way I have hooked it up. I was using 1" PVC flex input, and it would not prime. Went to 3/4" line, and it still would not work. When I finally got it to prime, it worked for a few minutes,and then fuse blew, and the relay switch fused, and I could not turn it off...... I returned it to bob - for a full refund - which I give him credit for standing behind what he sells.... But he was a bit arrogant while dealing with him. Incidentaly, I bought the Northern Tool Northstar 5.5gpm, 60 psi ag pump.... Looks just like the delavan, but without a relay, and all the problems for $119. Has been working *perfectly* since I installed it as a transfer pump, and have done a few house washes with it "stealth mode" with no noisy compressor!

I'm going to have to go buy me a delavan pump so that I can have problems and start posting worth while questions on this board.

Roof Cleaning New Jersey · Jun 19, 2011

Each has its pros and cons. With the accumulator on the 12v I can now dial it down (to an extent) without cycling. My 12v now shoots farther than my air pump ever could. Ive had more problems with my air pump than I did with my 12v. Im more happier to have the extra space. I cannot take vehicles over7000 lbs on the Parkway, so I need smaller vehicles, no trailers. Clyde you would starve up here trying to navigate w/out the GSParkway. And Clyde please, please do something, anything to start posting worthwhile questions on this board. Im rooting for you.

I had my Delavan 5850 pump for about 3 weeks now and tested it last Friday, for the first time with a few issues with blowing fuses.

So I double checked the Marine battery and it had a full charge.

I pulled it out and finally hook the 175 ft hose to the hose reel and hooked up the pump to it and It ran for about 2 mins then POP. DAMN FUSE BLOWED. Replaced 3 more fuse and they all poped too.

What the hell is going on with this pump?

I will call BOB on Monday. Man this is not a good start for the Delavan.....

I don't run a fuse on mine.

Here is something that some of you may find odd but I have actually paid attention to. First I will ask you all a question... When you are sitting at home and all of a sudden you here a bunch of noise outside, what is the first thing you do??? Thats right, you go look to see whats going on.

I have found that we actually have picked up more neighbors from them being nosey and wanting to see what Mrs, Smith is having done to her property. Whether we are cleaning a roof, concrete or just a simple house wash osomeone ALWAYS hears us and is watching. I'm not saying that we pick up someone new in every neighborhood because of this but our ratio's per neighborhood have gone up considerably since we switched to cleaning roofs with air. when I used a 12 volt I still got their attention but it was from me yelling everytime my pump gave me trouble. (BTW, Not a good way to attract a potential customer). LOL.

confuse I know that using a fuse makes sense and I have used fuses on a few pumps for a while, but that connection is the one that fails first. So, I seldom use fuses and have no problems due to the lack of a fuse. -SO FAR!

Liberty SoftWash · Jun 19, 2011

I run air and use a 5850 for chemical transfer. The 5850 is not fused and I never had a problem with stall or a fuse. The last couple of jobs I have been using the 5850 for watering the plants.

I know you were just being sarcastic to make a point but there is a purely financial justification for the 12v pump system. A person that cleans less than 50 roof's a season cannot cost justify a $2k setup. You could buy 14 delavan 5800's for the same money. His money is better spent advertising.

For me, It was all about cost and ROI. If you pay $120 for a pump (5800) and get 120 roof cleanings from it then your cost is $1 per roof....60 would be $2 per roof. Considering the labor to swap one out (5 min?) and the $1 to $4 cost.....I always just considered it a consumable like trigger guns, fittings, etc. If you don't do a lot of roof's this is the best approach IMHO. If you are hitting 10+ a week it can become a nuisance with motor/battery/fuse/switch/etc problems.

With that said....and to completely contridict my previous point, I'm done with delavan setups. We bought 2 Fatboys last winter for this season and had to swap out on the third job. The 2nd job when it started going out (pressure switch) caught us without the backup on that truck and it took 3 times as long to finish costing me two roof cleans that day. We had maybe 45 min's of pump time when the first new Fatboy gave up the ghost.

I've only had 2 pressure switch problems in the 4-5 years of using delavan and if my volume of work was lower....I might stick with the $2-$4 per roof pump replacement cost concept...I'm just at a point where I want to invest in dual draw mixing setups. If I can draw water from the flow tank and draw sauce from another, I can decrease labor at the jobsite. I'd have done it sooner but I fought the idea of adding another gasoline engine driven component to the rigs.

We've also reached a point with a couple of vendors where I'm just not happy with the customer service. A new start on system and supplier.

I'm not trying to be sarcastic at all, I am just trying to fit in, I figure if I go get a delavan I will have something in common with the most of you, PROBLEMS .

Having used Delavans for quite a few years, if you follow the advice from Lori and others, they last quite well! I am using 2 right now, that have both been working for about a year. Use 3/4" intake spiral hose- a 3/4" pvc ball valve and the largest orifice tip you can properly control-for longest pump life. I use 200' of 1/2" ID hose-but if you don't mind hauling it around roofs, 5/8" and 3/4" are even better on the pump.

After you have it all set up, with hose streached out completely, if you have pump cycling trouble, start tightening the pressure set screw a bit, until it runs smoothly.

I know I will always use 12 volt systems for the simplicity and cost.

rinsing them promptly also extends the life.
