Neptune - COR-20 Intelligent Return Pump

(0) No Reviews yet


The ultimate in quiet, performance - with or without the APEX aquarium controller system - with Neptune System's COR-20 Intelligent Return pump. Features include
  • The COR is a variable speed, brushless, DC-driven centrifugal water pump designed specifically for aquariums to be intelligent, energy-efficient, unbelievably quiet, and incredibly powerful for its size.
  • The COR-20 puts out great flow while at the same time being super-stingy on power making it friendly to you wallet and the environment! Be sure to plumb the COR-20 using the largest diameter pipe possible to get the best performance. We recommend at least 1.25?
  • The COR uses the latest in Vector Control, BLDC motor technology. This drives the COR pump in a way that is both energy efficient as well as nearly vibration and noise free.
  • Snails, filter pads, or other foreign objects often find their way into a pump. Should the intake to your COR or any of your plumbing become significantly obstructed, the COR will alert you by flashing the LED on the driver. When the COR is connected to an Apex and the internet, it will send an alert to your mobile device as well.
  • The pump driver is continually monitoring the internal temperature of the COR pump motor. If it reaches an unsafe level, the driver will slow the pump down just enough to bring the temperature into an acceptable range while also providing you a notification. Some pumps shut off completely when they have a temperature issue, but the COR slows down so your tank will continue to circulate — giving you time to address the problem.
  • With a few button presses (standalone mode) or some simple configuration in Apex Fusion, you can set a Feed Mode that will slow the pump to any level you choose. When connected to an Apex, you can even have other tank operations sequence with this feed mode and the time interval of the Feed Mode can be customized as well. When connected to an Apex, the buttons on the COR driver also function as an easy to use feed button.
  • The COR comes complete with all the fittings necessary for most aquarium configurations (0.75? output, 1.0? input). But we’ve also included a 1.25” union for the output so you can connect the pump in a manner that will result in the least amount of head loss. Plumb your main return-line in 1.25? and get the full potential of the COR pump – as much as 50% or more flow!
