Materials in contact with the additive
In the standard configuration, MultiFlow series pumps are supplied with the following materials:

PVDF/PP
INSTALLATION
Premise
This section describes the operations to be performed to install the pump, pipes and for the wiring. Read these
instructions carefully before starting any operations.
Follow the instructions below during pump installation:
Assembling the pump
Install the pump away from heat sources and in a dry place, at a maximum room temperature of 40°C. The minimum
temperature, in any case not lower than 0°C, depends on the type of product to be dispensed which must always remain in the
liquid state. Use the anchors supplied to secure the pump, or those most suitable for the type of support chosen.
The pump can be installed both above and below the level of the liquid contained in the tank. In the most frequent case of
mounting the pump above the tank, limit the height of the suction to within 1.5 meters of the liquid level. (see Fig. 2a). For
liquids which let out aggressive fumes, do not install the pump in direct contact with the fumes and take the necessary
precautions to prevent premature deterioration of the equipment.
In case of under head installation, i.e. with the pump placed below the liquid level of the tank, (Fig. 2b), siphoning may
occur. Periodically check the functionality of the injection valve as its excessive wear may lead to the additive entering
into the system by gravity even with the pump switched off. Should the problem persist, insert a suitably calibrated back
pressure valve C between the metering pump and the injection point as shown in Fig. 2b.

PTFE
Make sure the pump is turned off and that all the relative equipment is also turned off before starting work.
Stop immediately if anomalous events or warning signs arise. Only start work again when you are absolutely
certain that you have eliminated the cause of the problem.
Do not install the pump in dangerous places or in environments at risk of fire or explosion.
Avoid electrical hazards and liquid leaks. Never use a damaged or faulty pump.
