The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.
2.4.1 Storage – General
Normal packaging is designed to protect the pump
and parts during shipment and for dry, indoor
storage for up to six months or less. The following is
an overview of our normal packaging:
•
All loose unmounted items are packaged in a
water proof plastic bag and placed under the
coupling guard
•
Inner surfaces of the bearing housing, shaft (area
through bearing housing) and bearings are coated
with Cortec VCI-329 rust inhibitor, or equal.
Bearing housings are not filled with oil
prior to shipment
•
The internal surfaces of ferrous casings, covers,
seal chamber, flange faces, and the impeller
surface are sprayed with Cortec VCI-389, or
equal
•
Exposed shafts are taped with Polywrap
•
Flange covers are secured to both the suction
and discharge flanges or face.
•
In some cases with assemblies ordered with
external piping, components may be
disassembled for shipment
•
The pump must be stored in a covered, dry
location
2.4.2 Storage – Long Term
Long term storage is defined as more than six
months, but less than 12 months. The procedure
Flowserve follows for long term storage of pumps is
given below. These procedures are in addition to
the short term procedure.
•
Each assembly is hermetically (heat) sealed
from the atmosphere by means of tack wrap
sheeting and rubber bushings (mounting holes)
•
Desiccant bags are placed inside the tack
wrapped packaging
•
A solid wood box is used to cover the assembly
This packaging will provide protection for up to
twelve months from humidity, salt laden air, dust etc.
Warranty for the pumps will normally be for
12 months. Extension of this period can only be
achieved with the prior agreement of Flowserve
and would necessitate inspection prior to putting
the pump into service.
After unpacking, protection will be the responsibility of
the user. Addition of oil to the bearing housing will
remove the inhibitor. If units are to be idle for extended
periods after addition of lubricants, inhibitor oils should
be used. Every three months, the pump shaft should
be rotated approximately 10 revolutions.
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 regulations. If the
product contains substances that are harmful to the
environment, these should be 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.
3 DESCRIPTION
3.1 General
The Flowserve MPT single stage pump has a back
pull-out rotating assembly with suction and
discharge facings on the fixed casing to allow
removal of the rotating element without breaking the
pipe joints or moving the driver. Mounting feet are
rigidly connected to the casing so piping strains
allowed in section 2.3, Flange Loads, are readily
transmitted to the foundation.
No special tools are required for dismantling and
maintenance.
An example of the nameplate used on the MPT
pump, which is always mounted on the casing, is
shown below.
