Pump Technology for Reliable Conveyance Processes in Biogas Plants

Pump Technology for Biogas Plants

The right pump technology for biogas plants ensures that manure, fermentation substrate, recirculated fluid, and viscous and solids-laden media are reliably conveyed. We design, supply, install, and optimize pump solutions for a variety of pumping applications. In doing so, we take into account the fluid, the required flow rate, the discharge pressure, the piping system, the pumping distance, and any differences in elevation.

No two biogas plants are alike. That is why we assess the entire plant situation before recommending a pump solution.

Eccentric screw pumps for
ly viscous fluids

Eccentric screw pumps are suitable for the uniform conveyance of liquid manure, fermentation substrate, and organic suspensions. Key factors for reliable operation include the appropriate rotational speed, protection against dry running, and a rotor-stator design tailored to the solids content and abrasiveness of the medium.

  • Consistent and low-pulsation pumping
  • Suitable for viscous and solids-laden media
  • Reliable pumping over long distances
  • Customized design for the specific medium and plant operation

Suitable for

Biogas plants with viscous and solids-laden process fluids

Rotary lobe pumps and central pump systems

Rotary lobe pumps are compact, robust, and versatile. They are suitable for pumping, transferring, recirculating, and feeding, and can often pump in both directions. In custom-designed central pumping systems, multiple tanks and flow paths can be served via a coordinated network of piping, valves, and control systems. The systems can also be designed for longer distances and greater elevation differences.

  • Flexible Conveying and Transfer Applications
  • Compact and robust design
  • Integration into existing systems
  • Plannable replacement of wear parts

Suitable for

Tanks with membrane roofs

Tanks with concrete roofs

Wet Shredding for Pumpable Substrates

Fibrous substrates and foreign matter can put a strain on pumps, valves, and piping. Appropriate wet pulverization breaks down fibrous structures, improves pumpability, and reduces the risk of blockages. Depending on the system design, we combine pumps with pulverization and foreign-matter separation technology.

  • Improved pumpability of fiber-rich substrates
  • Reduced risk of clogging
  • Protection of pumps, valves, and piping
  • Production of a homogeneous and pumpable suspension

Suitable for

Container with a plastic roof

Container with a concrete roof

Which pump is suitable for a biogas plant?

The choice of pump for a biogas plant depends on the fluid being pumped, the substrate composition, the required flow rate, and the plant’s operating conditions. Different pump systems are used depending on the application. We take a customized approach to your biogas plant and its specific requirements and select a pumping system that ensures reliable and efficient substrate transport.

Pumps in biogas plants can become clogged if fibrous or coarse components, foreign objects, or substrates that are difficult to pump enter the pump system. Pump technology that is not properly matched to the pumped medium can also lead to malfunctions and increased wear. Proper pump design and targeted substrate preparation help reduce clogging and support reliable plant operation.

Wet grinding prepares the substrate before it enters the pump and breaks down unwanted solids and fibers. This allows the pumped medium to be processed more evenly and reduces the risk of clogs or malfunctions in the pump system. At the same time, wet grinding can protect pumps and downstream plant components from unnecessary strain.

Yes, we offer pre-assembled pump systems in a containerized design for biogas plants. The necessary components are integrated into a compact, functional unit and designed for the specific application. This simplifies the integration of the pump technology into existing or new plants and enables a well-planned, plant-specific solution.

A pump in a biogas plant should be inspected and, if necessary, replaced if its flow rate decreases significantly, malfunctions occur repeatedly, or wear and repair costs increase. Changes in substrate composition, increased flow rate requirements, or a plant modernization may also make replacement advisable. We’ll assess your existing pump system and help you find a technically and economically suitable solution for your plant.
