Mac,
My experience is similar but slightly different. I have worked with the
Shurflo 9300 for nearly twenty years. I have closely followed the mfgr's
directions - even the temporary wrap of tape - and as far as I can
recall have had maybe one failure due to water penetration at the cable
gland. But I have seen a number of homeowner installs with this failure,
so it's easy to not get right. I agree that a fixed, sealed pigtail
would be a better approach, like a SunRotor, Grundfos or Lorentz.
The 9300 has a one-year warranty as I recall. Running open discharge
without float or time control, such as all day into a wildlife pond with
overflow, the pumps last about 1 1/2 years before needing the
diaphragm/drive kit and valve kit for a minor rebuild. If water never
reaches the motor, it will last through several of these lifetimes, but
usually folks don't do the service until the pump stops, and often a
failed diaphragm leads to water reaching the motor. But I have seen many
of these pumps go five or more years of intermittent duty needing nothing.
And the pump will run at less than half speed on a 12V battery. Standard
DC brush motor - speed and thus output vary directly with voltage.

Hi Drake,
I'll second Kevin's suggestion that it may be the waterproofing
gland. I see this as a very weak part of this pumps design and won't
ever use that pump again because of it. The aquatec SWP-4000 is a
very similar pump. Pump manufacturers should take responsibility for
the water-proofing into their unit. Under water splices are super
easy compared to the gland/grease mess routine required with these pumps.
As Kevin suggested, bypass the controller and put good ~ 24VDC down
there (using batteries off of your cordless tools works well for this)
These pumps will pump off 18-20V.
Good luck

Hi Drake,
We have a lot of these pumps in the field, operating without issue
for many years, though they are generally operating on some sort
of regular basis. But lots of customers with seasonal situations
that may have the pump idle for 10 months a year.
I would suggest applying 12/24VDC battery power directly to the
pump bypassing controller and see if you get any action, then can
narrow down if it is a pump issue or a controller issue. Another
issue is the waterproof gland if not done properly can result in
connection issues. Have had a few of those.

*Subject:* [RE-wrenches] Shurflo pump
Hello Wrenches,
A couple years back we installed a Shurflo 9325-043-101 water
pump. It runs array direct. After installation, it worked fine.
Since then, it has not been used. The client tried to operate it
recently,and it didn't work. A red light is showing in the controller.
How well do these systems hold up if not used?
I haven't gone out to the site yet, but wanted to get some
background from you water pumping guys about shelf life of idle
systems.
Thanks,
Drake
