Hello, Wrenchies~ I supplied the Grundfos SQFlex 11 SQF-2 helical rotor pump to a client back in the good old days before dear Grundfos decided us solar guys weren't good enough to shepherd their pumps.
Serious drought caused the well to dry up; the pump got pulled but did not get a rinse-through with clean water. The mud inside the rotor dried out and cemented the rotor in place. I think the motor is fine but is repeatedly going into self-protect mode since things won't turn. My client needs a repair that I am not qualified to handle since...after all...I'm just a solar guy not good enough to receive customer support from the Mother Ship. ++++++++++++++++++++++++++++++ Authorized Grundfos pump guy #1 opened things up, declared that the machined rubber volute was chewed, and he offered to install parts from his shelf, but his parts were for model 6, not 11 so the gallons per minute would go way down. Authorized Grundfos pump guy #2--the wholesaler in El Paso from whom I originally bought the pump--says these are never repaired, just replaced and of course for close to $3000. +++++++++++++++++++++++++++++ Non-authorized pump guy me finds the universe to be absurd at times but not this absurd...surely not this absurd... So there's my dilemma of the week, Friends. Kindly point the way to any shop that could repair this problem child.
