Original Spare PartsThe same attention we pay to design andconstruction of our machines, is alsodedicated to the production of spare parts,so that each machine is able to ensure themaximum reliability and excellentperformance over time, without altering theproperties of the processed products. All Pieralisi original spare parts are builtaccording to the highest standards of qualityand covered by warranty. They can bepurchased directly by our service network orthrough the dedicated web portal:www.ricambioriginalipieralisi.com
Planned MaintenanceA proper maintenance plan makes it possibleto prevent and solve the problems related tothe normal machine wear, to ensure ongoinghigh performance and to maintain the value ofthe investment unchanged over time. Pieralisihas two solutions for planned maintenance: LIGHT is the standard option ideal for 2 to 4inspections at a fixed price; HEAVY is the special option that proposesthe replacement of the worn parts in additionto the 4 inspections.
SERVICE
Pieralisi Planned Maintenance is: CHEAPER, because it always offers a discounton the original spare parts used for allmaintenance operations and labor costs arereduced and protected from any rise; MORE EFFICIENT, because the prior checksand the related operations allow you tooptimize performance in terms of extractionyields and energy consumption; SAFER, because our maintenance operationsare conducted in compliance with the locallaws on safety. Moreover our specializedtechnicians always provides all necessaryinformation for the proper running of themachines; MORE FLEXIBLE, because our worldwideservice network is highly specialized andensures a qualified maintenance wherever themachines are located.
Extra MaintenanceIn order to maintain over time machines value,reliability and performance, we offer three typesof action, GOLD, SILVER and BRONZE,depending on the machine conditions. All operations are performed in Pieralisiproduction plant and covered by warranty.

WELL-KNOWN COMPANIES AND CONCERNS TRUST IN PIERALISI
A LEADER IN CENTRIFUGATION
PRINCIPLES OF THE SEPARATIONSYSTEM
The decanter is used for the
separation of two or more
phases of different specific
gravity, in particular for the
clarifying of liquids in which
suspended solids are
present. The separation of
solids and liquids takes place
within a cylindrical/conical
rotating bowl, upon the
periphery of which the
heavier solid phase collects
and is continually removed by
the internal conveyor.
A polyelectrolyte, suitably
chosen for its type and
specific characteristics, may
be added to the product
being fed to the machine in
order to improve the solid-
liquid separation.
The polyelectrolyte favours
the aggregation and thus the
easier capture of the solid
particles. A polyelectrolyte is
not always compatible with
products being processed.
It is generally used in
purification processes for the
drying of sludge, but not in
intermediate product
conversion processes, and
even less in the processing
of foodstuffs.
� Two- three-phase design
� Conveyor and bowl in
various stainless steels:
AISI 414, AISI 304
� Wear protection of
conveyor flights in tungsten
carbide
� Wear protection
(interchangeable) of
conveyor diffuser
� Fixed differential speed
variation.
STANDARDFEATURES
The electronic ROTOVARIATOR
is designed and manufactured
by the Pieralisi Group and
patented worldwide for
application on Pieralisi
decanter centrifuges including
already installed and newly
produced ones. The
electronic ROTOVARIATOR
can be fitted to Pieralisi
decanter centrifuges being
used for both sludge
dewatering and any
separation process of a solid
from one or two liquids.
Thanks to the electronic Rotovariator
ROTOVARIATOR device it is
possible to:
� continuously vary the number
of screw revolutions in
relation to the bowl of the
decanter
� regulate the torque on the
decanter reduction gear to
the maximum levels allowed;
this allows to protect
transmission gears and to
adjust the rate of feed flow to
the decanter and/or the
screw differential speed.
