Sewage pumps with cutter system - Barracuda GRP56 / GRP76 / GRP111


The installation of conventional sewer systems in areas of low population like small villages, farms or under difficult topographic conditions is often extremely expensive, mainly because of the high cost for large diameter pipework installation. HOMA provides the perfect, economical alternative with Barracuda grinder pump pressure sewage systems. The Barracuda pumps cut all solids present in the sewage into small particles. This allows the use of pipes from 50 mm diameter, which can be easily laid at low cost with a minimum of construction work.


Permanent with auto coupling system or with ringbase stand.
