I think the 11-2 is no longer made or no longer imported to the US
But most of the other normal SQF are available

I have used the SQF pumps for many years, and I’ve been very impressed with the longevity of them. When I put a pump 400 feet below the ground, the price of the pump is a small fraction of the overall cost, so I don’t mind spending a premium on a pump that I feel like I can really trust.
Just two weeks ago, I replaced one that broke that had been down there for many years, and what had happened was that a wire had corroded through, so any pump can have that happen if the wire gets nicked…
Anyways, when I picked up a new SQF pump from the master distributor, they did not mention it being discontinued or anything… when I asked if they had one in stock, they basically said “Of course.” So if you’re certain it’s been discontinued, I definitely would like to know. Perhaps, many places just stopped carrying it…
Thanks,

All,
Thanks for the help with this pump issue and sorry
about the pump leads to ground comment, I meant to say they both
tested "open". Yes, there seems to be a wide variation in prices
associated with unknown quality/time-tested reliability. Once I
throw a pump down a casing, I and I'm sure my customer, don't want
to see it again for long time. I'll check into the resources
given here to my query.

Backwoods solar is now selling their own progressive cavity and
centrifugal pumps. Might take a look at them.
The SQF series pumps had a VFD drive and MPPT built
into the pump motor -- no welltop controller was
actually needed, except to integrate float switches
into it, switch between different sources, or show
what the pump was doing. But it would run with 30 to
300 volts DC applied directly to the power wires, or
90 to 240volts AC, no controller. Because of this,
you can't measure the windings of the motor directly
on the output leads like a pump that has just a motor
on it.
I did not realize that they were out of production
now. I know there are a lot of cheaper chinese
variants out there now at half or a third the price of
a SQF, but I have not tried any of them yet. Most of
the ones I've looked at specs for are a bit more
limited voltage input range compared to the SQF's
though.
