Verify that equipment has been properly
shut off and rendered inoperative according
to plant safety protocol (e.g. lockout/tagout
procedures).
1
. Disassemble the pump seal chamber, in
accordance with the pump OEM instructions, to
expose the existing seal.
Document how the seal chamber is
disassembled for re-assembly.
2
. Carefully remove the existing sealing device,
taking care not to damage the shaft.
3
. Clean the shaft, shaft sleeve (if present), and
seal chamber face of rust, burrs, grit, sharp
edges, and set screw damage using fine emery
cloth. Wipe clean.
Avoid making flat spots or reducing the
shaft diameter.
4
. If the pump is equipped with a shaft sleeve,
verify the condition of its O-ring or gasket and
ensure that it is properly located (fully engaged
against step/hook/snap ring).
5
. Sealing surfaces and the shaft or shaft sleeve
must have at least a 63 Ra-
µ
in surface finish as
seen in
