Automatic Rotary Bar Screen Cleaner
Anti-Jamming Design
The rake teeth are positioned at the center of the chain and operate in a reversed movement pattern, preventing hard debris from being forced to the bottom and jamming the chain or rake — ensuring more reliable continuous operation.
Overload Protection for Equipment Safety
An overload safety protection device installed on the sprocket at the reducer output shaft prevents damage caused by accidental overloads, enhancing system safety and longevity.
High-Efficiency Multi-Rake Cleaning
The rotary chain is equipped with multiple cleaning rakes, enabling rapid capture and removal of debris — resulting in thorough and highly efficient cleaning performance.
Simple Structure & Reliable Operation
The machine features a compact, well-engineered design for stable operation, easy installation and maintenance — significantly reducing lifecycle costs.
Intelligent Automated Control
Supports PLC interface and integration with other systems, enabling automated control such as timed operation, water level control and differential level control. In case of unexpected blockage, the device can automatically start without waiting for a service cycle.

- Application Conditions
Pretreatment at Wastewater Treatment Plant Inlet
Automatic rotary bar screens are typically installed at the headworks or inlet channel of wastewater treatment plants to intercept large suspended solids and floating debris, protecting downstream equipment such as pumps, grit chambers, and biological reactors from blockage or damage.
Pump Station Screening & Protection
At sewage lift stations (e.g., municipal or industrial wastewater pump stations), bar screens at the inlet prevent large debris from entering the pumps, reducing clogging frequency and ensuring continuous and reliable pump operation.
Combined Water Treatment System Pretreatment
In combined or separated sewer systems, automatic screens can be placed at junction points to capture solids and operate automatically during high flows, enhancing system resilience.
Industrial Wastewater Pretreatment
In industrial wastewater applications such as pulp & paper, food processing, textiles, and electroplating, screening removes larger solids before biological or chemical treatment units, reducing load and improving overall efficiency.
Rural/Small Town Sewage Collection Systems
Installing automatic rotary bar screens at small wastewater collection canal outlets or pump inlets reduces manual cleaning, saves labor, and increases automation reliability in decentralized systems.

Ebaps Vila Velha
- Espirito Santo State, Brazil
Customer/Owner: “Estacǎo de Bombeamento de Áquas Pluviais
- Working conditions/Challenges:
This pumping station is a rainwater drainage pumping station. As part of the city ‘s large-scale drainage/flood control infrastructure, it is equipped with approximately 12 kilometers of closed drainage pipe galleries + 7 kilometers of anti-seepage channels.
- The type of equipment adopted:
We provide three 900QZB-315KW submersible mixed-flow pumps with a diameter of φ1400mm for this project, along with three 2*4.7m automatic rotary screen cleaners, eleven electric gates and five flap valves.
Key indicators: A grille screen is installed in the intake channel of the pumping station to intercept large particles of debris and floating garbage, reducing the frequency of pump inlet blockage, thereby lowering maintenance costs and enhancing the stability of the pumping station.
