Selecting pond pumps can be confusing but it is critical that the proper pump is chosen to ensure longevity and trouble free performance Following are several things to keep in mind when selecting a pond pump.

How much volume do you need?

It takes approximately 36 gallons per minute to make a waterfall 1” wide x 1” deep (1” deep water is considered an average depth for resedintal applications). The first step in determining how much water you need is to multiply the width of the waterfall in feet x 36 = gallons per minute needed to make 1’’ thick water over your falls. This will determine your water volume.

This determines how much volume you need

Next, determine how much head(lift) there is from the surface of the pond to the top of the waterfall. On a small, simple waterfall the vertical lift is all you need, however on large applications you also need to factor in friction loss from the pipe as well as each fitting to the total head.

This determines head pressure

Now that we know water volume needed and the head height it is needed at, it makes selecting a pump much easier. You will find the head pressure in the description of each pump.

In addition to the pond pumps shown we have many additional pond pumps available. We specialize in high volume pumps and can supply you with virtually any size pond pump you could ever need.

Submersible Pond Pumps - Our Submersible Pond Pumps are suited for small ponds starting at 200 gallons to larger ponds over 2000 gallons. Our larger submersible pumps are ideal for high volume water falls.  Flow rates range from 120 GPH to as high as 24,000 GPH for a larger waterfall pump. Typically, the ideal pump will circulate the total volume of the pond at least once per hour.  For example, if you pond is 500 gallons, you would want to go with at least a 500 GPH pump.

External Pond Pumps are ideal for medium to larger pond sizes. For example: a pond that consitst of 1000 gallons of water or more is a good candidate for one. This type of pond pump is especially effective for larger ponds because it is energy efficient. The cost of using a submersible pump in a large pond can be much higher. Also, external pumps can handle larger water flows. And an even further benefit of this type of pump for a large pond is that it works well with biological filters.

Mag Drive Pond Pump is a type of sealless pump that utilizes a magnetic coupling to create a static shaft seal.  Magnetic force aligns the outer magnet (drive magnet) and inner magnet (driven magnet) through a stationary containment shell (canister).  This eliminates the hazards and mess caused by packing or mechanical seal failure. These sturdy pond pumps are ideal for watergardens and ponds, statuary and hydroponic gardening, or wherever you want to pump salt or freshwater efficiently.
