Ultimate wastewater treatment equipment designs.

Specifically designed for optimum efficacy, the EcoJet™ aerator design meets the most demanding operational requirements. The high-speed aerator provides ultimate versatility with modular units that can easily be added, repositioned or upgraded, allowing for greater adaptability and flexibility to maintain efficiencies throughout changing conditions.

Major features and components.

1. Proprietary Motor

  • Totally enclosed motor, fan-cooled
  • Heavy gauge cast iron fan shield
  • Class F insulation
  • Service factor of 1.15, optionally up 1.25
  • Standard or premium efficient available
  • Double-row bearings on drive end
  • Heavy-duty L-10, 100,000-hour bearings
  • Dynamically balanced and vibration tested
  • Designed to meet the most demanding operational requirements

2. Motor Junction Box

  • Opening in motor housing for winding leads is completely potted with epoxy filler

3. Motor Shaft

  • One-piece continuous shaft from upper bearings to the propeller
  • 17-4 PH stainless steel in the 1150°F heat-treated condition
  • 135,000 PSI minimum yield strength, 35 % stronger than competition
  • Largest diameter shaft
  • Threaded and keyed on drive end for simple propeller installation

4. Labyrinth Seal Guard

  • Positioned below the bottom motor bearing to prevent moisture from migrating up the shaft into the lower bearing

5. Discharge Cone

  • Massive monolithic casting, heavier than competition
  • Large integral webs for rigid stability and increased lateral strength
  • Designed for minimum head loss
  • 304 stainless steel or cast steel epoxy-coated
  • Provides for lowest vibration levels
  • Produces maximum diffusion of water particles
  • 100% contact with the volute, which distributes both static and dynamic loads

6. Deflector Bearing

  • Shaft runs free under normal operating conditions
  • Provides support only when under load

7. Float

  • Largest one-piece float available
  • Engineered to provide stability and better buoyancy
  • Fiberglass reinforced polyester (FRP), or
  • 14-gauge, 304L or 316L stainless steel
  • Filled with closed-cell polyurethane foam that adds structural stability and prevents the possibility of sinking if damage occurs to the float exterior

8. Debris Deflector

  • Machined for smooth fluid passage over the surface
  • Material: Delrin® – An Industry-Leading, High-Performance Acetal Resin made by DuPont™
  • Attached with three recessed, stainless steel set screws
  • Double engagement provides an extra measure of preventing water migration up the shaft

9. Propeller and Key

  • Maintenance friendly propeller exchange with keyed design and threaded shaft
  • Keyed to mate to motor shaft in proper position
  • Secured to shaft by stainless steel locking nut
  • Precision investment casting
  • 316L or 15-5 stainless steel
  • Dynamically balanced
  • Anti-fouling, non-cavitating for greater operational efficiency

10. Locking Nut

  • Stainless steel
  • Firmly and securely locks the propeller to the shaft
  • Just two tools required to install or remove the propeller 11 Volute
  • 304L or 316L stainless steel
  • All sizes have bottom flange for simple bolt-on attachment of the standard intake cone or optional antierosion assembly or draft tube
  • Gussets at top and bottom flanges add strength

11. Volute

  • 304L/316L stainless steel
  • All sizes have bottom flange for simple bolt-on attachment of the standard intake cone or optional antierosion assembly or draft tube
  • Gussets at top and bottom flanges add strength

12. Intake Cone

  • 304L stainless steel
  • Hydraulically designed for proper loading on propeller
  • Sufficiently sturdy to support assembled aerator on hard, flat surface
  • (Optional) Draft Tube for deep water depth application

13. Anti erosion Assembly

  • (Optional) for low-water depth application
