2.3 Position the P-200 cartridge gland with the gland gasket in place
against the pump back plate (seal chamber/stuffing box) face,
install flat washers on the studs to prevent misalignment, and
tighten the gland nuts evenly, cross-staggering the adjustment
of the nuts. Do not over tighten.
2.4 Assemble the pump, adjust the bearings, set the impeller
and connect the coupling so that the shaft is in its operating
axial position. Any subsequent axial adjustment of the shaft
requires resetting of the seal. Connect pump piping,
(see Section 3) allowing no pipe strain on the pump casing.
2.5 Tighten the set screws on the P-200 cartridge collar with the Allen
wrench provided.
2.6 Remove setting devices by removing the cap screws with the
Allen wrench provided. Save the setting devices for use if pump
impeller must be reset or if the P-200 is removed for maintenance.
2.7 Turn the shaft by hand to ensure free operation.
2.8 Pipe up the gland connections to the P-200 seal as explained in
Section 3.
2.9 See Operational Recommendations, Section 4, before starting
pump.
