Neptune DOS Quiet Drive Dosing Pump

DŌS QuietDrive – Dose. Automate. Protect.

• New QuietZone Modes for Reduced Noise.
• New Continuous Duty Modes.
• Same Reliable DŌS Hardware.
• Compatible with A2 and A3 Series Apex Controllers.

In the most important ways, this is still the same Neptune Systems DŌS that reefers have come to know and love. The Neptune Systems DŌS QuietDrive remains a highly efficient, programmable dosing system designed to work seamlessly with the Neptune Systems Apex Controllers. Ideal for a variety of dosing applications, it offers precise control over dosing volumes and schedules through the easy-to-use Apex Fusion cloud interface. The DŌS QD pump features dual pump heads, large-diameter tubing, and simple maintenance with easy tube replacement. It’s a practical solution for accurate and consistent aquarium dosing, minimizing manual work and maximizing reliability.

So, What’s New with the DŌS QuietDrive?

 Quiet Operation: The DŌS QD incorporates EcoTech QuietDrive technology to significantly reduce noise.

• Up to 400% reduction in noise at high speeds (60/125/250 ml/min).
• Up to 200% reduction in noise at slow speeds (7/12/25 ml/min).

Continuous Duty Operation: At speeds up to 25 ml/min, the DŌS QD can run continuously, allowing the pump heads to run more quietly and offering more flexibility for additive dosing and automatic water changes.

Priming Buttons: The priming buttons have been changed from plastic to backlit with R and L indicators, allowing you to easy see what you’re doing, even if you’re working in a dark aquarium stand. They are now water resistant, which helps prevent damage to the DŌS QD if you press them with wet hands.

Powered by 1LINK: Say goodbye to the power supply. The DŌS QuietDrive includes a 1LINK cable, which connects directly to the EB832 Power Bar. This single cable powers the DŌS and links it with your Apex Controller, cutting down on the number of cords and freeing up a standard plug on your EB832.

New Look: Last but not least, the DŌS QD has been re-styled in a dark grey color similar to the Sky LED, giving it a bold new appearance. 

What Can the DŌS QuietDrive be Used For?

Two-Part Dosing: The most common use for the DŌS is dosing calcium and alkalinity to your system. Using a dosing pump to add these elements means greater stability of important water parameters and less daily maintenance. Simply run the DŌS Additive Dosing task in Apex Fusion and enter the amount of liquid you’d like to dose and when you’d like for it to be dosed. The DŌS then sets up all the dosing intervals within that time period.

Automatic Water Changes: Water changes with the DŌS QuietDrive have never been easier.  All you do is run tubing to your empty vessel or drain and to your fresh stock of saltwater. Then, in Apex Fusion, select and run the DŌS Automatic Water Change task and you’ll be up and running in a matter of minutes. It will perform an automatic water change for you based on the schedule you’ve set up. It’s possible to change up to 30 gallons per day, or 12 gallons per day in the “Quiet Zone.”

Micro Dosing: If you need to dose tiny amounts liquid (like vodka dosing or for Zeovit systems), the DŌS is the perfect solution due to its precision-controlled stepper motor. This ability to control pump movement in such a refined manner means that you can dose as little as 0.1ml at a time.

Easy Maintenance and Tubing Changes

Changing out the pump head on the DŌS is a snap…Literally! All you need to do to change out the pump head is squeeze and remove. Then attach your dosing tubing to the new head, and snap it back on. No screws, no fuss.

Specifications

• Size, approximate: 9.5 × 5 × 5 inches (24 × 12.5 × 12.5 cm).
• Weight, approximate: 4 pounds (1.8 kg).
• Flow rate: variable, 0.1 ml to 250 ml per minute. The smallest single dose is 0.1 ml.
• Continuous duty: at speeds up to 25 ml/min the pump can run without a rest cycle.
• Lift height: 24 feet (about 7.3 metres), minimum at sea level. Suction height: 24 feet.
• Water changes: up to 30 US gallons (about 114 litres) a day.
• Power: 24 V DC, taken over 1LINK from an EnergyBar 832, an EnergyBar 632 or a 1LINK module.
• Drive: gearless direct-drive stepper motor, 5,000-hour mean time before failure.
• Fittings: sure-fit compression fittings on 6 mm outside diameter tubing.
• Requires an A2 or A3 Series Apex controller.

What’s in the Box

• DŌS QuietDrive pump.
• 50 ml graduated calibration cylinder.
• 6 mm outside diameter dosing tubing: Neptune’s setup guide puts the supplied length at four metres, to be cut to suit your run. Longer 4 m and 16 m lengths are sold separately.
• 1LINK cable.

No power supply is included, and that is by design: the QuietDrive takes both power and data down the single 1LINK cable from an EnergyBar 832, an EnergyBar 632 or a 1LINK module, which is what frees up a mains outlet on the bar. If your controller has no 1LINK port (the A3 Apex Jr has none), Neptune’s setup guide covers the alternative: a 24 V power source and a 6 foot AquaBus cable, both sold separately.

Pump heads are a replaceable consumable and are not spares in the carton. Changing one needs no tools: squeeze, pull it off, move the tubing across, and snap the new one on.

Safety & Precautions

• Mount the DŌS above the water line, and put a drip loop in every cord and cable. Neptune are blunt about it: water damage to the module voids the warranty.
• Keep your dosing reservoirs below the pump. A container sitting higher than the DŌS can gravity-siphon its whole contents into the tank if the pump head ever fails.
• For the same reason, finish the outlet tubing just above the water surface. Never leave it submerged.
• Bring the Apex up to current firmware before you connect the pump. An out-of-date controller will not run it.
• Never plug a USB device into an AquaBus connector, and never plug an AquaBus accessory into a computer USB port.
• Calibrate both heads before first use, one at a time, from the Apex display: Setup → Module Setup → Config Module → DOS Module → Calibrate Pump. Prime the head until the line runs clear of air, then let it run its 90-second cycle into the graduated cylinder (it is aiming for 40 ml) and enter what you actually measure.
• Read the cylinder at eye level, level with the liquid, and take your figure from the bottom of the meniscus. Reading it at an angle is the commonest source of a mis-calibrated doser.
• Re-calibrate every 100 hours of running, and any time you switch a head to a liquid of noticeably different viscosity.
• Mount it on the punch-out holes in the back or stand it on a shelf. The two heads are deliberately offset so tubing does not kink when DŌS units are stacked.
