I salvaged the circuit board, motor, and air bladder from a previously working jetpaq pump. The mechanical seal failed on the pump, and NO parts are available from Grundfos. I tried to fix the mechanical seal, but my fix altered some critical clearances between the impeller and the the pump housing that did not manifest under manual operation. The impeller welded to the housing making the rendering the pump beyond repair. Hey....you win some you lose some. 

Hopefully these parts may rescue a Jetpaq pump some day. 

Who knows their street worth since no parts are available. I don't want to separate the parts, and I am guessing the board, motor, and bladder should be worth about 150 bucks.
