Installation, Operation & Maintenance Manual
Model 53BTX Duplex Strainer, Sizes ¾” – 4”
BASKET REMOVAL AND CLEANING
A differential pressure increase of 5 psi across the strainer
indicates that the basket in operation is full of debris and
needs to be removed and cleaned.
CAUTION: To prevent damage to the baskets,
DO NOT permit the differential pressure across
the strainer to exceed 20 psi.
1. Transfer flow from the basket well in operation to the
opposite basket well. Refer to Switching Flow. Open the
drain valve.
2. To service the basket well, slowly open the cover vent and
drain or pressure equalizer valve (if installed). This relieves
the pressure and drains the fluid in that basket well.
3. When pressure is relieved and fluid drained, open the
basket well cover by turning the eye nuts counterclockwise
to end of studs. Lift cover up by the tabs until cover is free
of basket well and rotate cover counterclockwise, clearing
the basket well.
4. Remove the debris-laden basket. Invert the basket and
wash out the debris. Direct a stream of air or water from
the exterior of the basket to the interior. Note: Do not
permit the basket debris to dry, as it would be difficult to
remove and clean the basket. Inspect basket at each
cleaning for holes or tears. Replace as needed with
genuine Eaton strainer baskets.
BASKET REPLACEMENT
1. Place the cleaned or new basket into the basket well. Be
sure basket handle is sufficiently high to be compressed by
the cover. Refer to Receiving, Handling, and Inspection.
Inspect cover O-ring and sealing surface. Clean sealing
surface and replace O-ring as necessary. Reseat the cover.
Refer to Receiving, Handling and Inspection.
2. Close drain valve and open pressure equalizer and cover
vent valves of basket well just serviced. Open the pressure-
equalizing valve of the basket well in operation filling the
serviced basket well with fluid. Then close cover vent valve
when air is expelled. Next, close both pressure equalizing
valves.
SHUT DOWN
1. Slowly close the pipeline valves upstream and downstream
from the duplex strainer. Make sure these valves are
tightly closed.
2. To relieve fluid pressure in the strainer, first open the drain
valve. Then slowly open the pressure equalizer and cover
vent valves.
3. Proceed to clean and inspect each basket. Inspect the
strainer to insure there is no standing fluid.
