Leak-Proof Vertical Reducer | Energy-Saving Stepless Frequency Control | PEL Surface Aerator
Product Overview
The PEL Pump E-Type Vertical Surface Aerator (also known as a rotary disk aerator) is a critical horizontal-shaft surface aeration device specifically engineered for oxidation ditch processes and aeration tank oxygenation in sewage treatment plants. This comprehensive system includes an electric motor, vertical reducer, cross-slider coupling, main shaft, and Pump E-type impeller.
Driven by the transmission system, the impeller positioned just below the water surface forcefully agitates wastewater. The resulting vortex draws in and expels wastewater, creating a hydraulic jump that engulfs massive amounts of air. This process ensures complete mixing of wastewater and oxygen to facilitate highly efficient biochemical treatment while providing powerful oxygenation and driving wastewater circulation to prevent activated sludge settling.

Key Applications
Core Oxygenation in Sewage Treatment Plants: Primarily used for oxygenation in aeration tanks to thoroughly mix sewage with activated sludge and maintain suspension. Vital component in oxidation ditch processes with additional applications in pre-aeration, aerated grit chambers, and aerated flotation structures.
Ecological Restoration of Natural Water Bodies: The robust upper and lower water circulation generated during operation effectively disperses surface algae, foam, scum, and other substances, redissolving them into the water for recycling. Provides highly efficient mechanical destratification and purification for rivers and ponds.
Frequently Asked Questions
Traditional horizontal aeration equipment is prone to oil leaks at the shaft end. How does this vertical aerator solve this major pain point?
The PEL surface aerator innovatively utilizes a dedicated vertical reducer that is highly compact and lightweight. This vertical structural design completely eliminates the need for horizontal oil seals, fundamentally eradicating the possibility of oil leakage at the input shaft end found in horizontal structures. This design drastically improves environmental safety and operational reliability.
How does the equipment perform regarding daily maintenance and energy consumption?
Maintenance is incredibly simple and operation is highly energy-efficient. Mechanically, the output end of the reducer uses a cross-slider coupling with no axial connection to the impeller, making assembly and disassembly exceptionally convenient. Operationally, the equipment applies advanced frequency modulation technology to achieve stepless speed regulation of the impeller. Compared to traditional series excitation speed regulation, this new technology is far more energy-saving, reliable, and exceptionally easy to operate and maintain.
