QTY 2 Centrifugal Pump with Electric Motor (Small Set) - These are designed to work with my valve and fitting sets.   The tubing is 1/8" or 3mm on the suction or inlet.  The discharge or volute will we 1.8mm wire.   Look for my PFV sets to compliment your new pump.    Yours will NOT be painted NOR will it include the pipe or gate valve.  The painted version here is just for reference.  Some supports might ship in place.  Simply snip away with sprue cutters
