What kind of filtration will the pump be used for? A wet/dry filter? A sump with submerged media? Some type of canister filter without its own pump? A pump for a UV sterilizer? A pump for a closed loop system? How much head? Do you want a submersible pump or an external pump? Different types of filtration have different turnover rates.
That said, if you are looking for an external pump, check out Reeflos. A Barracuda Gold pump would probably work. If the flow rate is too high, the flow rate can be reduced by necking down the return pipes, and/or gate valves. There's a whole line up of external Reeflo pumps, and I'm sure there is a pump that would work for you. You can easily select the right pump based on what turnover rate you want to achieve.
