Floating Extractors

The floating ball makes sure that the suction basket of the floating pump intake is situated always aprox. 15 – 20 cm below the water surface. Thus no surface water can be sucked in, which is polluted often with a residue of grease and flour. Below the sedimentaion is advanced at most. Thus the pump sucks the cleanest water in the tank.



A floating filter is among the most important elements of a rainwater collection system. The purpose of a floating filter is to ensure that the pump is always extracting the highest quality water from the tank. The floating ball suspends the extraction filter just a few inches below the surface of the water where the highest oxygen content exists and well above the fine anaerobic sediment layer at the bottom of the tank. The screened extraction filter adds an additional layer of protection for the pump and demand-side systems by filtering out any particles larger than the openings in the screen mesh. The floating ball has an eyelet at the top which is used to secure the extractor above the sediment layer using the supplied 1/8” braided nylon rope. The extraction filter is available in various mesh sizes but most commonly in “Coarse” and “Fine” sizes. Coarse typically ranges approximately 1200 microns while the Fine mesh typically ranges about 300 microns. The most common floating filters are the Coarse mesh because of their inherent ability to remain open to the flow of water. Fine mesh filters typically require more frequent maintenance and cleaning and the substrate can become clogged, adversely affecting the flow of the pump intake.  We distribute 1″, 1 1/4″, 1 1/2″, 2″, and 3″ floating extractors.
