Everflo EF5500-BOX 5.5GPM 12V Diaphragm Pump-1/2 FNPT Connection, 5.5 GPM, Black

Replaced an older pump that was still working on an Irontron 8 gallon ATV sprayer. The older pump had lost some pressure and this one works great. Total replacement time might be 10 minutes. Unit is very quiet. When I use this unit I usually spray fire ant killer, 2-4-d, or Roundup. Clean the unit after each use!!!!I get amused by people who rate a pump as not lasting very long but works good when it did. I have to believe that many users do not clean the tank/pump after each application. I learned the hard way, but now I do not have any issues with pumps. There is not a pump sold that will withstand harsh herbicide/pesticide chemical on the interior seals. If you clean the tank/pump after each use it will last a long time. Here is what I do:1. Drain the tank of any remaining fluid2. Add water to the tank and then drain it again3. Add about 2 inches of water to the tank, power up the pump, and spray the water out4. When the water hitting the ground loses the suds or soapy appearance the unit is now spraying mostly water.5. Unpower the pump and squeeze the lever on the wand to remove the pressure inside the pump.6. Store the unit for the next use. I always leave some water in the tank, but not in the pump.Good luck. It only takes less than 5 minutes to clean.

Ordered for my husband. He said it worked perfectly.

My previous review was not rosy because the new pump failed to start! Unfortunately Amazon return timeline expired already! Fortunately the manufacturer in Minnesota “Valley Industries” was incredibly kind. Thank you Mary! They sent me a new pump in 2 days because the pump was still under warranty.So have no fear the folks at Vally industries will be there for you.

Why did you pick this product vs others?:I chose this item as it was identical with mine that quit. Upon receiving it , the hose connections were completely different. I had to disassemble the top of the pump along with the old pump and switch the hose connections.

Purchased this and did everything possible to use it as a soft wash pump. I can only use long range tips, not fan tips. The stream when first purchased was pulsating. It's suggested to turn the psi screw. This was adjusted and it worked fine for about 45 minutes, then nothing. I have used a 12v group 24 battery, that sucked. I used a 16.7 12v waterproof charger, it was a bit better. The pump stopped working in the middle of my job and I noticed the pump would not kick on. I checked the pressure switch and it was faulty plus I noticed a crack in the plastic housing, complete junk. The power switch is supposed to push out when the pump lacks the correct pressure and then push in to stop pump when pump is not in use or has adequate pressure. The switch is not closing the circuit. After releasing pressure it takes 10 sec to kick on, so a faulty switch too. The screw can't be turned any tighter for pump operation frequency without striping or falling into the housing. The whole power switch and housing for turning the pump on and off seem like complete plastic junk.

My north star broadcast sprayer was working intermittently. Purchased this and it was a direct cross with all the same connections. Undid 3 screws and this was put right in its place. Connected the battery and I was back to spraying. A 5 minute fix.

A true value and fast shipping was excellent option and avoided a long ordering process for our farm equipment.

Works great. Installs easily
