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

The quick connect model is hard to find when trying to replace a Northstar 2272Q. This was an exact fit and I highly recommend buying it because of ease of installation and economical pricing.

Works great. Installs easily

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.

Exact replacement for my sprayer I let freeze. Works great.

I have been using these pumps to spray Roundup. First one had an issue with the relay, then started leaking. Second one had about 4 hours on it and just quit. Not sure why, and I haven't had time to troubleshoot except checking for power. No rebuild kit for this model seems to be available. I contacted Everflo and they responded with a list of a bunch of questions before considering warranty. No real help to get me back spraying. All I really needed was the rebuild kit to fix the leaky gasket, would even pay for it. All in all a waste of significant money and time. Imported junk. Actually the cheap harbor freight pumps I used to use lasted better, but weren't as strong. I thought this one would be the ticket. Bailing on this and going with a 3 point PTO pump.

Great Suction, user friendly for installing, durable build, strong pressure!

First pump was delivered with issues second pump was here the next day fantastic customer service I was able to get to the job site the following day pump work fantastic met above expectations would recommend

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.
