6.5.7.1
Insert Orientation (Tee-Line Strainer)
Insert of the bucket strainer is to catch or filter foreign materials out of the
pumps, valves and process equipment to prevent blockage inside plumbing
and avoid damage to the pump. Upon performing preventive maintenance for
the bucket strainer, “insert” has to be installed into bucket strainer with correct
orientation, otherwise filtration is not effective.
Figure 6-6, 6-7, 6-8, 6-9
and
6-10
for guidance.
Refer
Figure 6-6, 6-7, 6-8 and 6-9
for liquid flow direction and insert orientation.
Note
: The CURVE surface of the “Insert” needs to be installed perpendicular to
the flow.
