Way over budget but you can get all the parts for them.You will only have to buy once . I have a couple already built if you want to borrow one if you have a "one off" job. http://www.allpumpsdirect.co.uk/Comet-MC18-2-Diaphragm-Pump-6127000400-15-Bar-11.9-Lpmhttp://www.ebay.co.uk/itm/Honda-Gx-160-Engine-/151523066275?pt=UK_Cars_Parts_Vehicles_Other_Vehicle_Parts_Accessories_ET&hash=item23477a81a3These are also worth looking at if the mix ratio's are vital...but I think they only mix to about 4%. The good thing is you can join to a hose pipe ,set the solution and it mixes as you spray. It compensates for flow and pressure. You have very little waste of your chemical...unlike mixing a set amount in a tank and spraying were you always mix too much or too little.http://www.dosatron.comI have one set up for spraying Quats.or http://www.ebay.co.uk/itm/Pedestrian-Boom-sprayer-lawns-pitches-/201245645426?pt=UK_Home_Garden_Garden_Plants_Fertiliser_CV&hash=item2edb2cda72You will need a lance and waterfed pole.
I have made my own 12v pump box for pumping chems. I havent tried it with acid mind.It cost me around £35 all in. It just draws the chems from a 25ltr barrel.If the pump goes bang I will put another £10 pump in. I keep a spare in the van.So far I have had easily 30 days pumping with it and its still going fine.
