MODEL 758G
Grooved-End “Wye” Strainer
SERVICE RECOMMENDATIONS
For use in water, oil & gas piping to provide economical protection for
pumps, meters, valves, compressors, traps & similar equipment.
SCREENS
Standard screens for Y-Strainer are perforated 304 Stainless Steel with spot
welded seam. Mesh lining is available in all alloys for extra fne straining.
Recommended standard perforations are listed below in the material
specifcations.
GRUVLOK STRAINER BASKET
Furnished as standard in sizes 8" (43 mm) and larger.
A one-quarter turn securely locks the screen in its seat
and frees the serviceman for securing the cover fange
to the body of the strainer.
Contact a Gruvlok Rep. for other applications.
CONSTRUCTION
All covers have an NPT
blowoff outlet at location
“C”. Recessed seat in the cover
ensures accurate screen alignment.
Bosses at the inlet and outlet fanges
are provided for gauge taps.
Self-cleaning is done by opening the valve or plug connected to the
blowoff outlet. (Advise when strainers are to be mounted in vertical piping,
so we can rotate the cover to position the blowoff at the lowest point.)
BLOWOFF OUTLETS
Tapped NPT size specifed in the dimension table. Blowoff outlets are not
normally furnished with plugs.
INDIVIDUALLY HYDROSTATICALLY TESTED
Working Pressures Non-Shock
640 PSI @ 150°F (45 Bar @ 65°C)
Flow data:
NOTE 1.
Most U.S. piping engineers specify system startup instructions for new systems which
include removing the pre-flter screen after system fushing of the main piping before the
system is put into normal operation. Flow data values are based on fow of clean water at
ambient temperatures. The pressure drop across the diffuser basket strainer, 50% clogged,
is approximately twice as great as that of a clean strainer.
NOTE 2.
Suction Diffuser baskets need a routine maintanence program to maintain system
effciency.
