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.
