Features
- To increase OTR(Oxygen Transfer Rate), and reduce Biochemical oxygen demand(BOD) from wastewater treatment.
- Mixing and stirring applications result in uniform Mixed Liquor Suspended Solid(MLSS) due to fine bubbles convention.
- Dry motor with overload protector; Cable with an epoxy resin sealed water-proof cable hood; Use deep groove C3 bearing to extend life time.
- Superior abrasion resistant dual mechanical seals made of SIC material to ensure best seal effect and reduce abrasion from sewage.

- EFJ is suitable for wastewater containing solid particles.The solid passage of EFJ ejector pump is 35~50mm.
- EAJ is customized, and it's suitable for sump or wastewater containing tiny solid particles.The solid passage of EAJ ejector pump is only 6mm.
- Please place the EFJ/EAJ on concrete or a hard surface in the Wastewater Pond. Never sink EFJ/EAJ in mud.
Applications
- Oxygen aeration of wastewater for wastewater treatment.
- Oxygenated for aquaculture, such as fishing farming or shrimp farming or hydroponics applications.
