Introduction
Revello peristaltic pumps are based on the
principle of peristalsis according to which
the prevalence of the fluid treated is given
by a crushing sliding along the pipe. With
this method, more or less dense liquids are
transported in a delicate and soft manner.
The pumps are suitable for the pouring of
liquids (wine, fruit juices, milk, and oil) and
semi-solid products (crushed and intact
grapes, grapes after the removal
of stalks).
The pumps consist of a rotor bearing two
rollers which compress the rubber pipe,
while rotating, causing the
advancement of the liquid. Alternating
between compression and decompression
of the pipe generates a vacuum which
sucks the product resulting in a constant
flow.
The advantages of this type of pumps
produce a delicate pumping process that
prevents oxidization, shaking emulsions,
crushing of berries and seeds, and
contacts between the product and
mechanical parts.
