2.4 Storage
If the pump will not be put immediately into service, it
should be stored in a dry room. To avoid any damage
during the storage period, the influence of any low or
high frequency vibration must be totally inhibited. If
the pump is delivered sealed in a plastic-wrapper, it is
of max. importance to avoid any damage of that
wrapper, because this will protect the pump against
humidity. Therefore it must be checked if this wrapper
has become cracked and if so, the wrapper must be
renewed. If a vertical pump will be stored in horizontal
position, be sure to support the pump sufficiently to
avoid any deformation or bending of the pump.
To avoid the presence of dust and humidity on the
driver, it shall also be wrapped in the same way.
2.4.1 Long period storage
If the pump is delivered in a plastic bag, the
preservations stand up for one year. If the storage
period exceeds this time, the preservation must be
checked and renewed. Also the air tight plastic bag
must be changed. Moreover we recommend to order
a Flowserve Service Engineer for checking the pump
before the first start up.
2.5 Recycling and end of product life
At the end of the service life of the product or its
parts, the relevant materials and parts should be
recycled or disposed of using an environmentally
acceptable method and local regulations. If the
product contains substances which are harmful to the
environment, these should be removed and disposed
of in accordance with current regulations. This also
includes the liquids and or gases in the "seal system"
or other utilities.
Make sure that hazardous substances are
disposed of safety and that the correct personal
protective equipment is used. The safety
specifications must be in accordance with the current
regulations at all times.
3.0 DESCRIPTION
3.1 Configuration
The model WUC covers the highly engineered
specialty end of the Flowserve family of double
casing vertical turbine pumps. The pump line is
based on a modular system, thus providing maximum
design and operating flexibility. This is combined with
specific design features, including stiff shaft
construction, a self-contained axial thrust bearing
housing and pressure containing parts certified to
various international standards. Altogether, this
makes the WUC the pump of choice for the most
critical applications where space considerations or
marginal NPSHA values preclude the use of a
horizontal multistage pump.
Liquid is flowing through the suction flange of the
headstock and through the Can to the impellers. The
last stage impeller is discharging the liquid via the
column pipes, to the discharge flange. The thrust is
balanced by back wearing rings and balancing holes.
The headstock is equipped with a drain connection,
which allows to flush the Can with Nitrogen before
disassembly.
A vent connection for the suction is standard.
The sense of rotation of the pump is counter
clockwise (CCW), looking from the coupling to the
shaft end of the pump.
