Comprehensive Pump Range for Anaerobic Digestion Systems

Within the biogas market, PCM supports stakeholders in anaerobic digestion — including farming cooperatives, industrial players, and engineering firms — with tailored pumping systems. Many biogas plants are already equipped with PCM solutions.

To meet the specific technical requirements of feeding and digestate management, PCM has developed a comprehensive pump range focused on durability, abrasion resistance, and ease of maintenance:

• PCM X-BIO: engineered to transfer high-viscosity, high-dry-matter feedstock from the feed system to the digester.

• PCM EcoMoineau™ MX: ideal for transferring abrasive, particle-laden liquid digestate to hygienization systems and phase separators. It features a built-in maintenance system for quick rotor and stator replacement, extending service life and minimizing downtime.

PCM’s elastomer stators are specially formulated to withstand abrasive and particle-rich fluids while ensuring reliable performance.

Two innovative pump designs further expand the offering:

• Vertical storage tank pump: designed to transfer digestate to spreading systems, it ensures optimal pumping regardless of tank depth (up to 5 meters). An integrated foreign-body separation system protects the rotor, ensuring continuous operation.

• Adaptable hopper pump: a retrofit solution for existing systems, this progressive cavity pump with Archimedes screw enables efficient feedstock transfer. Its adaptability enhances process reliability and long-term performance.

With this complete and scalable range, PCM delivers robust, efficient, and future-ready pumping solutions for biogas production.
