2" vs 3" chem handlers

[shtferbrains]

6.5 will be good for pumping water

Try keep your suction as straight and short as possible.

3in hose is a challenge with one arm.

There was a local one armed man who ran a standard vacuum truck doing everyone's septic tanks etc. didn't seem to slow him down at all.

Put a front load on your sprayer.
Nose right up to trailer.
Hose can be rather short.

We bought a 3-in chem handler this year. But my tanks are limited to 2 in outlets. Plan is to put 3 in cam locks on the 2-in pipe fitting. If the tanks have 6 to 10 ft of head, will 2-in restriction defeat the additional capacity of the 3-in pump?

My math says it should be irrelevant. But some real world experience would be appreciated

It will be slightly faster, but you can only flow so much through 2 in.

Change to 3in bulkheads and valves to see true 3in performance.

Your 3in pump will be starving unless you draw on more than one tank at a time.

But once you get to the bottom of the tanks they unload unevenly so you will be drawing on one tank for awhile.

If you have 2 tanks connect them to a 3” tee, problem solved.

Those pumps don't suck, only blow.
Banjo fittings aren't cheap. $5k on our last trailer build.
But when you need them.
All flange fittings. Never pipe. Never a 90° anything, but a sweep.
All tank supply run under deck up to a central manifold beside handler. Air supply to push out drain the stinger. Electric chem pumps with meters. We removed that venturi stuff. Reworked handler manifold.

In answer to my question. Didn't even try it with the 2-in fittings. Cut a new hole in the stationary metal tank in the yard and welded a 3 inch fitting into it. Cut a bigger hole in the nurse tank and put a 3 in bulkhead into it as well.

Impressively fast fill now.

We bought a new Pattison Inductor with the meter and 13.5 HP motor. It's fast. Blazing fast. From the moment I pulled up for the water tank to completing a fill was 12 min on 1650 gallons. Including pulling 120 L of glyphosate and 20 of goldwing from drums.

This allowed me to do 4 loads this morning before the wind got up. With the other system I would have gotten 3 loads done. So a extra 160 acres. If there was 10 windy days in a row I would have an extra 160 acres done per day or 1600 acres. Which is 25% of our acreage.

I would never consider a 2" fill hose and a 3" pump. Likely a 40 min full then.
