- W
  Wanda HudsonSep 7, 2025
  If you're experiencing under dosing with your DOSATRON Industrial Equipment, consider the following: * Check for air tightness problems, ensuring the injection assembly nuts are correctly tightened, and inspect the condition of the suction hose. For IE versions, also check the injection hose. * Inspect the suction valve seal for wear or dirt. Clean or replace it. * Address overflow (cavitation) by reducing the flow. * Replace a worn plunger seal. * Replace a scratched dosing pump body. * For IE models, check for damage or lime scale build-up on the external injection module and the injection T-piece. Inspect the condition of the silicone umbrella valves, the diaphragm, and the duckbill valve. De-scale or replace if necessary.
