SOUND VIBRATION EMITTED BY THE PUMP
Below are the results of the phonometric measurements carried out on the series pumps
.
These tests were carried out by an external laboratory in compliance with Directives and Standards UNI
EN ISO 3744:2009 and Directive ISO 2002/44/EC.

OPERATIONS TO BE PERFORMED ON THE HEAD
Periodical check of the head
Failures or malfunctions may occur due to negligence leading to extraordinary maintenance: proceeding
with a periodical visual check, as described in the
SR REDUCER manual, preventive maintenance
chapter
. It is, at times, possible to avoid the arising of situations that require extraordinary maintenance.
In the presence of these anomalies we recommend readily
intervening in order to avoid safety problems, a reduced flow
rate and reduced efficiency of the pump.
Summarising, the checks to be carried out are:
Periodical checks of the pumping head must be carried out to
ensure that the pump is safe and operating correctly.
Particular attention must be taken if the head installed is made
of plastic as it is more sensitive to temperature variations and
settling phenomena.
Check for oil leaks from the filler and drain caps, from the
diaphragm pinching or from the piston seal. Any one of these
leaks may initially cause a decrease in the flow rate, followed
by the breaking of the diaphragm at a later date.
Check for dosed liquid leaks from the valves.
