Agitator nozzle for Fimco sprayers

and I am getting happier each day.

(Prices vary on the web, but I got a great
price from Gempler's.)
There is room for improvement that the end
users has to deal with on their own.
My #1 priority was to improve circulation in
the tank using the pump bypass outlet. The
factory outlet is just an open port that does
little or nothing to promote circulation
depending on your pressure setting.
I replaced the Femco 11/16" fitting with a
3/8" to 1/2" barb that I got from the local
big-box store. I threaded on a Lechler
agitator nozzle (pn. 500.262.53.02) and it
made a world of difference! I strongly
recommend this modification for anyone using
a solution that wants to separate in the
tank. The nozzle is an induction style
design that really moves the solution around
with very little water pressure. (You can
order the nozzle directly from Lechler
http://www.lechlerag.com/ with a phone
call.) Here's a data sheet from another
vendor:

The 3/8" replacement fitting has a small
shoulder and doesn't seat well against the
tank, so I enlarged the hole in a nylon
washer. Using the nylon washer eliminated
the need for a rubber gasket. The nozzle
threads on inside and eliminates the need for
a nut on the inside. You'll need a helper to
do this since Femco put the fill hole on the
opposite side of the tank as the pump. (Doh!)
I also added vertical booms to the spray arms
that required me to reinforce the support
brackets. I'll cover those later.
