How we ranked these
We ranked the pumps on the maximum flow each maker states, highest first. All ten are centrifugal pumps that the maker says can run submerged or in the water, so we compared return and utility pumps with each other and left out powerheads and wavemakers, whose flow is quoted differently. Danner quotes flow in GPH only, so it is placed first on its stated 3,060 GPH against the 2,900 US gal./h Tunze states for the Silence Pro; the rest are ordered by the l/h or liters per hour their makers state. Power, head and price are shown where the maker page states them, and prices are shown only where a page publishes one. Every figure is a maker claim read from the maker page; we cite no independent test. Several pumps from an earlier shortlist were replaced because their official pages could not be read or the product was not a submersible pump: the two Fluval pumps (the Fluval site blocked automated reading), the two Jebao pumps (no readable official spec page), the AquaClear and Hydor Koralia powerheads (powerheads with no readable official page), and the AquaMaxx HOB-1 (a hang-on-back filter, not a pump). Facts are taken from each maker's own published information; check the official site before you buy.
Questions people ask
Which pump here has the highest stated flow?
The Danner Supreme Aqua-Mag 3600 comes first on its stated 3,060 GPH at 1 ft of head, just above the 2,900 US gal./h Tunze states for the Silence Pro. Danner states flow in GPH only, so it is not in the l/h chart.
Can these pumps run in the water?
Each maker says so in its own words. Danner says its pumps operate submerged or in-line, Sicce lists a WET & DRY application, EHEIM says its universal pumps can be used in/under water or outside the water, Aquael says its UNI PUMP can operate fully submerged or externally, and JBL says the ProFlow t500 is completely submersible (IPX8).
Are the flow figures what I will get in my tank?
Not necessarily. Every figure is a maximum the maker states. Danner, for example, lists 3,060 GPH at 1 ft of head and a lower flow at greater heights, with a shutoff at 22 ft 6 in.
Does Tunze say its Silence pump output can be adjusted?
Yes. Tunze lists the Recirculation Pump Silence 1073.060 with adjustable output and a pump output of 2,500 to 5,000 l/h.
