Pressurized hand sprayer

Cornflk1
I'm looking for a 1 -2 gal hand sprayer for weed killers that I can pressurize with a air compressor to about 60 psi. All I seem to find are back-pack units or ATV types. ( Too heavy - already have one for UTV )

I'm tired of buying cheap hand sprayers that that after a year, I can't pump it to 5 psi. I remember the old days when the pump was made of brass and it would pump to 50/60 psi.

Anyone have a web site ? Northern Tool Co. catalog and my first web search didn't pan out.

Thanks in advance.

    Someone is going to suggest drilling a hole and putting a tire valve in.

    When it goes "BOOM!" you're going to have a face full of poison.

    drill a 1/2 inch hole and put in a tire valve, although i think 50psi is a bit ambitious.

    I have a SS 2 gallon tank that I put a tire valve in 30 years ago. I made a SS plug for the top and regularly put 100 psi in it.

    So far for 30 years it has not done anything but work well for me.

    We bought a couple of "fill and pressurize" fire extinguishers to use around the combine. You can run up to 50# or more of air pressure but I can't guarantee how long the seals and valves will hold up to chemicals.
    The main problem with using air pressure is that as the liquid goes out the air space volume is increased as the pressure is decreased. Putting 50 PSI in the tank doesn't mean you have 50 PSI when the liquid is 1/2 gone.

    Also my experience, when having to use a SS H20 fire extinguisher.

    I also have a high end Wolman deck sprayer. All Brass hardware.

    Just last night, spent a little time refurbishing the on/off squeeze valve/lever. Disassembling it, removing all rubber O-rings, lubing it.

    It has been an awesome unit.

    It is apprx. 12 years old.

    Will be using it here in the next hour or so.



    Just came in from running a couple gallons through it. Performed like a champ.

    Heading out back to run another gallon through it.

    Ranger Pro. An industrial grade of Roundup/glyphosate. Used it industrial, when I had a Commercial Applicator's License a few years back.


    While I would love a backpack pump model 2-3 gal. unit. I really do not need one, for the amount of spraying I do here in my oversized yard. (2-3 acres.)

    I do not mind pumping it up every so often, I can not imagine needing a SS unit capable of 50-60 psi.
    Would it be nice? Yes. Would it be needed? No.
