Submersible sewage pump

Transform your water treatment and mixing processes with our advanced submersible mixers, designed for seamless integration and relentless reliability. Featuring a robust dual mechanical seal, stainless-steel construction, and maintenance-free bearings, these mixers excel in demanding environments - from activated sludge tanks to bioreactors and beyond.

Our hydrodynamically optimized swept-back impellers ensure superior mixing efficiency with self-cleaning capability, while premium materials like enhanced PU vanes and stainless-steel fittings resist corrosion and wear. With built-in leakage and overtemperature protection, along with IP68-rated waterproofing and continuous 24-hour operation, these units deliver durable performance, minimal downtime, and consistent flow control in municipal, industrial, and environmental applications.

Features

Motor

Squirrel-cage, induction motors are F class insulation, motor protection grade is IP68.

Mechanical seal

The mechanical seals protect the motor from contacting the pumping liquids. Two seals are in series with each other and individually work to provide the motor with a dual protection.

Auto-setter (options)

To allow pump for easy installation, maintenance & reparation, as it is no need to empty the tank first.

Non-clog impeller

Well statically & dynamically balanced Non-Clog impeller is designed to allow sizable spherical solids to pass the flow passage easily without clogging. It adopts rigorous technics so that vibration and noise can be farthest reduced.

Leakage detector

Built-in leakage detector in the oil chamber can detect leakage from the damage of the mechanical seal. (Less than 15 kW options, No less than 15kW standard). Built-in leakage detector in the wiring box and motor cavity of large power pumps can check if a leakage in it. The leakage detector offers pump an automatic protection (Not standard, No less than 132 kW options)

Heat-protector

Built-in heat protector in motor, can prevent the motor from burning out, overload & overheating. (Less than 15 kW options, No less than 15 kW standard). Built-in heat protector in bearing, when the bearing is abnormal and the temperature rises to disconneting temperature, the protector automatically cut off power supply to protect the bearing. (Not standard, no less than 18.5 kW options).

Cooling house (options)

Pumps make use of inner pressure of pump cavity to make liquid continully entering in space between cooling house and motor outer, to take away the heat of the motor. to make sure the regular work of the pump in low water level (No less than 18.5 kW options).
