Fish-farms can use water pumps all over the farm. Pond complexes also need pumps, to circulate water. To pump ponds out, top them up or return water to filters, low pressure pumps with large diameter outlets are ideal.
Pipe Pump L3
Pipe pumps are the ideal means for moving water at low pressure heads economically. They can be used for circulating water, or pumping-out ponds or tanks quickly!
Draws the water from the deeper pond zones to the surface, enriches it with oxygen and mixes it with water at the surface! This pump also mixes colder deep water and warmer surface water.
The pump component can be hung beneath the float down to a depth of 5 m. All that is required is a normal buried drain pipe of nominal 150 mm diameter. This pipe is avail able in different lengths, and can be cut according to the existing water depth. Simply attach one end of the pipe on the pump outlet, and the other to the underside of the float using the pipe clamps provided. For additional security, the pump is attached to the float by a special steel wire rope (included).
The deep pump aerator draws water from deep to the surface. The way the water is ejected at the water surface depends on the outlet type preferred, selected at the time of ordering. The simple pipe outlet gives a directional jet. As an alternative, if the conical deflector type is chosen, the result is a ‘mushroom’ shaped fountain pattern, like that produced by the Aqua-Pilz submersible.
Pumps for transporting soiled water or groundwater from ponds with maximum admixture sizes of 8-10 mm. The pumps are supplied ready for use, complete with cable, over-current device for motor protection, and Storz couplings.
In ponds and raceways, suspended solids, faecal and food wastes settle out and accumulate on the bed. These organic deposits then decompose and putrefy by natural means. The by products of this putrefaction include hydrogen sulphide. Apart from being toxic, this suppresses the appetite of fish, even when present in trace quantities. The deposits also absorb large quantities of oxygen.
