Reef Octopus VarioS 2 Controllable Circulation Pump
VarioS-2 Circulation Pump
The Reef Octopus VarioS 2 is a premium, controllable DC circulation/return pump for freshwater and marine aquarium applications that gives you variable speed, quiet/efficient operation, advanced features for automation, and dependable water flow. Much like other Octo VarioS pumps, the VarioS 2 features a detachable controller with mount, high-quality ceramic shaft with propeller bearing to reduce wear and tear, and the latest variable speed flow technology for refined control, enhanced performance, energy-efficiency, and safer operations.
Unlike the vast majority of circulation pumps, which use alternating current (AC), the VarioS pump boasts several key advantages over traditional AC pumps, like greater energy efficiency and safer low-voltage operation, and produces less heat per volume of flow.
>>> Now the aquarist can have full control of the water flow through their sump, reactors, filters, or closed loop systems!!!
REFINED CONTROL
In addition to allowing the pump to run at 5 different speeds, which is pretty normal for a DC pump, the new VarioS Controller takes the pump to a new level, featuring:
- A float switch connection, which allows you to connect a float switch (included in the box) to the controller. This is an added security feature that allows you to shut off your water pump when your sump water has reached a high or low level. In all, you don’t need another module or controller to add a float switch to your system.
- Two different pause/feed modes that will shut off the pump for either 15 or 60-minute intervals. These come handy when you are feeding the tank or conducting regular maintenance such as a water change.
- And the best feature of the VarioS controller is… a 0-10V input which will allow a 3rd party controller such as CoralVue HYDROS X4/WaveEngine, Neptune System’s APEX or Reef Angel to take over the pump and tell it what to do. In this mode, the new VarioS controller becomes an interface between the system controller and the pump, allowing you to create intricate programs using your system controller's native language. This is unprecedented controllability on a skimmer or water pump. In essence, you can use your system controller as your DC pump controller!
Includes: VarioS 2 pump, controller, float switch, power supply, output and input union for plumbing direct PVC, versatile stepped barb output fitting for flex tubing, and protective intake screen.
The VarioS pump has a true slow startup where the pump slowly ramps up from zero RPM to the full preset speed over a period of approximately 10 seconds.
The pump and controller are connected via a waterproof 3-conductor union. The detachable controller will allow for a simple waterproof union. The volute can rotate to change the pump's output orientation in 90 degree intervals, meaning users can output water vertically (up or down) as well as horizontally.
