Innovative Aquatics Sentry Dosing Pump

IA1111

This item has been discontinued.

Innovative Aquatics The Sentry is a professional grade two- OR one-channel reef aquarium dosing pump that comes complete with all the equipment you need to automatically nourish, balance and protect the environment of your reef aquarium.

Two separate channels, pH Controller & Float-Switch compatibility. Large RED LED display, internal rechargeable backup battery, compact size, quiet, dependable performance dosing as little as 0.3 ml./hour up to 85 ml./hour when used to dose 2-part calcium/alkalinity additives. Also included is a higher-flow (3–800 ml./hour) one-channel tubing set capable of adding up to 5 gals./day. Can easily be used for either night-time only kalkwasser dosing, 2-component dosing or makeup-water additions.

Specifications
  • Two-Channel Capability Built In, with digitally adjustable dosing rates from .15 ml. to 85 ml./hour per channel when used with the included 2-channel tubing set.
  • Float Switch Compatibility. A float switch is available as an accessory, and can be plugged into the control jack in the back of the pump. The float switch is connected to transistor-level voltage, providing safety and dependability.
  • High Volume One Channel System. The Sentry is also made to be used as a one-channel makeup water doser. Using the included long-life tubing set, the Sentry will pump up to 800 mL per hour, or up to 5 gallons per day.
  • Controllable—Using the optional A/C control interface, the Sentry can easily be controlled by other devices, such as pH controllers, electronic float switches or aquarium monitoring systems.
  • 24/7 operation—Thanks to the Swiss-made motor and the Sentry is DESIGNED for 24/7 operation 365 days a year.
  • Accuracy and Tubing Life- by utilizing a heavy-duty, Swiss-made motor and precision gear drive system, the Sentry pumps at a constant rotor speed of 12 rpm when set at 300. For slower rates, the timing cycle is changed but the rotor speed remains constant. Since it does not rely on friction to drive the pumping mechanism, the output of the pump will remain stable over very long periods of time, and it’s also non-siphoning. Also, since the rotor moves at such a slow speed, tubing life is significantly better than that of higher-speed, gear-less pumping systems. Typical tubing life is 6 months for a two-channel system.
  • Built-In Battery Backup—The built-in nickel cadmium battery pack will power the pump for over an hour, providing peace of mind during power outages or in moving the equipment. The settings not only stay in memory, but the pump will actually run on the battery for over an hour. When turned off, the memory of the last rate setting remains in the pump electronics for 24 hours, so when turned back on, it rapidly returns to the previous setting.
  • Bright LED Display—Easily visible from a distance or underneath darkened cabinets. Quiet Operation. This pump runs exceptionally quietly, making less noise than most desktop computers.

REVIEW
Over the last 20 years I've owned many different dosing pumps in all different price ranges. I have gotten rid of them all and now own 4 of these wonderful pumps. These are the only pumps I will use on my 300 gallon reef, as well as the ATO on my 60 gallon cube. The Sentry is a no frills incredibly ...Read More

REVIEW
I bought this pump to dose small amounts of additives into my reef. Like most advanced aquarists (I hope) the pump was programmed into my controller (Apex) to try and tweak the amounts added. I will say that the pump is easy to set up, consistent in its dosing, and relatively quiet. Two major dra...Read More

REVIEW
This a is a very easy pump to setup. The pump is super quite and is perfect for the to part dosing that I am doing on my reef tank. The Pump was missing the light sensor and I called Innovative aquatics and Stan is shipping me the part right away. So very good customer service.
