A crane must be used for all pump sets in
excess of 25 kg (55 lb). Fully trained personnel must
carry out lifting, in accordance with local regulations.
2.4 Storage
Store the pump in a clean, dry location
away from vibration. Leave piping connection covers in
place to keep dirt and other foreign material out of pump
casing. Turn pump at intervals to prevent brinelling of
the bearings and the seal faces, if fitted, from sticking.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.
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 requirements. If the
product contains substances that 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 that may be used in
the "seal system" or other utilities.
Make sure that hazardous substances are
disposed of safely and that the correct personal
protective equipment is used. The safety
specifications must be in accordance with the current
regulations at all times.
3 DESCRIPTION
3.1 Configurations
The pump is a modular designed centrifugal pump
that can be built to achieve almost all chemical liquid
pumping requirements. (See 3.2 and 3.3 below.)
3.2 Name nomenclature
The pump size will be engraved on the nameplate
typically as below:
150CPXV-WW400A
Nominal casing discharge size * in mm
CPXV line shaft configuration
D-Line wet end material
WW - grey cast iron
CW - Alloy
Nominal ISO maximum impeller diameter in mm
(125, 160, 200, 250, 315, 400 or 500)
A - inducer fitted
* The soleplate discharge size is generally one or two standard
pipe diameters greater to keep pipe losses down and ensure high
efficiency.
The typical nomenclature above is the general guide
to the CPXV WW/CW configuration description.
Identify the actual pump size and serial number from
the pump nameplate. Check that this agrees with the
applicable certification provided.
3.3 Design of major parts
3.3.1 Pump casing
The pump casing is designed for operation when
submerged in the sump liquid.
3.3.2 Impeller
An enclosed impeller is fitted having balance holes.
Where applicable an inducer will be fitted in front of
the impeller.
3.3.3 Shaft
The shaft has a keyed drive coupling. It is supported by
rolling bearing(s) above the soleplate and journal
bearing(s) below.
3.3.4 Bearing housing
The bearing housing has a bearing carrier which is
preset.
3.3.5 Pump bearings and lubrication
The pump is fitted with a thrust type ball bearing that
may be configured differently dependent on use.
The thrust bearing(s) may be grease or oil lubricated.
The journal bearings may be lubricated by product or
from an external source.
3.3.6 Soleplate seal
The modular design enables one of a number of
sealing options to be fitted.
3.3.7 Driver
The pump is normally driven by a flange mounted electric
motor. An air or hydraulic motor may be utilized.
The position of the terminal box can be changed by
rotating the complete motor. To do this, remove the
fasteners from the motor flange, rotate the motor and
re-fit the fasteners.
3.3.8 Accessories
Accessories may be fitted when specified by the
customer.
