when mine was having restart issues it was the mesh was a little to long. trim around it around the impellar. after that no more issues. before i did this banging it would kick start it though hehehe. but really just trim the mesh and its will be all good. or you can take it down to Reefgeek down in Carson and they will see whats wrong with it.
BTW after i trimmed the Mesh i got even better bubbles in the skimmer

trim it so the wheel and the mesh are even. no the mesh is there to chop the water and bubbles up. the thing is the mesh spins and spins and slowly it expands from the center to the outside. then it rubs on the out side of the pump body and it will stall it.

Trimming the mesh only solved my restarting issues on a BM 160 by about 10%. And I trimmed WAY down (like 40mm). What did work was to blow down the airline hose, or hold your hand in front of the pump's intake. Blowing down the airline hose is preferred, as holding your hand over the intake will most often saturate the skimmer with oils from your skim, altering bubble surface tension, and preventing a foam from being produced for up to a few hours...

I haven't read all the threads on this but I've heard it is a common issue which is pretty annoying considering the price of the pumps. I just switched out my mesh with needlewheels and it did not change the restart issue. I just ordered new ceramic shafts so we'll see if that helps. I'll give an update once I receive them.

it might be easier to get the pinwheel and you wont have to blow start your skimmer.

but the inside of the impellar is ceramic and plastic parts.

hmmm its weird for that to happen. i just took mine apart yesterday. i dismantle it once a month to inspect the inside also. and clean anything off the mesh to keep it on tip top shape. all pumps in tanks should be cleaned regularly every 3 months to inspect them to avoid problems like that. i have a Gen X pump with a damaged impellard also and it cracked it and started to rust. luckily i was able to pull it off my skimmer.

Wow thats bad. look like the inner wall around the shaft had a crack. You can see scratches on the magnet part all over. Also the mesh needed to be trimmed. it was probably putting alot of resistence on the pump and was not running balanced inside. The mesh is suppose to line up with the wheel all around. thats why some people have start up problems because they dont trim the mesh. Really sucks to loose all that SPS. Hey did you ever resolve your chiller problem with B.
