The Neptune Systems DOS (DŌS) is a precision dosing and fluid metering system with dual peristaltic pump heads, driven by industrial gearless stepper motors for quiet, accurate operation. It delivers variable flow rates from 0.1 mL to 250 mL per minute and is controlled through the Apex ecosystem and Apex Fusion app for automated dosing, additive delivery and continuous water changes. The current QuietDrive version uses sure-fit compression fittings and large-diameter tubing for reduced wear and quieter running.
