Systems
Epur Nature has designed a stand-alone system that can be used as a pumping station and, through gravity, i.e. no need for external source of energy, ensures the distribution of waters on a first or second stage filter, since the siphon is self-priming.
The system was manufactured, under a licence agreement, by a specialized firm and installed by our team.
