Development and Manufacturing of Submersible Sewage Mixers at Berkeh Ab Afzar Pump Manufacturing Company
In line with the development of its industrial products and in response to the needs of the country’s water and wastewater industries, Berkeh Ab Afzar Pump Manufacturing Company has been engaged in the design and production of submersible sewage mixers since 2020. Relying on engineering expertise, domestic manufacturing capability, and modern computational fluid dynamics (CFD) analysis methods, the company has successfully designed and manufactured new models of these devices in recent years.
The mixers produced by the company are available in the power range of 2.2 to 15 kW, with all design parameters — including propeller diameter, rotational speed, and installation angle — determined based on hydraulic calculations and the mixing conditions of the basin or tank to ensure complete and uniform fluid mixing.
These mixers are equipped with high-efficiency planetary gearboxes, which ensure reliable torque transmission, smooth operation, and minimal maintenance requirements.
With optimized hydrodynamic design, low energy consumption, and customizability according to process conditions, Berkeh Ab Afzar submersible mixers are a dependable choice for use in municipal and industrial wastewater treatment plants, aeration tanks, and mixing systems in various industries.
Berkeh Ab Afzar Pump Manufacturing Company continues to move forward in improving quality, increasing efficiency, and expanding the power range of its equipment to meet the growing demand of the country’s industry for advanced and locally manufactured technologies.
