Frequently Asked Questions

  • Tighten stator to achieve suitable pumping pressure.
  • Loosen stator to achieve suitable pumping pressure.
  • Tighten stator. 
  • If low output continues, replace stator.
  • Tighten stator. 
  • If low output continues, replace stator.
  • Clean or replace the material hose.
  • Clean or replace the applicator or tip.
  • Reduce hose length and/or increase diameter.
  • Evenly loosen the stator bolts to reduce pressure. 
  • If the pump still does not operate when bolts are loose, engage the jacking screw (JS) to further open the stator sleeve. 
  • This should reduce pressure enough to allow the pump to run. 
  • Once running, re-tighten the stator bolts to achieve appropriate pump pressure.
