Water Circulators

"We use many Kasco units with the Universal Dock Mount option in the summer for water quality purposes. They keep organic material and debris from floating into our marina. They have been effective and dependable."

Water Circulator


F3400/CF Water Circulator

Circulator used in a pond to eliminate stagnant water.

Kasco Water Circulators are truly year round equipment. Water Circulators can be used in the Summer months to mix and agitate stagnant water to help reduce aquatic plant growth and inhibit mosquito reproduction. In Spring and Fall, the Water Circulators can help destratify deeper bodies of water to help prevent or limit the negative effects of pond turnover. Finally, in the winter months, Water Circulators can be used to keep areas of water open to help prevent winter-kill on fish populations and protect permanent fixtures in your pond such as docks.

Kasco Water Circulators are perfect for creating directional flow in your pond or lake. Creating the directional flow will turn your still, stagnant water into a stream environment and help add vital oxygen and improve your pond or lake aeration. Still, stagnant water is ideal for the growth of unwanted surface and bottom vegetation such as algae. By eliminating the stagnant water, the water circulators may help limit the growth of the unwanted aquatic plants and keep your pond cleaner. Still, stagnant water is also ideal for mosquito reproduction, including those that may carry the West Nile Virus. Creating the stream environment may also help limit the reproduction of mosquitoes and the overall population of mosquitoes in your area. Also, in Summer months, Kasco Water Circulators can be used to keep floating debris out of bays, marinas, and canals, as well as, around docks and beaches.

Click on the picture below to see a slide show of a test performed a Southern Illinois University on October 6, 2004. A Kasco F2400CF, 1/2hp Water Circulator model was placed in a 102' x 42' x 7' pond containing roughly 225,000 gallons of water with about 1/5 gallon of Aquashade pond dye added to see the mixing results. The pictures were taken every 30 seconds. Watch how fast only a 1/2hp Kasco Water Circulator can thoroughly mix this pond.

Circulator used for waterfowl hunting

Circulators can be used to extend Waterfowl hunting with more open water.

Kasco Water Circulators have been used with great success for waterfowl hunting as well. Many waterfowl hunting seasons are cut short due to cold weather and freezing water. However, a Kasco Water Circulator can be used to keep the water open and extend your season and attract birds to your location. Since most hunting blinds do not include electricity, most hunters who use Kasco Water Circulators will operate the unit with a generator before sunlight to open the area. Then before shooting hours, will turn the generator off to avoid spooking the ducks and geese.

Kasco Water Circulators are great tools to limit the negative effects of Spring and Fall turnover. Ponds in geographic areas that see large temperature swings between Winter and Summer often have Spring and Fall turnover. Spring and Fall turnover occurs when deep, stratified (large temperature differential between surface and bottom water separated by a thin layer of water called a Thermocline) water "turns over". In Spring, the surface water is heated by the sun to about 39 degrees and becomes more dense than the colder, de-oxygenated bottom water. When the warm surface water becomes too dense for the colder water to support, the pond water will turn over and have the colder water on the surface. This causes the de-oxygenated water to mix with the oxygenated surface water and cause an overall lower oxygen level. When large numbers of fish are present, oxygen levels can become low enough for a fish die off to occur. In Fall, the exact opposite occurs. The surface water is cooled by cooler nighttime periods and when the surface water is around 50 degrees, the pond again turns over. Kasco Water Circulators can be angled downward to destratify ponds to about 18' in depth. By destratifying the water, Kasco Water Circulators move cooler de-oxygenated water from the bottom to the surface where the water can be warmed and oxygen diffused through the air-water interface causing the elimination of the thermocline and large temperature differential and increasing oxygen levels throughout the entire water column and improve your lake or pond aeration.

Circulator used for Ice Prevention in Northern Wisconsin

Circulator used for winter kill prevention and to protect docks from ice damage.

Kasco Water Circulators can be used to help prevent winter-kill conditions and protect permanent fixtures in your pond or lake. During harsh winters with thick ice and heavy snow pack, your pond can experience a fish die off due to low oxygen levels. The heavy snow and ice prevent sunlight from penetrating into the water causing the existing aquatic vegetation to die off. As the vegetation dies, the decomposition process uses up much of the available oxygen in the pond. As the winter progresses, the oxygen levels continue to decrease and eventually, your fish may begin to die. A Kasco Water Circulator will mix the water and move warmer, bottom water to the surface to keep an area of the pond open. Only 1% of the ponds total surface area needs to be ice free to prevent winter-kill situations. The cold water will become oxygenated by coming in contact with the air and prevent winter-kill on your pond. Also, Kasco Water Circulators positioned around docks and/or boats can prevent costly ice damage by keeping an area ice free around your valuables. Depending on your situation, the Kasco Water Circulators can mounted in three different methods; Rope Suspension, Universal Dock Mount, and Horizontal Flotation Unit (comes with Circulator).

Installation Options for the Circulator Models

ROPE SUSPENSION : The Water Circulator can be mounted in either a vertical or angled position with ropes or cables.

UNIVERSAL DOCK MOUNT: Kasco also offers an optional dock mount, which allows for either vertical or several angled positions.

FLOTATION KIT: Kasco Water Circulators can be suspended from the flotation kit to create elongated patterns of water movement. The unit rests less than two feet below the surface and is ideal for shallow water or where there is no dock or place to suspend the unit. With 5 angled positioning options, the flotation kit allows for easy adaptability for most situations.

Kasco Water Circulator models include the following staples of all Kasco Fountains, Pond Aerators, or Water Circulators:

  • Longer-life top and bottom ball bearings
  • Environmentally friendly oil-filled motor with a hard-face internal mechanical seal and external lip seal for protection against leaks.
  • Flood oil lubricated for excellent heat dissipation.
  • Highly efficient, lower power consumption than competitive equipment
  • Superior dependability in salt-water or other corrosive environments. All external metal motor, float, and hardware components are of stainless steel composition and protected by a sacrificial zinc anode.
  • Requires minimal maintenance. We recommend cleaning the stainless steel motor housing once or twice per year and replacing the sacrificial zinc anode when visibly corroded.
  • ETL listed to stringent UL and CSA Safety Standards
  • U.P.S. Shippable
  • Made with pride in the U.S.A.

Kasco Water Circulators are available in the following models. All include a horizontal flotation kit and two 50' braided nylon mooring ropes and are available with 50', 100', 150', or 200' SJTOW underwater rated electrical power cords.
