The Sanicubic 2 lifting station consists
of two, 1-hp motors housed inside a
compact but highly durable plastic
enclosure. Each operating grinder
has its own high-performance
grinding system: a fast-rotating
blade to reduce solids in the
drainage stream from toilets,
tubs and showers, sinks, washing
machines, and dishwashers. The
two grinders operate alternately,
taking turns handling the incoming
waste so that neither is more heavily
used over time than the other.
