Replacement pump for spray tank. Works great.
Reviewed in the United States on October 13, 2025 by Marty H.
We had a broken hot water pipe under our foundation, and no hot water for weeks. I bought this for a quick shower setup. This review is for the the 1.2 gal/m model. It's a diaphragm pump, of course it makes noise; volume increases with load. It's a lower frequency buzzing/vibrating sound which gets amplified if the pump is mounted on something that resonates. The actual noise volume is pretty low, but it drones and I can see how people might find it annoying. Mount it in a foam box and you can barely hear it. The feet are rubber, and mounted on a dovetail. They don't "break off" as other users posted. If they fall off, you just slide them back on. Good design. They help with damping the noise. The connectors do not leak. If they leak, it's because of incorrect usage or a defective unit. I used 3/8 medical grade silicone tubing for pickup and output, and a single zip tie on the output side; no clamp on the input side. Zero leaks. A zip tie worked because I had minimal pressure on the output side with a shower head. I tested with full pressure though by putting the shower head in trickle mode, and still no leaks. It handles shower temp water no problem - about 110 degrees F. Power usage depends on load. It draws less than 1 amp while showering - around 10 watts. Again, power usage increases with load, so you will see full power draw at full capacity. I am using this pump for a makeshift shower, as we have a major plumbing issue in hour house which will take weeks to fix. It's connected to a standard shower wand (a spare one I had), and I use a 12 gallon tank that sits in the far end of the tub. Power comes from a small-ish power bank through a 12v cigarette lighter plug and a waterproof switch. Works fantastic. Waaaay better than one of those battery powered camp showers, easily twice the flow and pressure, and gives you a "normal" shower experience using a normal shower head.

I purchased this Bayite 12V diaphragm pump as the core component of my DIY backpack sprayer. I wired it up to replace the manual pump mechanism on an old Harbor Freight sprayer, and it's been successfully spraying chemicals for pest and weed control. The pump works okay for light, intermittent spraying. It puts out a solid stream at 12V, and the included hose clamps were actually a helpful addition. However, I've run into an issue when spraying continuously. If I spray non-stop for over a minute, the pump starts to bog down and the pressure noticeably drops. I did my homework and checked the usual suspects: It's not a battery/voltage issue; my power is steady. It's not a vacuum issue; I made sure the air intake has no restriction. I'm giving it the benefit of the doubt—it might be an interaction with the step-down converter I'm using, or maybe the pump itself simply isn't designed for sustained, heavy-duty pressure. Either way, I've adapted to its limitation by simply taking 20-30 second breaks after a minute of continuous spraying. If you plan on using this for quick, small jobs, it’s fine. But for large, non-stop areas, be aware of the duty cycle limit.

I bought this pump to replace a 'd' battery pack/shower pump for an instant hot water camping shower. The original pump is pictured, i found out that it had taken a crap on me when I checked it prior to a week long camping trip. I looked at tractor supply for a pump, one similar to this was 70$, no thanks. Took a chance on this little unit and it is perfect for what I needed it for. I mounted it in a plastic ammo can with stainless hardware, an inline fuse and a simple on/off rocker switch. Easy peasy. As far as shower pressure goes, it's pretty fast. The old pump was slow enough that a five gallon bucket was enough for two people to shower with. This pump cranks the water through it so fast that a five gallon bucket is enough for one person if you hustle. It does however have excellent pressure. So it's not a negative against the pump that it is fast, slightly inconvenient for me in that I would like it to be a little slower, but I plan on slowing it down with a pwm in the near future. I had it hooked up go a 12 amp hour battery and didn't have to swap it out over the course of a week. Maybe 10 showers between everyone. So it's easy on the battery. I dont have a use for the pressure regulator so I cant speak to how well that works. Overall it's a great little pump. I use it for a very specific use and it works great.
