VERY IMPORTANT!
One pump per controller
It is not possible to connect 2 pumps to one controller.
Incompatibility with Gyre series pumps
Jump series pumps and controllers are not compatible with Gyre series pumps and controllers and vice versa.
Incompatibility with Gyre series spare parts.
Jump series spare parts are not compatible with Gyre series spare parts and vice versa.
Explanation of cross-flow technology
Compared to conventional flow pumps and wavemakers based on propeller nozzle technology, our latest Gyre flow pump is based on cross-flow technology.
propeller nozzle technology
(Propeller Nozzle Technology)
① Dead zones with relatively poor water movement.
② Very strong current in the middle, this makes the placement of corals difficult.
③ Very weak current at the other end of the aquarium.
cross-flow technology
(Cross Flow Technology)
① Virtually no dead corners.
② Evenly distributed flow throughout the aquarium.
③ The water hits the other side of the aquarium to create a complete circuit, i.e. the creation of a « gyre flow ».
Almost silent operation thanks to sine wave technology
sine wave diagram
When using sine wave technology, the current flows in much flatter waves.
decibel levels with sine wave technology
Conventional diagram
With conventional technology, the electrical current changes more.
