Attention to dosed chemicals
! Before any operation on the pump, discharge the liquid from
the pump head and pipes. Take all necessary personal protective measures (i.e. gloves and
goggles), as indicated in the SDS of the chemical, which must be always available and updated.
Attention to splashes
! To prevent any leakage of the dosing liquid while operating on the
pump, for example during maintenance, before the intervention depressurize all hydraulic
components of the system.
It is advisable to install a discharge valve in the delivery line upstream of the pump, to prevent
overpressure or explosion of hydraulic components due to a block on the injection line.
Install the pump in an easily accessible place and respect the prescribed maintenance
schedule.
In Case of Emergency
In an emergency, unplug the pump or disconnect the power through the emergency stop switch,
depending on the installation.
In case of leakage of the dosed liquid, depressurize the hydraulic system and take the protective
measures indicated in the SDS of the chemical.
