In hydraulic engineering, agricultural irrigation, and municipal drainage, certain scenarios require more head pressure than standard axial flow pumps can provide, yet still require a higher flow rate than typical centrifugal pumps. Kairun Pump’s submersible mixed flow pumps bridge this gap. Utilizing a diagonal flow path where fluid is pushed both axially and radially, these pumps deliver a balanced combination of medium head and high capacity. By combining the motor and pump end into a single submersible unit, they operate directly underwater, minimizing land footprint and simplifying structural installations.
Our submersible mixed flow pumps are utilized in various water diversion and infrastructure projects:
Large-Scale Agricultural Irrigation: Transporting river or reservoir water across long distances to irrigation channels with moderate elevation changes.
Municipal Drainage & Stormwater Management: Removing urban runoff and drainage water from low-lying areas during heavy rain events.
Industrial Cooling & Circulation: Supplying high-volume cooling water to thermal power plants, steel mills, and chemical facilities.
Water Treatment Intake: Moving raw water from intake wells into municipal treatment plants with stable flow regulation.
Robust Hydraulic Performance: Specially designed mixed flow impellers optimize the diagonal flow angle, ensuring smooth flow transitions and stable efficiency.
Heavy-Duty Motor Engineering: Equipped with IP68 submersible motors featuring Class F insulation, high-grade silicon steel laminations, and double mechanical seals to prevent moisture ingress.
Advanced Protective Monitoring: Optional thermal switches in the stator windings and leakage sensors in the oil chamber detect operating abnormalities, preventing motor burnouts.
A: You should select a mixed flow pump when your system's total dynamic head (TDH) exceeds the efficient range of axial flow pumps (typically above 8 to 10 meters) but still requires a high volume of water. Mixed flow pumps comfortably handle heads up to 20 meters or more in single-stage designs.
A: Our mixed flow pumps support several standard installation methods, including steel well-tube installation, concrete well-pit installation, and sliding-rail coupling systems. Our technical department can assist with layout planning and custom well sizing.
A: Yes, our mixed flow pumps are designed with wide fluid passages that can handle raw river water containing minor sediment or small suspended organic debris. For larger solids or trash, we recommend installing our PG/PW static flat screens or trash racks at the intake to protect the impeller.
