John and Jay,
What Windy wrote didn't jive with me, so I called him to check. Indeed
there's an error, and Windy can address it later, as he was rushing out
the door when I called.
Sunpumps is the respected successor to Solarjack of years gone by. The
SunRotor was developed and is distributed by Solar Power and Pump,
http://www.solarpowerandpump.com. The rest of the info is OK.

Hi John / and Jay
Jay is correct to recommend that you consider Sunpumps or something
like that. To be more specific, Sunpumps has a line called SunRotor
www.sunrotor.com <http://www.sunrotor.com>. Along with Lorentz HR and
Grundfos SQF, these are HELICAL ROTOR (progressive cavity) pumps.
Eventually, I believe they will send Shurflo and other diaphragm pumps
packing to the scrap heap. They have one moving part / brushless motor
/ easy to service and in general, far greater life expectancy without
any demand for preventive maintenance like diaphragm pumps. Pump rotor
and stator will last many years if water is generally clean.
I’m including much about this in my upcoming book, so I’m pretty up to
date.
Lorentz and Grundfos are oversized when looking for replacement for
Shurflo, and they run 48V nominal and up. (Shurflo is 24V) SunRotor
has a niche in the low power end, starting at 24V. You may find
something compatible or easy to adapt to the existing system.
Several Chinese companies are producing helical rotor (HR) subs, so
you may find something if you search. When I search I get Alibaba
pages, from which you can order (like Amazon), but they don’t give
complete specs. They even get terminology mixed up and who-knows what
else. But from there, you can search the manufacturers directly by
name and make direct contact. OR You may find someone in your quarter
of the planet who distributes them, which is ideal.
At least SOME of those Chinese pumps are good. I can’t say which.
Hope this helps.

Hi all, can any pumping guys recommend a simple straightforward
replacement for the Shurflo 9325. The one in question has worked
faithfully for a number of years now and has already been repaired
once, but they don’t last forever.
Of course replacement parts availability is always important.
The 9325 was a good all ‘round inexpensive workhorse but the
application does not warrant replacing with a more expensive pump
like Lorentz, etc.
Thanks for any suggestions – John Veix, N.Z.

Hi John,
If you are looking for something similar to the 9325 but better then.
Check out Sunpumps.
Much better pump because of the superior case, cheaper, more
reliable and easier to repair
Also Sunpumps make some really nice LCB controls.
