The safe and energy efficient VarioS DC pump now include the new VarioS controller giving you more control. With 5 different energy saving speeds and two feed modes, the controller lets you know what your pump is doing at a glance.

Third Party Control

There is a dedicated port on the VarioS controller letting you directly connect your VarioS pump to any third party controller through a 0-10V reference port. Controlling your pump through a controller like an Apex lets you create your own flow profiles which are particularly handy for closed loop systems creating a random flow throughout the aquarium.


Having a pump that lets you directly attach a float switch has several advantages. The float can let you set high or low points in your sump, skimmer cup, or display tank that will shut the pump off when the float is activated.

The VarioS controller includes a waterproof 3-conductor union that connects to the pump creating a safe and detachable connection.
