Submersible chopper pump for biogas plants
Optimize slurry management with a solution that efficiently shreds and pumps fibrous materials, transforming waste into valuable biogas and fertilizers while ensuring seamless integration into your existing processing line.

Shreds and Pumps Fibrous Slurry Efficiently
The CHIOR SPB from WAMGROUP is a submersible chopper pump engineered for challenging environments like biogas plants and livestock breeding operations. This pump excels in efficiently shredding and lifting fibrous and lumpy slurry, thanks to its innovative cutting system featuring sharpened helicoid blades and fixed knives. Suitable for applications in biogas production, manure treatment, and industrial wastewater, it ensures optimal material flow and prevention of clogging. The SPB operates continuously with high-speed, automatic performance and integrates seamlessly into existing processes. Built with a durable cast iron body and an IE3 electric motor, it offers low energy consumption and robust reliability. A thermal probe protects against overheating, while an anti-leakage design extends operational lifespan. With modular components, maintenance is straightforward, and the pump is adaptable to various configurations, whether mounted vertically or horizontally, making it a versatile solution for diverse industrial needs.
