All parts shall be properly packed to avoid any damage in transit, and accompanied by:
• reference to the purchase order;
• machine serial number;
• part code number;
• detailed description of the defect and how it was discovered;
• authorization module to the document completed and approved.

1.3.2 Testing
Before shipment all of our machines are accurately tested at GEA Niro Soavi premises by qualied
personnel through operational tests which simulate the normal working conditions.
Through the operational tests - run with cold water - it is possible to verify the actual performance
of the machine against the design data, the calibration of safety, control and check devices, the
conditions of any seals, as well as the noise and vibration-free operation of the machine and the
parameters introduced in any programmable instruments or equipment that might be used.
To test the performance of the machine (ow rate with the maximum operating pressure allowed,
noise level, electric absorption) the machine is run with water at a temperature of approximately 20
°C, so it is possible to verify the deviation of the machine’s actual ow rate compared to the rated
value ± 5% with product, according to the different temperatures and viscosity of the product treated.

2.1 General description
The GEA Niro Soavi homogenizer consists of a positive-displacement piston pump provided with
automatic valves with suction and delivery spring, connected to a homogenizing section where the
product undergoes the process of high-pressure micronization to reduce the size of the solid particles
suspended in the uids and achieve homogeneous dimensional distribution.
This process can be applied to a wide range of products of varying viscosities, and yields more
stable suspensions by micronizing and dispersing the particles, depending on the pressure.
For the specic conguration of the machine, model, technical data, accessories and optional
equipment, refer to the TECHNICAL SPECIFICATIONS enclosed with Chapter 11 of this manual.
CAUTION
The machine may not be utilised for any other purpose than that given in Chapter 3.1 of this
manual. The manufacturer is not liable for damage or injury resulting from improper use.
2.1.1 Operating principle
