CAUTION
In the presence of heavy uses (concentrated corrosive liquids or liquids that crystallise), it is necessary to
increase the frequency of operations.
CAUTION: risk of internal back-pressures and projection of components during disassembly.
In severe conditions (incorrect installations and/or stops and/or in stall conditions), residual pressures inside
the pump can be generated which are not discharged. Before opening and disassembling the pump, it is
necessary to secure the pump casings with a suitable ratchet strap and wear suitable Personal Protective
Equipment (PPE).
