Cleaning a Sprayer PTO Pump

[trook]

I have a 100 gallon pto sprayer and primarily spray roundup which I am aware is very bad for pumps unless you habitually clean the pump after spraying. I realize that many individuals run clean water through the tank/pump and they place motor oil, vegetable oil, antifreeze, etc into the pump for storage.

With my particular sprayer, it is very difficult to remove the hoses from the barbs that are connected to the pto pump. I am wondering if any of you have rigged up some type of quick disconnect or something similar that allows you to easily place oil into the pto pump without having to go through the trouble of having to disconnect the hoses from the barbs.

Thanks in advance, and pics are appreciated!

The larger ring will unscrew and separate, I keep the cut off on the tank side. There is a big "O" ring to keep water tight even under pressure. I have one on both sides of my pump. I do put oil in my pump for winter and bring it inside.

If your pump is not stainless but cast, it's on borrowed time anyway. Roundup will eventually destroy it. I just run tank wash through my big sprayer and call it good but then I don't spray Roundup with it and yes my roller pump is stainless.

Trook,
I had the EXACT issue. I installed camlocks on my hoses, now it is a breeze to clean everything. The part look like this: (bought better ones locally)

Hopefully, the pictures came thru. Showing both sides of the PTO pump. With these, it is super easy to connect / disconnect the pump completely. So, now you can hold the pump without any hoses attached, dump it out, clean it, and in my case after cleaning I fill it full of RV (non toxic) anti - freeze spinning it by hand to make sure it's full.

Follow-up: I just recalled something. That is/was, the inlet and outlet hoses are different diameter. So the camlock connectors are not the same for each side. In my case, I simply called the place where I purchased the sprayer and they shipped me the correct camlocks. I did use Teflon tape on the threads.
Also, 5030: had said "If your pump is not stainless but cast, it's on borrowed time anyway. Roundup will eventually destroy it"
Been thru (2) blue cast pumps, latest pump is "Hypo silver series" roller pump. I never sprayed Roundup using my cast iron blue pumps, but they still went bad. However, at that time, I did not have the camlocks which made "really cleaning out the pump" almost impossible. I say this because I was NOT willing to un-screw plastic fittings to isolate the pump and instead tried to rinse the tank then run clean water, then add the RV fluid. What a pain ! Plus the amounts of RV fluid I needed to fill all the hoses and pump... Just did not work for me. The cast iron pumps really really need to be cleaned out well otherwise they will corrode and fail.

Actually called 'Banjo' fittings.

Correct... after you said that, I recalled hearing Banjo mentioned. Or Banjo Camlock, or... who knows what else

The inherent issue is, unless the roller pump is compatible with Roundup (stainless rollers and body), the pump will fail. Cast iron pumps are not compatible with Roundup, well they are for a while but longevity isn't in the cards.

Thanks, Spike!! This looks like the best solution I have seen so far.

Could not agree more ! IMHO, the cast roller pumps WILL work, but like a cheap garden hose, it is just a matter of time until it doe

Trook,
What type / model of pump do you have ? As 5030 said, and I could not agree more, if you have a cast iron roller, just be prepared to upgrade if you spray a lot of roundup. It is very acidic. But try the banjo camlocks. Makes a HUGE difference, good luck.
