Depreserving

It is recommended that a Flowserve
service representative be employed to inspect any
equipment stored for more than 12 months.
1) Clean petroleum-based preservative from all
parts of pump by using a petroleum-based
solvent such as kerosene or naphtha.
2) Depreserve bearing housings by performing the
following:
a) Remove bearings from housings
b) Flush bearing housings and piping with
clean lube oil and drain
c) Clean and reinstall bearings
3) Drain oil from the mechanical seals and seal
flush piping, then flush mechanical seals and
seal flush piping with appropriate fluid until clean.
4) See section 5.7 for additional start-up
information.
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 in accordance with local
removed and disposed of in accordance with current
local 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 local regulations at all times.

PUMP DESCRIPTION

This section describes the principal physical features
of your multistage barrel pump, as manufactured by
Flowserve. For an illustrative description of the
physical features of your pump, see Flowserve
drawings in the back of this manual; these drawings
define your as built/as shipped pump. Although this
section includes some description of equipment that
is purchased from a vendor and furnished with the
pump (notably the mechanical seal) as a rule, each
vendor presents his own descriptive information,
engineering drawings, installation instructions, etc.,
when it is necessary to familiarize operating and
maintenance personnel with the particulars of his
equipment (see section 8 and section 10).

Configurations

The cylindrical or barrel-like casing [1100] of your
barrel pump is centerline-mounted. The casing
houses a unitized internal assembly comprised of a
rotor (essentially, a shaft [2100] with equally spaced
impellers [2200] and a balance drum [6230]) and
stationary inner casings: intermediate cover [1460]
around each radial impeller, a suction spacer casing
[1130] at the first stage of the pump and a discharge
spacer casing-diffuser [1140] at the discharge stage
of the pump. An assembly rail [9363] that fits across
each casing holds them together for removal and
installation of the internal assembly. A guide in the
casing receives the assembly rail [9363]; rail and
guide, together, keep the inner casings from rotating.
There is a removable casing cover on the discharge
or outboard end of the pump casing. And there is
removable seal housing in the casing cover and the
inboard end of the casing. A seal unit is attached to,
or set in, each seal housing. Outside and at each
end of the casing, a bearing supports the radial load
of the shaft. In the same housing with the outboard
radial bearing, there is a thrust bearing that takes
the axial load of the rotor. (Lubricating oil for
bearings must satisfy specific requirements; see
section 5.2)
3.2

Name nomenclature

The pump nomenclature is:
6WIK1410 (Example Only)
The 6 is the pump discharge size
The WIK is pump type
The 14 is the nominal impeller diameter
The 10 is the number of stages

Design of major parts

3.3.1

Cartridge Assembly

The internal assembly, head, case end plate, seal
units, and bearing housings form a cartridge
assembly which is designed to be removed and
installed as a unit, thereby decreasing the amount of
time the pump will be out of service due to
mechanical failure. Instructions on removal and
installation of the cartridge assembly are contained
in section 6.7 and section 6.9.
3.3.2

Intermediate cover diffuser

The machined diffuser is an integral part of the
intermediate cover [1460]. This is necessary to
prevent the diffuser from rotating. Moreover, a
diffuser that is machined to the intermediate cover
[1460] is considered by Flowserve to be inseparable.
