Will this pump go on neutral when you close the valves?

This pump is pneumatic. The material is pushed in one direct when the air valve is turned on.

Where woukd i find a rebuild kit for this pump if i needed one? Any part numbers or kits?

I am having the same problem no parts available as far as I can see I have been searching for hours and still no luck.

rebuild kit for qpk15?

Just because you put a question mark at the end of a statement doesn't make it a question. I recommend looking at previously answered questions. This is a cheap Chinese clone of an industrial pump. If you need rebuilt kits, buy a pump from a pump supply company.
