7. To gain access to the mechanical seal, it is necessary to remove the
stainless steel upper plate which is held in place by an O-ring located
under the plate rim. Place a small block of wood against the underside
of the rim and, while moving around the rim, tap with a mallet against
the block until the upper plate loosens. Remove the upper plate and
O-ring from the pump casing. Discard the O-ring.
8. Remove the stationary element from the upper plate. With a clean
cloth, wipe the upper plate bore clean and inspect for damage. Replace
the upper plate, as required.
9. Remove the top (vented) stainless steel inner casing. Grasp the pump
shaft, below the mechanical seal, and move it sharply back and forth
to free the first stage from the lower pump body. Remove the entire
stack assembly from the pump external sleeve.
10. Slide the mechanical seal rotary element, spring and washer from the
pump shaft. Discard the entire mechanical seal assembly.
11. Lubricate the inside of the new mechanical seal assembly with a
quality grade of O-ring lubricant.
12. To install a new mechanical seal rotary assembly, slide the assembly
onto the pump shaft, spring end first. Be sure the top spring tip is in
the hole of the rotary portion of the seal. DO NOT scratch or
otherwise damage the seal face. With a clean, lint free cloth, wipe the
seal face clean of all lubricant or debris.
13. Lubricate the outside of the new mechanical seal stationary element
with a quality grade of O-ring lubricant.
14. Insert the stationary seat into the seal housing with the seal face out.
DO NOT scratch or otherwise damage the seal face. Insure that the
stationary seat is fully seated into the seal housing. With a clean, lint
free cloth, wipe the seal face clean of all lubricant or debris.
15. With a new O-ring, install the seal housing onto the pump shaft,
seating the plate fully and squarely onto the pump outer shell.
16. Place the motor adapter over the 4 tie rod bolts, using an adequately
sized crane when required, and install the 4 lock washers and tie rod
nuts. Torque the nuts, in sequence, to the value provided in the
"ENGINEERING DATA" section of this manual.
17. With an adequately sized crane, carefully lower the motor onto the
motor adapter, lining up the electrical conduit connection and the 4
motor adapter bolt holes, as required.
