SEEPEX Pumps Empower Efficient Biogas Production

27 Jun 2025  |
Efficiently preparing and moving biomass slurry is essential in biogas production. SEEPEX macerators break down solid organic material, increasing surface area for microbes to convert it into biogas. Their progressive cavity pumps maintain a steady flow of pretreated slurry into the digester, optimizing fermentation and boosting biogas yield.

However, technical challenges can arise during slurry transfer, especially in agricultural environments with solid manure, straw, and stones, or industrial settings with glass debris. Sand and foreign objects like cow bedding can cause significant equipment wear. SEEPEX’s Easy Maintenance solutions address these challenges by reducing downtime and simplifying repairs, ensuring continuous, efficient operation even under tough conditions.

SEEPEX Smart Conveying Technology (SCT) is particularly valuable for biogas production. Its patented two-piece Smart Stator and Rotor design allows maintenance without removing pipework, reducing downtime by 85%. This ensures biogas plants operate efficiently with minimal interruptions. SCT’s integrated re-tensioning device adjusts the rotor-stator seal to compensate for wear, extending rotor and stator life by up to 200%, lowering costs, and improving long-term performance. The design also promotes easy recycling, further reducing environmental impact. The SCT Retrofit Kit offers cost-effective upgrades without modifying pipework, making it a sustainable solution for boosting productivity.

SEEPEX also excels at handling digestate, with pumps and macerators that move material efficiently through post-digestion steps. Products like the BTEX pump from SEEPEX’s T range perform reliably even in the toughest conditions, ensuring consistent biogas production.

SEEPEX offers not only high-quality pumps and macerators but also advanced control systems like the BGDC. These systems manage the dosing, mixing, and pumping of liquids and solids in biogas plants, ensuring optimal ratios and enhancing both safety and efficiency in biogas production.
