1.7 Nameplate and safety labels
1.7.1 Nameplate
For details of nameplate, see the Declaration of
Conformity, or separate documentation included with
these User Instructions.
1.7.2 Safety labels
1.8 Specific machine performance
For performance parameters see section 1.5, Duty
conditions. Where performance data has been supplied
separately to the purchaser these should be obtained
and retained with these User Instructions.
1.9 Noise level
Attention must be given to the exposure of personnel
to the noise, and local legislation will define when
guidance to personnel on noise limitation is required,
and when noise exposure reduction is mandatory.
This is typically 80 to 85 dBA. The usual approach is
to control the exposure time to the noise or to enclose
the machine to reduce emitted sound.
You may have already specified a limiting noise level
when the equipment was ordered, however if no
noise requirements were defined, then attention is
drawn to the following table to give an indication of
equipment noise level so that you can take the
appropriate action in your plant.
Pump noise level is dependent on a number of
operational factors, flow rate, pipework design and
acoustic characteristics of the building, and so the
values given are subject to a 3 dBA tolerance and
cannot be guaranteed.
Similarly the motor noise provided in the table below is
“pump and motor” noise that is typically expected from
standard and high efficiency motors when on load
directly driving the pump. Note that a motor driven by
an inverter may show an increased noise at some
speeds.
If a pump unit only has been purchased for fitting with
your own driver, then the noise levels in the table should
be adjusted for the driver level obtained from the
supplier. Consult Flowserve or a noise specialist if
assistance is required in adjusting the values.
It is recommended that where exposure approaches
the prescribed limit, then site noise measurements
should be made
. The values are in sound pressure
level L
pA
at 1 m (3.3 ft) from th e machine, for “free
field conditions over a reflecting plane”.

Notes: (1.) values are for the maximum usable motor size (2.) for
1180 and 960 rpm reduce 1450 rpm values by 2 dBA. For 880 and
720 rpm reduce 1450 rpm values by 3 dBA. (3.) Choosing a fan-
cooled motor will increase noise levels. (4.) Placing valves, orifices,
or flow meters near a pump will increase noise levels inside the
pump.
For estimating sound power level L
WA
(re 1 pW) then
add 14 dBA to the sound pressure value.
2 TRANSPORT AND STORAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be
checked against the delivery/shipping documents for
its completeness and that there has been no damage
in transportation. Any shortage and/or damage must
