"The Nautilis II" model offers:

Exceptional simplicity in setup, with precise electronic control of sump liquid level.

2-Channel Dosing Included - The Nautilis II comes complete with a 2-channel tubing set, which will allow you to dose BOTH components of a 2-component system simultaneously. It's capable of dosages from 7.2 mL/DAY up to 1/2 gallon/day.

Exceptionally quiet - quieter than your computer is right now.

Self-Priming; also anti-siphoning when not running.

Timer/Controller Compatible- Using the controller interface for timer or pH control enables the user to have the pump be controlled by a timer or pH controller. The pump remains on, but will run only when the controller is energized. See:Accessories

Float Switch Compatible - Low voltage float switch accessory controls the pump's operation. The optional float switch uses only 5 Volt transistor-level voltage from pump to float switch, offering very long life of float electronics as well as assuring personal safety. Float switch can be easily adjusted for changes in system through wing nut assembly (vertical support is slotted for precise adjustability). Unit comes with 3 feet of connection wire to provide flexibility and easy setup. No holes in sump housing required for float switch installation. For float switch, see :Accessories

Tubing for the high-volume tubing set is a long-lasting peristaltic tubing material which gives higher flow rates without putting excessive strain on the motor or gear assembly. Feel free to email for specifics.

Adjustable flow rate in single-channel mode from 5 to 850 mL/hour (up to 4.5 gals./day) prevents pH shock to the system.

Comes complete with two-channel tubing set for precise 2-component additions. (Single-channel high-volume set can be substituted for the two-channel set upon request). For float switches, timer or pH controller interface, spare tubing or other accessories, please click here: Accessories
