prevent loss of load; the radius of curves must be as large as possible to
prevent loss of load especially in the infeed stage and to avoid noise
problems at delivery.
• we recommend you install a pressure gauge near the area where product is
fed into the homogenizer / piston pump in order to check infeed pressure; this
pressure gauge can be supplied as an optional by NIRO SOAVI and can be
standard, with minimum contact or with continuous analog signal for remote
control.
• if filters need to be installed on the feeding line, you must allow a clear area
at least 3 times the size of the pipe used; you also need to install a pressure
gauge downstream the filter to check actual infeed pressure and prevent filter
clogging and danger of cavitation of the machine. For cleaning purposes we
recommend installing parallel filters to be used alternatingly.
• every homogenizer or piston pump is characterized by pulsating operation:
for this reason, depending on the kind of system and machine flow, we
recommend you install a pulsation damper both for suction and delivery
(providing up to 20 bar maximum counterpressure on the line)
• the pulsation damper is always recommended for flow rates exceeding
5000÷6000 l/h; on the suction end, it must be installed as close as possible to
the machine inlet, while on the delivery end it must be installed on a
horizontal pipe at a distance of minimum 1 meter from adjacent bends. For
technical details about size and installation please contact NIRO SOAVI
• the pulsation damper must be installed in a vertical position; do not install the
damper so that the flow enters the damper directly, otherwise the damper will
fill up too quickly and become less effective as no air will be left at the top
• if the feed pump is connected to a tank, ensure that no air is sucked in by the
suction inlet through the creation of vortices by fitting suitable internal barriers
to divert the flow; the feeding pump must have a net positive suction head at
all times
• we recommend you install a suitable safety valve downstream the
homogenizer or piston pump in order to protect the system from possible
overpressure caused by inexperience or incorrect operation procedures
downstream the machine; the safety valve fitted in the machine, even where
a piston pump is used, will protect the machine, but not the system to which it
is connected, in case of dangerous overpressure.
