Bertolini pumps comply with the safety regulations laid down by standard EN 809 and are
designed to be coupled, either directly or via a transmission, to an electric, heat or hydraulic
motor.
The machine or system of which the pump is a part must be constructed in
accordance with good engineering practice and with the safety regulations in
force in the country in which the machine itself is installed.
In Europe, this condition is testified by the CE mark and by the declaration of
conformity provided by the machine manufacturer.
Correct installation is a key factor for the smooth running and long life of the
pump. 90% of faults and failures are caused by:
•
Incorrect pump-motor coupling.
•
Incorrect sizing or poor construction of the feeding circuit.
•
Poor quality or incorrect calibration of the maximum pressure or bypass valve.
Idromeccanica Bertolini declines all liability regarding failure to comply
with the following instructions:
4.1 Pump connection to the frame
The system must be installed on a stable, sound, safe base using the six M14 holes at the
base of the crankcase.
4.3 Pump-motor coupling
The manufacturer of the system is responsible for choosing and correctly
sizing the drive system, also in relation to the risks to people that the chosen
system could cause.
When connecting to electric motors, comply with the instructions given by standard
EN60204.1 against risks of an electrical nature.
To prevent their accidental contact with parts of the body, all moving components that
transmit motion from the motor to the pump must be adequately protected, as
specified in Machinery Directive 2006/42/EC or according to the regulations in force in
the country of use.
If the pump shaft has a double prime mover, the unused one must be suitably
protected.
If the transmission or shaft protection is damaged or breaks, stop the system
immediately and have it checked by a specialized technician.
Do not touch the shaft protection with the hands or feet during use.
