OCTO VarioS 10 Pressure-Rated DC Return Pump
OCTO VarioS 10 — Return flow for demanding plumbing
The pressure-rated VarioS 10 is built for higher-head installations and demanding return circuits. Suitable for marine and freshwater use, with submerged or external installation following the supplied instructions.
François Neo’s recommendation
I choose a return pump by the flow it can deliver through the actual installation. Include lift height, pipe diameter, bends and manifold outlets in the calculation, then check the pump curve. Keep sump turnover separate from the circulation your corals need inside the display.

Check the required interface cable and controller compatibility before planning an automated installation.
What comes with the pump
Pump, controller, power supply, mounting hardware and plumbing connections. The manufacturer lists the float switch as a separate accessory; package contents should be confirmed before ordering.
Installation considerations
Use the VarioS 10 performance curve to assess higher lift heights and restrictive plumbing. Its pressure rating does not guarantee the required flow for every installation. Allow room for fittings, removal and impeller cleaning. Keep the controller and power supply dry, and test both drain-down and restart after installation.
