SHURFLO2088-343-135 Automatic-Demand Diaphragm Pump, 12VDC, 45 PSI Demand Switch, 3.0 GPM With Viton Valves, Santoprene Diaphragm, Self-Priming, 10 AMPS (Max), 1/2"-14 NPSM Port

Works great for my application

Pumping water from 12-15 foot depth. Into a wildlife pond for about 45minutes daily. So far it has lasted all summer and into autumn.

Shurflo pumps always work great. You won’t go wrong.

UPDATE : 9 months and it’s dead. Smoking from the top near the connections. It’s been sputtering and pumping intermittently for a few months though. So I guess it worked well for 6 months of light use. Trash! I ordered this because I had Shurflo before, but I’ve given up on Shurflo this time.My last pump was a bypass pump, which was much quieter and didn't kick on & off constantly while running water. That pump is apparently no longer made (or is not sold on Amazon) and I thought this may be the one they replaced it with. But this one is not a bypass pump, so it kicks on & off constantly. And it is much louder than the last one. I probably will not wait for another CO winter to destroy this one, before trying to find something quieter and hopefully a bypass pump.

Well made but noisy.

Used for agitation of a fertilizer tank worked perfect. Needed to put a weatherpack connector on it but no big deal.

Set it up to work with my pressure washer using a 300 gallons tote. Maintains pressure.

Was a perfect replacement for the old pump on my sprayer that I had for many years. Exact model made the installation easy. Worked first time with no issues.
