Damhusåen Biogas digester Allweiler Macerator ABM
In 2015, Copenhagen Pump was contacted by Damhusåen at Lynetteselskabet for a replacement of the existing broken macerator. The customer, who keeps data on spare parts consumption, informed us that the macerator had been the cheapest macerator in operation for over 20 years in the entire history of the Lynette community. It was therefore interesting that Allweiler's ABM macerator was still in production.
Digester operation of biomass is best achieved with a homogeneous biomass. For more than 20 years, the Damhusåen digester has used an Allweiler Macerator for this very purpose. The Macerator is of the Grinder type with rotating plates and is available with a capacity of more than 80 m3/h.
The Macerator ABM has a pump power that allows it to be inserted into short pipelines on tanks without the use of a pump, but in most cases the liquid is forced through the pump with an Allweiler progressive cavity pump.
Service
According to Damhusåen's records, the Allweiler ABM Macerator is the cheapest downsizer the Lynette community has ever operated. In 20 years, the blades have been changed twice and the shaft seal has been changed approximately every 4 years.
The macerator is operated about 8 hours a day.
