SAR Surface Aerator

Details

The high speed aerator line is designed to maximize the two most important functions of any aeration device-oxygen transfer and mixing of waste. The waste liquid is pumped through the unit in a manner which creates the most advantageous spray pattern for introducing oxygen into the liquid. At the same time, the pumping action creates a tank velocity pattern which insures the mixing of contents and thus the oxygen dispersion. Years of experience in the design and application of mechanical aeration equipment have been combined with the full capabilities of our extensive research test facility to provide a line of high sped aerators which not only maximize oxygen transfer and tank mixing characteristics but perform these functions in the most economical and reliable manner.

APPLICATION

For sewage, agricultural and pastoral farming and other types of industrial sewage aeration. SAR device pumps water from the bottom to the top and creates circulation flow and stir processes to create the spray pattern/water drop through the water panel. When water contacts air, it will become water drops, which fall to water surface and form the turbulence and bubbles. These bubbles will improve oxygen dispersion and increase oxygen in water.

CONSTRUCTION:

* All wetted metal parts shall be of corrosion resistant materials, and shall not require painting.

1. MOTOR AND SHAFT
   • The electric power unit is the heart of the machine, and is located above the high-density spray-diffusion zone to minimize its exposure to the nature and contents of the pumped liquid. The motors are Weatherproof Chemical Service, TEFC (Totally Enclosed Fan Cooled) 3phase. These motors utilize a highly refined non-hygroscopic class B insulation system, in additional to which motor housing drains are provided to drain off internal condensation. Shaft is one piece from the upper bearing through the impeller.
2. IMPELLER
   • The impeller is constructed of stainless steel and is manufactured using the machined-pitch process which assures perfect impeller accuracy and top performance. The impeller pitch is designed for maximum hydraulic delivery without overloading the motor.
3. FLOATION ASSEMBLY
   • The floatation hull is constructed of reinforced fibre-glass. The hull is completely filled with high-density closed cell polyurethane foam. The mooring eyes transfer tension from one mooring cable to another.
