Sedra pumps are powerful, quiet and reliable. When combined with a needlewheel impeller, they become ideal for use in protein skimming. The pumps incorporate a venturi intake, sucking both water and air into the impeller. The many needles on the impeller wheel shred up the air and water into very fine micro bubbles and sends them into the skimmer contact chamber.

 

These impellers are made with a ceramic shaft and a molded needlewheel impeller plate. With it's many needles, the impeller shreds the incoming mix of air and water into a combination of water and extremely fine air bubbles. These fine bubbles are injected into the protein skimmers reaction chamber where dissolved organic molecules bond to the surface of the bubbles which are then exported into the collection cup.
