SAR Surface Aerator

The high-speed aerator line is designed to maxi-mize the two most important functions of anyaeration device-oxygen transfer and mixing ofwastewater. The waste liquid is pumpedthrough the unit in a manner which creates themost optimal spray pattern to facilitate oxygeninto the wastewater. At the same time, thispumping action creates a tank velocity patternwhich ensures the mixing of contents and thusthe oxygen dispersion. Years of experience in thedesign and application of mechanical aerationequipment, combined with the full capabilitiesof our extensive research test facility, enabled usto provide a line of high speed aerators whichnot only maximizes oxygen transfer and tankmixing characteristics but also achieving this inthe most economical and reliable way.

Construction introduction: 

Surface aerator consists of motor, driving shaft, axial-flow type impeller, and floater. The motor and impeller are coaxially connected and rotate at constant speed. The floater supports the entire body.

Motor and shaft: The electric motor is installed above the water spray range, which is TEFC type, F class insulation, 3ø, 50hz/60hz, the protection grade is IP56. The shaft is made of stainless steel.

Impeller: The impeller is made of stainless steel. The impellers are uniquely designed to achieve maximum hydraulic transmission while motor is guaranteed to be free from over-load.

Floater: The floater body is made of reinforced fiber glass, inside of which is filled with high density polyurethane (PU) foamed plastics. The mooring holes transfer tensions among the mooring cables.
