Re: pond pump types
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.

We are not a supply web site. Just Google your filter and you should be able to find the company that made the pump and suppliers for the filters.
As far as getting it quickly, most supply places can do priority or express shipping for an extra fee.
if by large you mean one that likes the photo you have picture it is a lost cause as it it epoxy encased and unrepairable. If thats the case buy a pondmaster or atlantic pump. proven performers that are repairable and very good warranties
You can build your own little filter by placing is in a container, like yorgart, with lid, but before you do punch holes into it no more than 1/8 inch all around. the more holes the better. this way your pump does not **** something into the chamber that will stop the propeller. I have done this and it works like a charm. Also you can use pond pots, the ones that have many slits in them. Magnetic Drive Pond pumps can be left in the pond even if it froze. These pumps are great for weather. Once water unfreezes, pump will start again.
Pump Size Calculation: Gauging the correct size for your water garden pump will ensure your pond receives the proper water circulation. Unless the pump you buy is already configured with a built-in fountain head, you'll need to calculate how much a pump can handle before you choose a certain size or model. A good rule of thumb is that pumps should be able to pump out about half the pond volume every hour. So a pump that moves 500 gallons per hour would be appropriate for a 1,000 gallon pond. In order to determine the size pump you'll need, you must calculate several key measurements.
Magnetic Drive: In a magnetic-drive pump, an electrical charge creates a magnetic field that causes the magnet on the impeller to rotate and pump water. Magnetic drive pumps are completely sealed and do not require lubrication. Because they do not contain oil, magnetic drive pumps are safer for ponds with fish as oil leaks do not occur. This type of pump does not generate high head heights, meaning it is unable to lift pond water vertically, which you might need to supply water to a fountain.
Work best in cleaner environments with little or no debris Highly efficient, cost-effective operation Since they have no seals to wear out, they require little maintenance Occasionally clean the impeller and its chamber to ensure efficient operation
Direct Drive: Direct-drive pumps have an enclosed motor that is powered by electricity, which turns the impeller shaft. Direct-drive pumps achieve significant head height so they tend to work well for fountains or waterfalls. Some models seal the motor in an oil-filled shell with seals around the cord and impeller shaft. These are risky to use if you have a pond stocked with fish as there is an ever-present danger of water contamination if a leak occurs. Many newer pumps, however, feature alternative lubrication over oil that is safe for fish. Look for oil-free models if you house fish or other aquatic life in your water garden.
Typically more expensive to operate Ideal pump type for fountains or other accessories Pushes water rather than pulling it Not easily repaired by the user
Utility Pumps: Utility pumps draw water through openings that screen out debris. When placing one into a pond, use a pump sock or other enclosure to reduce the amount of cleaning needed. If you use a pump sock, be aware that sock-like screening can cause a dry pump situation.
Solids Pumps: These pumps draw water through a large opening and pump small debris through without clogging. For this reason, they can be placed into a pond without prefilters. Note, however, that this type is not safe for ponds with fish, frogs or other aquatic animals
