The PM series of single-screw pumps is entirely made of
AISI 304 steel : they are suitable for the conveyance of entire,
destemmed and pressed grapes, fermented grape-dregs,
must as well as various foodstuffs. The screw which is placed
in the loading hopper conveys the product inside the
tator, where the helical rotor pushes it into the outgoing pipes.
The PM pumps, through this mechanism, manage to
develop considerablepressures (aprox. 6 BAR).
