In biogas plants, pumps and agitators must work with highly viscous, solid-containing and sometimes aggressive substrates. HOMA works in this area with experienced partners who develop specialised biogas agitators. HOMA stainless steel pumps from the CTP series are used to convey silage effluent. They are corrosion-resistant, low-maintenance and have been used successfully in over 200 plants for many years. These pumps ensure safe, continuous conveyance and help to make the operation of biogas plants efficient and trouble-free.
