Electric motors:
a)closed three-‐phase, self-‐ventilated externally insulated in class F, IP55 protection, unified Standards IEC or
NEMA C.
b) flame proof three-‐phase compliant with Directive 2014/34/EC (ATEX).
c) externally self-‐ventilated closed single-‐phase.
d) externally self-‐ventilated closed direct current.
The pump-‐engine coupling is monobloc with adapter and appropriate pinion.
The speed variator Stoeber type R37.0000 or other brands with same features can be installed between the engine and the
reducer.
The Libellula 1/3" can be installed: on fixed base, on carrying frame, on trolley for electric motor, petrol or diesel with
driven handles or wraparoud.
The machine is provided with permanent PVC protection or metal net with connecting rod-‐handle system cover to prevent
accidents due to operator-‐moving parts contact. The permanent protection is locked and held in its right position by
fastening bolts.
The machine is provided with lifting hook suitable for handling the pump coupled with the engine supplied by the

6. USE
6.1 INTENDED USE
The pump is suitable for handling liquids or muds with solid parts in suspension.
The pump has dry functioning possibility at indeterminate time.
The Libellula 1/3" can also be suitable for the transfer of food liquids; in this case, the user must ascertain that
the materials in contact with the product are compliant to the relative Directives.
The machine is designed and manufactured so that the parts in contact with the product to be pumped can be
cleaned before each use; all coupling elements are smooth, without roughness or spaces where organic
materials can be stored; the surfaces in contact with food products can be easily cleaned and disinfected.
6.2 NON-‐INTENDED USE
The pump is not suitable for pumping dangerous, flammable liquids or that can generate a potentially explosive
atmosphere, except for the ATEX certified version. Should the pump be used for pumping particularly
dangerous chemical products for contact with persons or things, it will be necessary to check with the supplier,
the correct choice of the metal materials and of the elastomers of the pump parts that come into contact with
the fluid. It will, however, be necessary for the installer to create a suitable basin in the operational area for
containing the fluid that might leak due to accidental breaking of the pumping diaphragm and install remove
controls for the machine start-‐up and switch-‐off and draining pipes of the fluids collection basin to enable
maintenance operations.
