Gary,<br>
What I suspect may be at issue is the wire. Shurflo requires
jacketed cable (10 or 12 AWG) of a particulat dimensional range. The
issue is that few suppliers carry the right cable. It's a Code issue
- any pump with a metal case requires an equipment bonding conductor
(silly, I know) which means three conductors, which won't fit in the
cable gland. Having a nonconductive plastic case, the 9300 only
needs two conductors, will only fit two conductors, and no pump or
electrical supply house carries two-conductor cable because nothing
they sell uses it. Sort of a catch-22.<br>
<br>
Also, using unjacketed (yellow) multiconductor cable is a guaranteed
way to get water into the motor.<br>
<br>
Hope this helps. <br>
Allan<br>

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

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

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

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