Testing
Functional Testing
Pump Test Fixtures
Garlock Compression Packing has three different
pump test fxture designs used for evaluating pump
packing set types and arrangements.
Media:
Ambient temperature water
Note: The end suction pump system, due to the dynamics of a closed
loop system, can produce water temperatures as high as 160°F (70°C).
Abrasives
:
Can be introduced into the
end suction pump system
Shaft Speeds:
From 367 fpm to 2,100 fpm
(1.63 m/s to 9.33 m/s)
Packing cross sections:
Typically 3/8" (9.5 mm) cross
section, but modifcations
can be made to test up to
5/8" (15.8 mm) cross
section.
Stuffng box pressures:
2 psi to 120 psi (0.1 to 8.3
bar)
Note: Pressures above 60 psi (4.1 bar) are achieved by throttling down
the discharge fow in the end suction pump.
Stuffng box depths:
1.500" to 2.250" (38.1 mm to
57.2 mm)
High Temperature
/ Pressure Valve Test
Fixtures
The basic design layout for this fxture was pro-
duced by Dayton T. Brown (an independent test labora-
tory in Bohemia, New York) for sanctioned qualifcation
testing by the U.S. Military. Of four test valve positions,
two use custom-made valve bonnets in MOV-type test
scenarios, and two are standard production block valve
bonnets that are hand-actuated.
Material Testing
Material Testing Laboratory
The various testing capabilities are often used to
check conformance to ISO material and processing
specifcation requirements.
The Garlock Compression Packing facility has
the capability to perform a range of in-house chemical
and physical testing exercises. These tests are used
to qualify or to check the conformance of incoming
raw materials as an aid to in-process checks, or as a
fnal qualifcation check to ensure that fnished prod-
ucts meet the customer’s agreed-upon specifcations.
Whenever possible and practical, Garlock performs its
testing pro-grams in conformance with existing ASTM
procedures.
Examples of testing capabilities are:
• Wet chemical testing
• Weight loss determination
• Exposure—radiation, argon, etc.
• Yields—braid, ring
• Tensile strength
• Density determinations
