Heavy-duty submersible chopper pump for biogas plants
In biogas plants and livestock farms, managing solid waste with long fibers can be challenging. Effective shredding and pumping solutions are necessary to handle manure, biogas digestate, and industrial wastewater efficiently.

Shreds and ejects long-fiber solids efficiently
The CHIOR SPH Submersible Chopping Pump, manufactured by WAMGROUP, is designed to handle the toughest waste management tasks in biogas plants and livestock farms. Its robust shear system effectively shreds long-fiber solids, ensuring continuous operation even under severe conditions. The pump features a high-efficiency, low-energy consumption motor, paired with a top suction system for enhanced lifting efficiency. The durable chopping system, composed of counter-knives, shear bars, and a counter rotor made from treated and hardened materials, prevents clogging and supports reliable performance. The modular design allows for easy maintenance, and various accessory kits offer flexible installation options for specific applications. Key technical specifications include a submersible IE3 electric motor with IP68 protection, thermal probes to prevent overheating, and a cemented carbide mechanical seal for durability.
