3.3 Performance and operation limits
3.3.1 Alloy cross reference chart
Figure 3-2 is the Alloy cross-reference chart for
Flowserve ASME (ANSI) pumps.
This product has been selected to meet the
specification of your purchase order. See section 1.5.
Figure 3-3 is the Alloy cross reference chart for
wrought casing blind covers.
The following data is included as additional information
to help with your installation. It is typical, and factors
such as liquid being pumped, temperature, material of
construction, and seal type may influence this data. If
required, a definitive statement for your application can
be obtained from Flowserve.
3.3.2 Pressure-temperature ratings
The pressure–temperature (P-T) ratings for blind
covers are shown in figure 3-4. Determine the
appropriate cover “Material Group No.” in Figure 3-2.
Interpolation may be used to find the pressure rating
for a specific temperature.
The following provides pressure-
temperature ratings for the blind covers only.
The lowest rating of all parts connected to the
casing must be used. Consult the user
instructions provided with the pump.
Example:
The pressure temperature rating for a Mark 3 GP2
blind cover, 316 construction, with an operating
temperature of 149˚C is found as follows:
a) From Figure 3-2, the correct material group is 2.2
Cover plate material compatibility is
the responsibility of the end user.
b) From Figure 3-4C, the pressure-temperature
rating is 21.5 bar.
