    Why is my dosatron Dispenser under-dosing?
    • J
      Julia MooreAug 25, 2025
      Under-dosing in your dosatron Dispenser can be caused by several factors: * An airtightness problem. Check the tightness of the dosing part nuts and the condition of the suction hose. * A worn or dirty suction valve seal. Clean or replace it. * Overflow (cavitation). Reduce the flow. * A worn plunger seal. Replace it. * A scratched dosing pump body. Replace it.

    • C
      cschroederSep 5, 2025
      Backflow into the product tank of your DOSATRON Industrial Equipment can be caused by: * A dirty, worn, or missing suction valve or valve seal. Clean or replace the affected parts. * For IE models, a damaged injection module diaphragm and silicone umbrella valve. Replace the diaphragm and the valve seat. * For IE models, damage or lime scale build-up on the duckbill valve or silicone umbrella valves. De-scale or replace the duckbill valve and valve seat.

    How to fix under dosing in dosatron Industrial Equipment?
    • 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.
