Heavy-duty submersible chopper pump for biogas plants
Effectively manage fibrous waste and prevent clogging in demanding environments with this robust submersible chopper pump, engineered to shred and pump long-fiber solids with high efficiency and reliability.

Chops and Pumps Long-Fiber Solids Submersibly
The CHIOR SPH Submersible Chopping Pump by WAMGROUP is engineered for heavy-duty applications in challenging environments such as biogas plants and wastewater treatment facilities. This pump features a triple chopping system, using counter knives, shear bars, and a counter rotor, allowing it to effectively process long-fiber solids like livestock manure and biogas digestate continuously. It offers a submersible setup, supporting either vertical guide pole or free-standing installation, enhancing integration flexibility. Equipped with a premium efficiency IE3 electric motor, it ensures low-energy consumption while maintaining high lifting efficiency through its top suction system. Constructed from durable cast iron, the SPH pump resists wear and extends operational life, ideal for ejection and pumping of slurries and liquids under severe conditions. It meets rigorous anti-leakage and thermal protection standards, aided by a cemented carbide mechanical seal and an IP68 motor protection rating, ensuring reliable operation and reduced downtime. Accessories like the pole-mounting kit and 90° elbow offer further customization to meet specific production needs.
