In areas where the staff has to intervene, remember
that when the level of the sound pressure is:
below 70 dBA: it is not necessary to take special
precautions.
above 70 dBA: people working continuously in
the machine room must be supplied with
protective devices against noise.
below 85 dBA: no particular measures need to
be taken for casual visitors staying in the room
during a limited period.
above 85 dBA: the room must be considered as
a dangerous area because of the noise and a
warning sign must be fixed at each entry warning
the people coming into the room, even for a
short period, that they must wear hearing
protection.
above 105 dBA: special hearing protection
adapted to this noise level and to the spectral
noise components must be installed and a
warning sign to this effect erected at each entry.
The staff in the room must wear ear protection.
Make sure that the noise, which travels through the
walls and windows, does not generate too high noise
levels in the machine room's surroundings.
2 TRANSPORT AND STORAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be
checked against the delivery and shipping
documents for its completeness and that there has
been no damage in transportation.
Any shortage and or damage must be reported
immediately to Flowserve and received in writing
within one month of receipt of the equipment. Later
claims cannot be accepted.
Check any crate, boxes and wrappings for any
accessories or spare parts that may be packed
separately with the equipment or attached to
sidewalls of the box or equipment.
Each product has a unique serial number. Check
that this number corresponds with that advised and
always quote this number in correspondence as well
as when ordering spare parts or further accessories.
2.2 Handling
2.2.1 General instructions concerning handling
Boxes, crates, pallets or cartons may be unloaded
using forklift vehicles or slings dependent on their
size and construction. See 2.3.1 for positioning of
slings.
To lift heavy pieces above 25 kg (55 lb), use a winch
adapted to the mass and in accordance with the
current local regulations.
To lift machines or pieces with one or several
suspension rings, only use hooks and chains in
compliance with the local regulations concerning
safety.
Never put cables, chains or ropes directly on or in
the suspension rings. Cables, chains or lifting ropes
must never present excessive bending.
Never bend the lifting hooks, suspension rings,
chains, etc., which should only be made to endure
stresses within, calculated limits. Remember that the
capacity of a lifting device decreases when the
direction of the lifting force direction makes an angle
with the device axis.
To increase the safety and the efficiency of the lifting
device, all the lifting elements must be as
perpendicular as possible. If necessary a lifting beam
can be placed between the winch and the load.
When heavy pieces are lifted up, never stay or work
under the load or in the area, which could be in the
path of the load if it were to swing or fall away. Never
leave a load hanging from a winch. The acceleration
or the slowing-down of lifting equipment must stay in
the safety limits for the staff.
A winch must be positioned in such a way that the
load will be raised perpendicularly. Where possible
necessary precautions must be taken to avoid the
swing of the load, using for example two winches
making approximately the same angle, below 30°,
with the vertical.

All motors (for masses see the motor
description plate) must be handled with a winch.
For masses above 25 kg (55 lb), manual
handling is forbidden.
2.3 Lifting
2.3.1 Slinging of motor pumps units
Use handling means in accordance with motor
pump unit mass mentioned on the CE plate. For the
masses of the pumps bare end of shaft see table §
2.2.2 and nameplate.
To avoid distortion, the pump unit
should be lifted as shown.
