The new Gigaflow DC pumps from Rio might have a familiar body and style but the underlying technology of these pumps is fundamentally different. Rio will be making the new Gigaflow pumps in 8 different sizes, most of which are controllable, but all of which use a DC motor to improve the overall performance of the pump.
Rio pumps have been a mainstay of the fresh and saltwater aquarium hobby for the better part of two decades, and all that time it’s been the same old AC motor with all its inefficiencies and let’s just say, checkered performance and reliability history. With the new DC pump technology in the Gigaflow, Rio has created a new class of water pumps in their expansive catalog, and let’s just say these pumps can push serious volume.
The eight sizes of Rio Gigaflow will range the spectrum of aquarium pump sizes. The 42 watt GF-4000 which pushes a maximum of 4,000 liters per hour with a maximum head of 3 meters in a body not too different from Rio Hyperflow.
Meanwhile the honking Gigaflow GF-16,000 quadruples that max flow rate while using 185 watts and having a max head pressure of 4.5 meters. Most of the Rio Gigaflow pumps will be speed adjustable in about ten different increments but there will also be two A-series Gigaflow pumps which will have a fixed output.
