Suction Guides
Introduction
Suction Guides are designed for bolting
directly onto the suction flange of horizontal
or vertical shaft centrifugal pumps.
Operating Limits
The suction guide is designed to be a
four-
function
fitting. Each Suction Guide is a 90º
elbow, a Pipe Strainer and a Flow Stabilizer.
It may also be used as a Reducing Elbow,
should the suction piping be larger than the
pump inlet
.
Installation
The Suction Guides may be installed in any
arrangement feasible the arrangement of the
pump flange bolt-holes.
Inspection
Suction Guides are thoroughly tested and
inspected before shipment to assure they
meet with your order requirements. All units
must be carefully examined upon arrival for
possible damage during transit. Any evidence
of
mishandling
should
be
reported
immediately to the carrier and noted on the
freight bill.
Operation
No special attention need be paid to the
Suction Guide at start-up. The fitting is
stationary and will strain the pumped fluid
and stabilize the flow into the pump
automatically.
Temporary strainer must be removed
following system clean up
.
After all debris has been removed from the
system, or a maximum of 24 running hours,
stop the pump and close the pump isolation
valves. Drain the Suction Guide by removing
the drain plug or opening the blowdown
valve, if installed
Remove the Suction Guide cover and remove
the strainer assembly from the valve body.
A temporary fine-mesh start-up strainer is
tack-welded to the permanent stainless steel
strainer. This temporary strainer should now
be removed from the permanent strainer. The
fine-mesh strainer is designed to remove
small particulate from new piping systems
and could easily clog with debris if left in
