SEEPEX supports sustainable energy production through anaerobic digestion
Reliable feedstock handling is becoming critical for UK anaerobic digestion( AD) plants as operators aim to maximise throughput, improve stability and increase renewable gas output under increasingly variable conditions.
Biomethane produced from agricultural residues, food waste, sewage sludge and other organic materials supports the decarbonisation of heat, transport and industry. Continued investment in anaerobic digestion infrastructure is driving demand for robust process technologies that maintain high availability and stable performance under demanding feed conditions.
SEEPEX technology enables efficient biogas production
Effective pretreatment and feeding of biomass slurries is essential for maximising biogas yield. SEEPEX progressive cavity pumps and
BTEX hopper pump for biogas substrate feeding, engineered for contaminated media with easy cleaning, fast maintenance and high reliability in tough conditions.
SCT pump enables quick in-place maintenance and longer service life, reducing downtime and operating costs in biogas applications.

macerators ensure a controlled and continuous feed of pretreated material into the digester. Maceration reduces particle size and increases surface area, improving microbial access and fermentation stability.
AD plants routinely handle fibrous agricultural residues, manure, bedding, food waste, sand, stones and wood fragments. These materials increase wear, blockages and maintenance demand across conveying systems.
SEEPEX addresses these challenges through reinforced materials, optimised hopper geometry, integrated solids separation zones and abrasion resistant components.
Maintenance efficiency is further improved with Smart Conveying Technology( SCT), featuring a twopiece stator and rotor design that enables servicing without pipework removal, reducing downtime by up to 85 percent.
Expanded BTEX and BN pump ranges for higher throughput
SEEPEX has extended its BTEX and BN pump portfolio to capacities from 5 to 160 m ³/ h at pressures up to 8 bar, supporting agricultural digesters, food waste plants and co-digestion facilities.
The BTEX design provides effective premixing, blending dry and fibrous solids with liquids before pumping. This reduces sedimentation, improves process stability and supports more consistent digester loading. Operators benefit from lower internal mixing demand, improved flow consistency and enhanced gas yield potential.
“ The combination of high flow rates, robust construction, efficient premixing and maintenance friendly technology makes the pumps an ideal solution for operators wishing to increase throughput and run processes more reliably,” says Bernd- Guntram Schulz, Product and Market Manager Biogas at SEEPEX.
With higher capacities, improved substrate conditioning and wear resistant design, SEEPEX continues to support the anaerobic digestion industry in improving operational efficiency and renewable energy production.
