6.5.8 Pump disassembly for pumps with integrated stuffing box design
The disassembly process for pumps with an integrated stuffing box may be considered
identical to the drop-in stuffing box design with a few minor differences. Please note
differences outlined below and then refer to Pump disassembly for pumps with drop-in
stuffing box and sleeve over shaft (dry shaft) design on page 50 and Pump disassembly for
pumps with drop-in stuffing box and sleeveless shaft (wet shaft) design on page 61. Follow
all safety procedures outlined in Pump disassembly on page 50.
1. Before separating the upper and lower casing, remove both pump shaft guards, all
flush lines, and remove the top two seal gland bolts from the upper casing on both
sides of the pump.
Note: For packing configurations, the flush line ports run through the upper casing just
above the seal chamber.
