SHURFLO Stainless-Steel Accumulator Tank

I would recommend getting rid of the accumulator. Take it apart and you will see a diaphragm that is rotten. I used one for a while and threw it away after I found there are no replacement parts. I never noticed a difference with or without.

I kept the fittings this year but changed the o-rings. Otherwise they leaked. I tried my 12 volt system without the accumulator and do like it better with.

Had one years ago leaked like crazy....don't use one....keep it simple.

One of my guya "blew up" an accumulator after replacing a pump. Blew housing apart, gutted the bladder.

1 of 3 pumps he destroyed in 3 months due to not rinsing.

Now killed battery. He's spraying without the accumulator but worried he'll kill another pump?

Starting out I was taught to use an accumulator to reduce cycling of the pump thus extending the life of the pump. Some are suggesting in this thread to get rid of the accumulator. Any final thoughts?

There are better ways to keep the pump from cycling. If you have a Delevan you can adjust the pressure set screw to match the orifice size you use. This has always worked for me. Most times changing the size of the nozzles will take care of it. The funny thing about that "needed" accumulator is... how long have you been running the pump with a broken or cracked diaphragm? All worked well and you didn't know it was worthless inside with a bad diaphragm. In the past when I installed one for about 3 months, that was the all new next best thing. When I took it off and threw it away it was one less thing to replace or repair. Your call Dave. Who taught you to always use an accumulator? So much has changed since that was supposed to be a good idea. I'm finished... off to work!

I use an accumulator but it's only so I can use 20 orifice tips on occasion. If you use 30 orifice or larger than most pumps will work fine. Basically if your tips (without an accumulator) cause your pump to cycle rapidly, then use an accumulator.
If your pump just goes on and off when you activate your spray then I wouldn't bother.

When I had the tank hooked up I liked it. Worked good when using different shooter tips and stopped the cycling. I just got tired of the leaks and it braking. One less thing I have to fix.
