SEAFLO 22-Series Water Pump - 12V, 1.3 GPM, 100 PSI - On-Demand Water Pressure Diaphragm Pump for Marine, RV, Agriculture, and Off-Grid Applications

I was going to make a bucket sprayer like some of the other review pics show, but then decided to make something on wheels. I wanted something that I could use standalone or pull behind an ATV. I didn't want to have to rely on the ATV battery, so I decided to use DeWalt batteries. Amazon sells a battery mount that comes with a 20-12v transformer. I added an on/off switch between the battery and the transformer so it won't kill the battery when not in use. The pump and pressure switch work great. Very quiet and awesome flow and pressure. Much better than a pump up sprayer and much easier to user.

I bought this to put on a spray bottle so I don't have to keep pumping it up. I hooked up a battery to it works great.

This pump is much stronger a better built than what was originally on this sprayer. Only problem was the inlet and outlet ports were in different locations than the box and information supplied told. Message sent to manufacturer and never heard back. That is why it is receiving 4 stars

Pump is a great pump. seller delivered fast

Edit: Seller reached out and provided a full refund for the below reviewed pump. There was definitely a defect of some sort with my unit but after posting a review they handled it.Extremely loud, product description states no louder than a ceiling fan, that would be accurate if the ceiling fan was gas powered. Shook violently when in operation, and died in a month with a total run time of maybe 15 minutes, I haven't even gone on a trip yet, only used in testing after installation and to spray off a few things in the back of my truck. Contact email amazon provides for the seller comes back undeliverable, contact us on their website gets no response. DO NOT BUY!

This pump will pump at least three times stronger than the pump that came on the liquid tank spreader. I had originally rated this with only two stars because the box appeared to be opened and the product returned. The company quickly shipped me another pump in a box that was secure and accepted return on the first one. This is the kind of customer service that I expect from Amazon and its suppliers.

Put it on my tractor supply sprayer after the oem pump went out. Works great!

It did not come with an Allen wrench to adjust the pressure...nor was it marked on the pump orvin the instructions which way to turn....one had best guess without breaking it...
