Overview
The Vectra S2 is the smallest pump in EcoTech Marine's DC lineup — 5,300 lph flat out, 3.5 m of head pressure, and everything in between available on a dial or from your phone. It fixes the classic small-system problem: an AC pump that's either too much or not enough, choked back with a gate valve that wastes power and adds heat for no good reason.
Like the rest of the second-generation Vectras, the S2 gets revised input and output couplers designed around standard PVC, a new base, a tougher motor sleeve, improved thermal management and more ergonomic collars. Quiet, controllable, and small enough to fit in a sump that isn't the size of a bathtub.
Key features
- Fully adjustable DC flow — up to 5,300 lph, dialled down to suit your overflow without a restricting valve and without wasting electricity.
- Mobius app included — wireless is built in, and the free Mobius app (iOS and Android) handles schedules, mode changes, status updates and firmware.
- Auto-calibration — the S2 can calibrate itself to your system, which prevents back-siphoning if the pump is turned down and gives a proper neutral flow condition in Feed Mode.
- Feed Mode and Speed Lock — pause flow at the touch of a button while you feed, then lock the dial so your settings stay where you put them.
- Closed-loop modes on board — Lagoonal Random, Reef Crest Random and Gyre are all available if you run the S2 as a closed loop instead of a return.
- QuickCouple fittings and a rotating volute — rotate the outlet to suit your plumbing, and lift the pump out for a clean without cutting pipe.
- British Standard Pipe threading — plays nicely with Australian plumbing supplies.
- Battery Backup compatible — the EcoTech Battery Backup keeps water moving through an outage. For return pump duty you'll also want the Vectra Battery Backup Booster.
- ReefLink and EcoSmart compatible — sits alongside VorTech pumps and Radion lighting in the wider EcoTech ecosystem.

Who it's for
The S2 suits nano and mid-sized sumped reefs — think an all-in-one with a sump conversion, a three or four foot display, or a frag system where a small footprint matters. The 98 x 165 mm base is genuinely compact, which counts for a lot when your sump also has to house a skimmer and a media reactor.
Take note of the head pressure, though: at 3.5 m the S2 has less lift in reserve than its bigger siblings. If your return has to climb a tall stand, feed a manifold, or run a long horizontal stretch with several elbows, step up to the M2 rather than asking the S2 to work at the top of its curve all day.
Setup & tips
- Do the head-loss maths before you buy. Vertical rise plus fittings eats into that 3.5 m quickly — count your elbows honestly and leave yourself margin.
- Run auto-calibration once the plumbing is finished. It's what makes Feed Mode behave and it's your protection against back-siphoning at reduced speed.
- Keep the intake side generous. The inlet is 25 mm and the outlet 19 mm — restriction before the pump costs you far more than anything after it.
- Set Speed Lock once you're dialled in. Find your turnover, lock the dial, and the sump stays where it should even if curious fingers find the controller.
