high solids, sand, fiber, bedding material, and debris—SEEPEX Easy Maintenance solutions reduce downtime and extend component life. Smart Conveying Technology (SCT) features a patented two-piece stator and rotor design that allows maintenance without removing pipework, cutting downtime by up to 85 percent. The integrated re-tensioning mechanism adjusts the sealing line as wear progresses, often doubling component life and lowering operating costs. SCT retrofit kits support economical upgrades of aging facilities.

NEW: Expanded BN and BTEX Pump Sizes for High-Volume RNG Operations

SEEPEX now offers flow capacities of 20–90, 40–180, 80–360, and a new high-capacity model delivering 180–700 gallons per hour at 60 to 120 psi.

These pumps provide stable, high-capacity transfer even during seasonal peaks or intensive feed cycles, making them ideal for large dairy digesters, food-waste co-digestion projects, and municipal sludge operations with fluctuating feedstock volumes. The robust design and optimized premixing ensure flexibility for agricultural digesters, industrial co-digestion plants, and municipal waste-to-energy facilities, particularly when combining solid and liquid substrates such as dry matter and manure.

Optimized Premixing Enhances Digester Efficiency

The BTEX hopper and inlet design blends dry, fibrous, or high-solid materials with liquids before pumping, improving handling of manure, bedding, and food waste while minimizing sedimentation and agglomerate formation. Operators benefit from more consistent microbial activity, faster fermentation, shorter retention times, and reduced energy use for internal mixing, resulting in higher methane production and greater RNG yield. Stable homogenization ensures reliable performance even when solids concentration fluctuates throughout the day.

Outlook

With the new BTEX and BN pump sizes, SEEPEX positions itself as a key partner for the next generation of U.S. biogas and biomethane facilities. Higher flow capacities, improved substrate preparation, and optimized pump technology help operators achieve greater efficiency, stability, and economic performance—particularly during seasonal or campaign-based substrate inputs. As RNG becomes increasingly important for U.S. decarbonization and energy security goals, reliable plant technology is more valuable than ever.

Bernd-Guntram Schulz, Product and Market Manager Biogas at SEEPEX summarizes: "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, reduce costs, and run their processes more reliably."
