IMPORTANT !
IF WATER LEAKAGE FROM THE DRAIN HOLE IN THE VOLUTE IS NOTICED, THE
IMPELLER MUST BE REMOVED AND THE MECHANICAL SEAL MUST BE
INSPECTED.
WHENEVER A MECHANICAL SEAL IS REMOVED, IT MUST BE REPLACED WITH A
NEW SEAL.
6A.1 MECHANICAL SEAL (ALL EXCEPT TBP)
Mechanical Seal Removal (All Except TBP)
To expose the
mechanical seal, first
remove the:
❑
Pump suction head,
if included.
❑
Impeller - see head-
ing “Impeller (All
Except TBP)” on
page 95.
1.
From within the
pump head, and
using two jaw-type
puller tools (hook-
type), spaced 180°
apart, reach in and pry (pull) the seal ring from the pump shaft.
Note: On pump models CBP and 2CBP first remove the spring retainer. See Figure
6a-3: “Typical TBP Mechanical Seal Assembly” on page 106.

Place two hook-type tools or two small screw drivers, 180° apart, between
the diaphragm assembly and the stationary sealing face. Using steady,
gentle pressure, pry the diaphragm assembly from the shaft.
3.
Slide the short end of a 3/32” or 7/64” (2.5 mm - 3.0 mm) hex key between
the back side of the pump head and the pump shaft.
