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

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.

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

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

The media could not be loaded. I been using the same model pump since 2021 for softwashing and they usually last anywhere from 6-8months but the pass 3 I’ve had only held up for few days of few weeks. They all almost immediately start leaking from the diaphragm and all ways end up leaking inside the motor housing…. What is going on with everflow ? Quality has dropped that bad ? They used to work for minimum of 6 months with not leaks on the pump. Usually the motor would get tired and just not put as much gpm so i would swap for a new one but now the pump seals are just not holding up. And I have to wait almost 1 month to receive a replacement? I’m currently looking for another brand! I all ways kept a spare pump in my trailer the only problem is I rant out of spare pumps and still everflow has not even shipped the pump I ordered 2 weeks ago.

Purchased many 7GPM Pumps from everflow through out the years and now they changed how their pumps are built. The new version only lasted me about 4 months.The older model lasted about a year maybe a year and a half.Writing this from a softwash job I’m at right now and the pump decided to kick the bucket midway through. These things aren’t cheap, so to be spending 260$+ every 4 months adds up

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.

I have installed it in my backpack sprayer fit extremely well hooked up and ready to use just waiting on spring to come to see how well it works
