Installation - Norms; Pump Engine/Motor Coupling - Bertolini C 300 Serie Manual De Usuario

The Bertolini pumps, concerning security, comply with the rule UNI EN 809 and are destined
to be coupled, directly or through a countershaft, with an electric motor, hydraulic motor or
gasoline engine.
The machine or the system where the pump is located must be perfectly built ob-
serving the current safety rules in the country where the machine is installed.
For Europe this is guaranteed by the CE mark and by the declaration of compli-
ance of the machine manufacturer.
A correct installation is the decisive factor for a good operation and for a long life
of the pump. The 90% of problems and malfunctions come from:
 Inadequate coupling between pump and engine/motor;
 Inadequate sizes of the inlet circuit;
 Inadequate quality or incorrect calibration of the pressure relief valve or unloader valve.
