VarioS-4 Circulation Pump

The Reef Octopus VarioS 4 Circulation Pump 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 producing 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 standard for a DC pump, the new VarioS Controller takes the pump to a new level featuring:

 

  1. A float switch connection, which allows you to connect a float switch (included in the box) to the controller. This added security feature will enable 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.
  2. Two different pause/feed modes 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.
  3. And the best feature of the VarioS controller is… a 0-10v input which will allow a 3rd party controller such as 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 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 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.

Compare VarioS DC return pumps

Model Max flow Max head Power Voltage
VarioS-2 792 GPH 13 ft 25 W 24 V DC
VarioS-4 (this page) 1,050 GPH 14.7 ft 40 W 24 V DC
VarioS-6 1,720 GPH 16 ft 70 W 36 V DC
VarioS-8 2,700 GPH 18 ft 98 W 36 V DC

Size a return pump on the flow you get after head loss, not the maximum rating. Need more than 2,700 GPH? See the VarioS-10 (4,220 GPH). Every VarioS return pump has 5 speeds, an included float switch, 15 or 60-minute feed modes and a 0-10V input. VarioS pumps are not pressure-rated, so don't use them floor-to-floor or to feed Beckett or downdraft skimmers.

Not to be confused with: the VarioS-4S, a pinwheel skimmer pump used on Regal 200 skimmers. The VarioS-4 is a water (return) pump, and the two are not interchangeable.

VarioS-4 Controllable DC Pump (1050 GPH) FAQs

What are the VarioS-4 max flow and head height?

The VarioS-4 moves up to 1,050 GPH with a maximum head height of 14.7 ft. It draws 40 W at 24 V DC.

What plumbing size does the VarioS-4 use?

The input is a 1.25" male union thread. The output takes 32 mm / 1" slip PVC or a 3/4" barb, and the pump includes input and output unions, a stepped barb fitting and an intake screen.

Does the VarioS-4 have a feed mode and float switch?

Yes. Two feed modes pause the pump for 15 or 60 minutes, and the included float switch can shut the pump off when sump water reaches a high or low level.

How do I choose the right size return pump for my reef tank?

Work from the flow you get after head loss, not the maximum rating. A common starting point is about 3 to 5 times your display volume per hour through the sump. If the VarioS-4 falls short at your head height, step up to the VarioS-6 (1,720 GPH).
