Black Gold Pump & Supply, Inc.’s Chemical Injecton Mandrel allows producers to contnuously or batch treat wells at any locaton in the producton tubing string.


The Chemical Injecton Mandrel allows producers to fght against corrosion, parafn, wax, scale and mineral build up in the producton tubing and downstream. Other methods of injectng chemical require pulling of the pump and/or rod string, while this mandrel is set when running the tubing in the hole. With an 8RD EUE Box end on either end, this mandrel is installed like a tubing coupling.


The mandrel features a 3/8” NPT Box end connecton for easy connecton of 1/4” or 3/8” Capillary tube accessories. It’s single piece body comprises no welds or ftngs, eliminatng potental leaks due to manufacturing defects. It’s large bypass area prevents sand from building on top and gas slugsfrom forming below and allows tools to be run past the mandrel when  needed. The mandrel features a large beveled botom allowing the tubing to be freely run down hole.

  • Contnuous or Batch Treatment

  • Inject Chemical Where it’s Needed

  • Protect Rods & Tubing from Corrosion/Scale
