Overview of AS and AV Type Tear-Resistant Sewage Pumps

AS and AV series submersible sewage pumps incorporate advanced technology from the German company ABS, making them ideally suited for handling liquids containing hard solids and fibrous materials, as well as highly dirty, viscous, and slippery fluids. All AS pumps are equipped with a pre‑adjusted shredding mechanism that breaks down long fibers, bags, ribbons, grass, fabric, and other debris in wastewater before discharge. As a result, they operate without clogging and deliver exceptionally reliable performance.

The AS and AV series can be equipped, as required by the customer, with a dual-rail automatic coupling installation system, which greatly simplifies installation and maintenance, eliminating the need for personnel to enter the sewage pit.

Application Scope of AS and AV Type Tear-Resistant Sewage Pumps

AS and AV type cut‑type sewage pumps are suitable for conveying wastewater and sludge containing solid particles in industries such as chemical processing, petroleum, pharmaceuticals, mining, papermaking, power generation, as well as in urban sewage treatment, municipal engineering, and public‑facility drainage applications.

Product Features of AS and AV Type Tear-Resistant Sewage Pumps

1. Strong sewage discharge capacity and clog-free, capable of effectively passing solid particles with diameters ranging from φ30 to φ80 millimeters.

2. The shredding mechanism can tear and cut fibrous materials, allowing for smooth discharge without the need to install a filter screen on the pump.

3. The design is well-optimized, with a compact motor that delivers significant energy savings.

4. The mechanical seal made of new materials enables the pump to operate safely and continuously for more than 8,000 hours.

5. Compact structure, easy to move, simple installation, no need to construct a pump house, thereby reducing project costs.

6. Dual-rail automatic installation system, offering convenient installation and maintenance; personnel are not required to enter the sewage pit for these tasks.

7. The float switch can automatically start and stop the pump according to the desired water level changes, eliminating the need for dedicated supervision.

8. It can be equipped with a fully automatic protection control box to provide effective protection against leakage current, water ingress, and overload, thereby enhancing the product’s safety and reliability.
