•
The internal surfaces of ferrous casings, covers,
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.
•
Assemblies ordered with external piping, in some
cases components may be disassembled for
shipment.
•
The pump must be stored in a covered, dry
location.
2.4.2
Long term storage
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.
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 and
greases 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 Configurations
The Durco G and H Series Magnetic Drive chemical
process pump are end suction, single stage,
centrifugal pumps. The horizontal family conforms to
ASME B73.3M, which has a centerline discharge and
is represented by our Standard long-coupled, Close-
coupled (Group 1 only), and Unitized self-priming
variants.
3.2 Nomenclature
The pump size will be engraved on the nameplate
typically as below:
BG 1.5 x 1 - 62/5.00 RV
•
“BG” refers to the magnetic coupling size – see
Table 3-2.
•
“1.5” refers to the suction diameter (1.5 in.)
•
“1” refers to the discharge diameter (1.0 in.)
•
“62” refers to nominal impeller diameter (6 & 2/8 in.)
•
“5.00” refers to actual impeller diameter (5.00 in)
•
“RV” refers to Reverse Vane impeller. (Open
impeller design not available on Guardian G & H
series pumps.)
Pump design variation:
A = This pump has been redesigned from an earlier
version. The impeller and casing are no longer
interchangeable with the earlier version.
H = This pump is designed for a higher flow capacity
than another pump with the same basic
designation. (Examples: 4X3-10 and 4X3-10H;
6X4-10 and 6X4-10H).
An example of the nameplate used on the Guardian
G & H Series pump is shown below. This nameplate,
which is always mounted on the Guardian G & H
Series bearing housing, is shown in Figure 3-1.
