Rebuilding a sprayer...

pashworth · Mar 15, 2009

50 Gallon Mighty Mac tow behind sprayer, 3.0 B&S engine. Tank, frame, tires, wheels, axle are all in good shape. I have scoured the site and found the answers to almost all my questions and plumbing problems except two.....
What hose type should I use? Single braded vinyl?
I assume that the china made supplies in TSC are acceptable? I am mainly concerned about the diverter valves and filters, shut off valves......

Instead of rebuilding the carb, new filters, plug, magnatron, starter cord, handle, rewind coil and anything else that prevents it from starting / working properly, and also rebuilding the twin piston hypro pump..... I am going to get a new Hypro 6 roller pump and hook it up to the PTO.

Thoughts,
Paulie

Who says New Jersey is ugly? That's a nice area you live in. Do you know where Lake Hartung is?

Yeah Jersey ain't bad! I dont know where lake Hartung is, sorry. North or south?

What kind of hoses did you use? What is that black hose is what I am asking? Where did you buy your parts from?

I believe Lake Hartung is in the central to northern part of the state. My Mom's parents had a small summer house there. I do feel for you with the high property tax burden the "Garden State" has.

My sprayer is a highly modified FIMCO/Schaben unit; but the hoses came with the sprayer, and I believe they are braided EPDM rubber. The hose on the reel is PVC and came with the reel.

Gempler's www.gemplers.com sells some of the smaller diameter hoses, and FIMCO's parts department has been quite good when I needed parts. www.fimco.com

I'd also check McMaster-Carr www.mcmaster.com for hoses. Their catalog has just about anything and everything you will ever want. Every time I get an order delivered, I feel like a little kid on Christmas morning.

Matt,

Thanks for your help. I didn't mention it before, but your fabrication skills are excellent.... wanna come on over this weekend and fab the parts I need to make my boom and mounting arms? HA!

Sice I have a 10% coupon off on all TSC stuff I though about buying everything I need there, but am concerned with the quality. I was asking if previous builders / modifiers of sprayers had a preference on the parts manufacture.

On the hoses and fittings, since I am primarily spraying Round-Up, which is corrosive to most metals I am using plastic as much as possible... RIGHT?? Can I use the Ethyl vinyl acetate plastic tubing from TSC which "handles common herbicides and insecticide solutions" as per the website or do I have to use EPDM Agricultural Spray Hose they sell?

The price difference is about 20$ for 50 feet. Not that I dont want to do this project right, but still being unemployed, I need to save every dollar I can get.

Thanks for everyones help.

Hi Paul:

Thanks for the kind words on my metal working, I do appreciate it.

Not being a materials engineer, I don't know about TSC's ethyl-vinyl-acetate being acceptable or not for Roundup use. I am guessing that PVC should work as that plastic is pretty forgiving of most room temperature water based liquids. If I'm wrong with my guess, I hope someone chimes in with a good alternative. We don't have TSC in Colorado, so I have no idea what they sell in the stores.

My gripe with the EPDM sprayer hose is that its outer jacket cracks from the sun's UV light. Whether this affects the hose's performance is unknown to me; but I'm guessing it will be OK for a while since the manufacturer's use the stuff and the sprayer's sit outside at the dealers. If the hose reel's PVC hose works, I'll eventually switch to it as I need to replace hoses.

I got my sprayer from Gemplers since they had the best price at the time including shipping than I could have got from the dealer.

I run a pre and post emergent herbicide called Pro-Deuce through my rig, and I double rinse it after running a Nutra-Sol type of neutralizer through the tank. I also keep anti-freeze in the pump when done, and about 1/2 gallon in the tank and hoses. The anti-freeze helps to lubricate the pump parts and inhibit rust and corrosion.

I hear you on needing to save a buck; best wishes to you finding employment soon.

Sorry for rambling on.

Get rid of the galvinised metal pipe - that does not work long at all, esp with RU.

Typical to use the black rubbery-like sprayer hose. I think the cheaper stuff you mention would work fine with a less powerful electric pump (might want to use on of those???) but a 6-roller pump will put out 100psi and I promise, at some point you will end up doing that when things block up, and you really don't want to blow a hose when that happens.... With the roller pump, I'd go with the good hose - looks like radiator hose for your car heater....

If you go with a less-aggressive electric pump with lower max pressure, the cheaper hose might be good.

For the suction side, you really need suction hose - the harder ribbed stuff. Again, a good roller pump will flatten out most regular hose & collapse it. I don't think the cheap stuff will work for suction at all.

My concern would be bursting strength. Either should handle the fliud, but you are using a pretty good pump, need to match up the tube to handle it.
