2. Stuffing Boxes with Mechanical Seals:
When mechanical seals are furnished the description and identification is indicated on the order
write ups which are part of the order acknowledgment, certified dimension print and the packing list.
Separate installation drawings which include startup and operating instructions will be found with
the instruction book attached to the pump.
The seal was installed at the factory and no further adjustment is required.
Specific instructions for preparation for operation, however, must be adhered to. Note particularly
the instructions pertaining to flushing, quenching, cooling and/or pressurizing. Failure to follow in-
structions may cause seal damage. Consult factory or seal representative if necessary.
3.4 Connection of equalizing piping
The equalizing pipe (102) and fittings are shipped separately in the box of fittings accompanying the
pump. The ends of the piping must be connected to the openings in the top of each stuffing box for
equalizing the pressure on the two boxes. See
7.3 Sectional view on page 31 . This piping must be used
on all units, including pumps fitted with single or double mechanical seals.
3.5 Connection of piping to quenching gland
The stuffing box gland can be operated with or without quenching water. Quenching is recommended on
applications where the liquid pumped is:
1. Hot water above 212°F
2. Between 250° and 350°F in addition to bearing housing cooling.
3. Volatile or toxic, in order to smother the gland leakage, which then can be piped away.
The quenching liquid must be from an outside source and should be piped with a flexible pipe,
into the opening in the upper gland half and allowed to drain into chamber or pocket in lower half
casing. The openings in the gland halves are tapped for ¼" pipe. A shut-off valve should be in-
stalled in each quenching line.
