vortex formation by using internal flow deviation barriers; the suction port must always be under
head
• It is always recommended to install a suitable pressure relief valve, downstream from the
homogenizing unit, to protect the system from any overpressure caused by incompetence or
incorrect operations on the system downstream from the machine; the pressure relief valve
installed on the machine is used to protect the machine and not the system to which it is connected
from any dangerous overpressure
• Never use the machine to drain a supply tank completely, in order to prevent a sudden lack of
product during pressure mode, but have at least a level sensor to cut off the pressure (in the case
of a homogenizing unit) and stop the machine before product stops being supplied
• The treated product must contain no air or gas, as this can lead to cavitation. If the product
contains air due its elevated viscosity or upstream processes, it must be de-aerated with special
equipment before entering the machine
• If the process temperature is greater than 90°C, the supply must be increased due to the increased
steam pressure, which can result in cavitation.
The supply pressure must therefore be increased by 1 bar every 5°C of temperature in excess of
90°C over the minimum supply pressure specified in the enclosed Technical Specifications Dossier.
This value must be doubled if the product's viscosity is in excess of 500 cP.
For special products and process temperatures, contact
GEA Niro Soavi.
The machine is equipped with automatic spring-loaded pumping valves, whose load is set in relation
to the product type. This means that if the machine is stopped or stops, and the supply line is open
and under pressure, the product may continue to flow through the machine. To be sure that no
product flows through the machine when its is stopped, the user must provide a check valve on the
supply line upstream of the machine
