ABSTRACT:
A ball catcher is adapted to be fluidly connected to a wellhead port to receive wellbore fluids and balls carried therewith. A diverter is fit to the catcher body and has a wellhead end positioned to intercept the fluid flow from the wellhead port so as to divert debris and balls carried therein into a ball recovery chamber. The diverter has a bore in fluid communication with the flow outlet and the wellhead end has flow passages formed therethrough to the bore for receiving the fluid flow free of debris and balls and discharging the fluid flow from the catcher body. The diverter and the ball recovery chamber can be connected to quick removal for replacement, repair or cleaning.
