Noob pump question

@Innocentbystander whats been your experience with the banjo strainers?

Yup! Been a tough week.

Never owned one. I can’t fathom how they would work. Especially if you hook a garden hose to it and for water backwards into it.

Lol, logically it would work if you seal the threads that is :slight_smile:

Possibly unnecessary under normal conditions, but just forces the supply through a 20 mesh (I think) strainer to keep any tank settlement out of the pump. That plug can be pulled to let the supply run straight through the strainer tube and clear out the filter too, so sending water into it would have the same effect as water coming from the buffer (or theoretically push into the bottom of the buffer if the pump didn’t let it blow off). Seeing as there was (best I could tell) absolutely nothing in there after a solid year, I’d agree that it probably is unneeded.

Oh, you need a filter, I use the canister ones. I just don’t think the banjo filters work as well and they don’t look like banjos. I have ways about me that don’t always jive with other’s thinking, but they are clear to me. Calling something a banjo filter when it doesn’t look like a banjo seems disingenuous.

as long as the Banjos don’t start dueling, I’m OK with it…

So long story short, I’ve got these things (well 1 so far, but know the issue) up and running again, but nothing I do will work with the unloader. We’ve put on the old white tip (which I assume is the one that came with these machines last spring), and I crank the unlader from top to bottom and have a constant garden hose like flow of at least a couple gallons a minute or more…New unloader (AR VRT3-250 Blue spring/3650psi on a 8/3500 machine)…anyone have any insight? I can’t understand why this isn’t working…

Pics of unloader and set up now, including bypass my what is bypass doing when you try to adjust unloader

This, except I moved the water intake to the right hand side of the pump, and the bypass line out of the side of the unloader facing toward you in the pic…otherwise, this is exactly it. It’ll be back here in an hour and I can retake if needed, but hoping to have some clue why it won’t set.

I can try and get a video, but basically the flow never decreases at all as I tighten it all the way down, or if it does it does so slightly. It’s a pretty solid few gallons a minute out of the bypass at a minimum when I was running it into a bucket last night. So I stuck a brand new one on there and same result…

I’d like a close up pic of the unloader. I don’t think it’s plumbed right.


I’m a pretty big idiot some days, but they’re pretty idiot-proof aren’t they?

As long as you do like the injuns and follow the arrows. Just trying to start with the simple stuff and work thru it. I assume you got the proper tip, probably a #9 for your machine. It’s a pressure unloader so you aren’t going to get anything going without a pressure tip. All else fails, call MVP and ask for Diego. Tell him I sent you or he may hang up since you didn’t buy it from him. He’s the smartest guy I know in this industry. [Name] Mvp

Yeah, the tip is the only thing I’m unsure of at this point…may run to the local supply house and grab a #8 or #9 (my calc said 8.5) to be sure… doesn’t matter what pattern it is, correct?

Pattern doesn’t matter. don’t worry about a gauge for now, or every if you’re me. Just get the bypass to a trickle and roll with that.

yep, have a gauge just in case…but I think setting it to a trickle of bypass at max pressure makes the most sense…so many factors can go into how these things function, and that method will be setup/machine specific every single time.

I’d go with #9,

That’s what I grabbed…got a #6 for my 5.5s too :wink:

So the tip solved the unloader problem…she’s heading out for field testing tomorrow. The wash trailer is still going with her though, just in case… :crossed_fingers:

Good stuff @Innocentbystander. :clap:

Unfortunately it’s now spraying gear oil (I think) everywhere…I think a seal got lost in the process of it falling apart :confused:
