DOS QuietDrive Dosing Pump

The Neptune Systems DŌS QuietDrive is an ultra-quiet, precision dosing pump engineered for Apex A2 and A3 Series Controllers. Featuring QuietDrive technology that reduces operational noise by up to 400%, this system automates two-part dosing, water changes, and micro-dosing with unmatched accuracy—down to 0.1 mL increments. Run continuously at low speeds (up to 25 mL/min) for stable additive delivery, or perform automated water changes up to 113 litres daily. Water-resistant backlit priming buttons simplify operation in tight spaces, while 1LINK connectivity eliminates external power supplies and reduces cable clutter. The redesigned dark grey finish complements modern Neptune hardware. Manage everything through Apex Fusion cloud interface for complete scheduling and calibration control. Includes tubing, graduated cylinder, and 1LINK cable. Requires Apex A2 or A3 controller.
