The TetraPond Debris Handling Pump provides clog-free performance for power filters and waterfalls. This energy efficient pump is engineered for continuous operation and can handle debris up to ¼ inch in size—allowing you to clean your pond, not your pump! Max Flow Max Pumping Height Pond Size DHP 3600 3690 GPH 11.4 Feet Up to 3000 Gallons DHP 4200 4235 GPH 13.1 Feet Up to 4000 Gallons
How It Works
TetraPond DHP pumps are engineered to circulate large volumes of pond water without clogging. This allows the pump to operate for long periods of time without any maintenance. Water, dirt, and debris are drawn through the quarter inch holes in the large pre-filter cage that surrounds the pump. The pre-filter cage prevents leaves, sticks, and other large debris from entering the pump. It also protects the fish from the pump’s impeller. The open-face impeller allows debris up to 1/4 in. in diameter to pass through the pump without clogging. The pond water with dirt and debris are pumped to an external filter for removal or directly to a waterfall or stream.
Determine how high you waterfall will be from the pond surface. The higher the top of the waterfall is from the pond surfaces, the less flow will result. Take a look at the charts below for the approximate waterfall effect the DHP pumps will create at various pumping heights.

Pond Circulation: Choose a pump that will circulate 100% of the pond volume in one or two hours. More circulation will result in better pond conditions.
Filters: Be aware that filters reduce the flow to waterfalls and streams. The image on the left shows water pumped at three feet without any filter restriction, while pumping at three feet with a TetraPond pressure filter reduces flow by about 45%.
