Neptune COR-20 Intelligent Return Pump (2000 GPH)

Neptune COR-20 Intelligent Return Pump (2000 GPH)

The Neptune COR-20 Intelligent Return Pump (2000 GPH) is an energy-efficient aquarium return pump for circulating water in reef and saltwater systems. It runs on its own out of the box, or connects to an Apex controller through an Aquabus port for advanced control, monitoring and feed-mode settings.

Key Benefits

• Works with or without an Apex controller. Standalone operation is fully supported, and the driver controller gives simple speed control up and down as you like.
• IQ-Level technology lets you set minimum and maximum speeds to suit your tank's plumbing, plus a minimum flow rate for in-tank flow and feed modes.
• Moves up to 2000 GPH with an efficient head-loss curve.
• Quiet, vibration-free running from Vector Control BLDC motor technology.
• Energy efficient, drawing less than 50W at full power.
• Temperature monitoring and operational feedback help you spot problems before the pump fails.
• Aquabus communication connection for direct integration with any Apex controller.
• Can be used internally or externally.

Standalone or With Apex

No Apex? No problem. The COR-20 is capable of stand-alone operation, with the driver controller giving you simple control over pump speed. Connecting it to an Apex controller unlocks much more. The COR range was built from the ground up with control in mind, so Apex Fusion Cloud Software (Apex required) lets you manage the output percentage, view real-time operational feedback, and monitor and control pump status and feed routines.

How to Use

• Plug the pump into an open Aquabus port on your Apex controller using the Aquabus cable.
• With a couple of button presses, set the pump's flow rate and feed mode settings.
• Enable IQ-Level to set the minimum and maximum flow rates for your aquarium.
• Choose an output fitting to match your tank's existing plumbing. The largest 1.25" union is suggested, but the 0.75" or 1.0" adapters are fine if needed.

Operational Feedback and Protection

Saltwater aquariums are notorious for calcium and other mineral build-up on pumps and their internal parts. This can restrict flow and, more importantly, damage the pump. With Apex Fusion you can monitor the pump's internal temperature, wattage draw and flow rate, and set alarms and alerts if any reading moves outside its normal threshold. If the pump temperature rises to unsafe levels, the COR slows itself down until it is back to a safe temperature, giving you time to react and maintain the pump.

Suitable For

• Reef and saltwater aquariums that need a quiet, controllable return pump.
• Hobbyists who want standalone running now and the option to add Apex control later.
• Aquarists who want to monitor pump health, flow and power draw.

Compatibility

• Compatible with any Apex controller (requires an Aquabus port).
• Some features require an Apex controller system.
• Output options suit 0.75", 1.0" and 1.25" plumbing sizes.

Frequently Asked Questions

Do I need an Apex controller to run the COR-20?
No. The pump can run stand-alone, with simple speed control from the driver controller. An Apex controller via an Aquabus port adds the advanced control features, and Apex Fusion Cloud Software is needed for the monitoring and alerts.

Which output fitting should I use?
The largest 1.25" union is suggested. The 1.0" and 0.75" adapters are also supplied and are fine if your plumbing needs them.

How much power does it use?
It uses less than 50W at full power, thanks to its Vector Control BLDC motor. The specification lists power consumption as less than 90W @ 120VAC.

What happens if the pump gets too hot?
The COR slows itself down until its temperature returns to a safe level. With Apex Fusion you can also set alarms and alerts on temperature, wattage and flow rate.

Can it be used inside or outside the tank?
Yes, the pump is listed as suitable for internal or external use.

The specification mentions 120VAC. Should I check anything before installing in South Africa?
The listed power figure is @ 120VAC. Before connecting the supplied 100W DC power supply to your local mains, confirm that its input rating suits your supply.
