6.2 Spare parts
The decision on what spare parts to stock varies greatly
depending on many factors such as the criticality of the
application, the time required to buy and receive new
spares, the erosive/corrosive nature of the application,
and the cost of the spare part. Section 8 identifies all of
the components that make up each pump addressed in
this manual. Please refer to the Flowserve Durco Pump
Parts Catalog for more information. A copy of this book
can be obtained from your local Flowserve sales
engineer or distributor/representative.
6.2.1
Ordering of spare parts
Flowserve keeps records of all pumps that have been
supplied. Spare parts can be ordered from your local
Flowserve sales engineer or from a Flowserve
distributor or representative. When ordering spare
parts the following information should be supplied:
1) Pump serial number
2) Pump size and type
3) Part name – see section 8
4) Part item number – see section 8
5) Material of construction (alloy)
6) Number of parts required
The pump size and serial number can be found on the
nameplate located on the bearing housing. See
Figure 3-1.
6.3 Recommended spares and
consumable items
On critical services where down time is particularly
crucial it may be best to stock a spare pump or a
rotating assembly allowing service to be quickly
restored. The damaged pump or assembly could
then be repaired and serve as a back-up.
6.4 Tools required
Do not perform maintenance on a steel workbench.
The magnets present in the pump are strongly
attracted to ferrous materials. Use a non-metallic
(such as wood or plastic) workbench instead. The
use of non metallic tools is also recommended. A
typical range of tools that will be required to maintain
these pumps is listed below.
Standard hand tools

Hand wrenches (Metric and SAE)

Socket wrenches (Metric and SAE)

Allen wrenches (Metric and SAE)

Torque wrench (Metric and SAE)

Soft mallet

Screwdrivers
Specialized equipment

Bearing pullers

Bearing induction heaters

Dial indicators

Flowserve Tool Kit (ISO and ANSI)

Arbor or bench press

Eyebolt

M12x1.75 (Metric)

1/2 -13UNC (SAE)

Shaft for torque testing (see Figures 6-2 and 6-3)
To simplify maintenance, it is recommended that the
Flowserve Tool Kit (shown in Figure 6-1) is used.
This tool kit includes a specialized wrench, which
simplifies installation and removal of the outer magnet
assembly on long-coupled pumps.
This tool kit can be ordered from your local Flowserve
sales engineer or from a Flowserve distributor or
representative
