DECANTER CENTRIFUGES for industrial use

Division Separation Solutions A LEADER IN CENTRIFUGATION The Pieralisi Group provides solutions to all technological problems of solid-liquid and solid-liquid-liquid separation, thanks to the great experience and know-how developed over time in the most important industrial centrifuge markets. Over 40,000 Pieralisi machines and plants are today installed worldwide, being used in a wide variety of centrifugal technology applications, as evidence of the undisputed market leadership of the Pieralisi Group. PRINCIPLES OF THE SEPARATION SYSTEM 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 solidliquid 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.

Division Separation Solutions SERVICE Original Spare Parts The same attention we pay to design and construction of our machines, is also dedicated to the production of spare parts, so that each machine is able to ensure the maximum reliability and excellent performance over time, without altering the properties of the processed products. All Pieralisi original spare parts are built according to the highest standards of quality and covered by warranty. They can be purchased directly by our service network or through the dedicated web portal: www.ricambioriginalipieralisi.com Planned Maintenance A proper maintenance plan makes it possible to prevent and solve the problems related to the normal machine wear, to ensure ongoing high performance and to maintain the value of the investment unchanged over time. Pieralisi has two solutions for planned maintenance: LIGHT is the standard option ideal for 2 to 4 inspections at a fixed price; HEAVY is the special option that proposes the replacement of the worn parts in addition to the 4 inspections. Pieralisi Planned Maintenance is: CHEAPER, because it always offers a discount on the original spare parts used for all maintenance operations and labor costs are reduced and protected from any rise; MORE EFFICIENT, because the prior checks and the related operations allow you to optimize performance in terms of extraction yields and energy consumption; SAFER, because our maintenance operations are conducted in compliance with the local laws on safety. Moreover our specialized technicians always provides all necessary information for the proper running of the machines; MORE FLEXIBLE, because our worldwide service network is highly specialized and ensures a qualified maintenance wherever the machines are located. Extra Maintenance In order to maintain over time machines value, reliability and performance, we offer three types of action, GOLD, SILVER and BRONZE, depending, on the machine conditions. All operations are performed in Pieralisi production plant and covered by warranty. 3183.1.2043-04/14-100 Printed by: Tecnostampa - Loreto (Italy) Technical features are not binding.
