Hose pumps for biogas

LSM pumps have many years of experience delivering pumps to various farms within the agro industry, and as something new, we have started supplying pumps to biogas plants, where we pump biomass around the facility.

Biomass is a renewable organic material such as agricultural crops or municipal and industrial waste, by-products from food production or fats.

Examples of raw biomass from agriculture:

• Manure with feed residues, such as chopped straw or fiber

• Slurry from treatment plants

• Silage, corn, or sugar beets

• Harvested by-products such as straw, fruit, and vegetable waste

• Organic waste, meat, or fat from slaughterhouses

Biogas from container to tank

All these different media are pumped from their containers into a tank where heat is added to accelerate the process, allowing the necessary bacteria to develop. While heat is supplied, the biomass ferments for a while. During this time, all the biomass releases gases, which rise to the top where piping leads to a container that stores the biogas.
The biogas can then be sold to various heating plants, which burn the gases and use the heat to supply warmth to residents in the town.

The remaining biomass, called digested biomass, flows out from the bottom of the tank into another container, where it can then be used for fields if it is liquid like biogas slurry.

In this process, LSM hose pumps are used, among other things, to pump the raw biogas into the large tank where the fermentation process takes place. At larger plants, farmers often have several different containers with various types of raw biogas material. Here, it would be beneficial to invest in an LSM pump, which can be connected to the different containers and pump the raw biomass into the large tank where the process occurs.

Most traditional pump designs have difficulty handling biomass because it often contains a high amount of sand or other solid materials, including plant residues, straw, or similar, which tend to clog the pump pipe when the flow path changes.
