Yes there are many water pumps with an adjustable flow rate (GPH) if you want to relocate the water pump in different aquariums. You should visit http://www.allpondsolutions.co.uk and look under adjustable water pumps.
This is a lot of pump for a fish pond. You should use the safe-guards as you would find in a pool, two drain's separated by 3 or so feet and/or a couple skimmers. You dont want the fish getting pulled into the drains/skimmers. It will also be a lot of $ to run the pump compared to a smaller 'fish pond' pump ... of course your pond may be much larger than the average garden variety.
Personally, I dont think this is a good idea for a small pond. Tell me more about your pond.
There are basically two types of pond pumps to choose from - externally mounted and submersible.
External pumps were traditionally used in water gardens. They sit outside the pond, with a hose that leads from a strainer in the pond to the pump. From there the water is forced either to a waterfall, stream or fountain.
Because external pond pumps are often noisy and require extra plumbing, they are usually not suited for most backyard ponds. Due to easier accessibility and ease of repair, however, external water pumps are often the best choice for larger water gardens and public installations.
Submersible water pumps are usually preferred by most do-it-yourselfers. They sit underwater where they are quiet and unseen. These pumps are easy to install, require no priming and stay cool thanks to the surrounding water.
Submersible pumps draw water from the bottom of the pond, either through a strainer or biological filter. A hose attached to the outlet then feeds water to whichever water feature you have installed.
