1.5 Check assembly drawing included with the seal for specific
seal design, materials of construction, dimensions, and piping
connections.
1.6 Check shaft or sleeve OD seal chamber bore, seal chamber
depth, and distance to the first obstruction to ensure that
they are dimensionally the same as shown on the seal assembly
drawing.
1.7 Check gland pilot and bolt holes to ensure they are adaptable
to the equipment and are the same as shown on the assembly
drawing.
1.8 Handle all seal parts with care, they are manufactured to precise
tolerances. The seal faces on the rotating and stationary faces are
of special importance. These two sealing faces are lapped flat to
within three light bands (34.8 millionths of an inch). Keep the seal
faces perfectly clean at all times.
2 Installation
2.1 Lubricate the shaft lightly with silicone lubricant before installing
the seal assembly on the shaft.
2.2 Install the complete cartridge seal assembly over the shaft and
ease it into position. Care should be exercised when passing the
sleeve incorporating the O-ring over any keyways or threads that
may be present. Any steps or shoulders on the shaft should be
beveled to prevent damage (pinching and cutting) of the O-ring
sleeve gasket during installation. Attach the gland bolts loosely,
hand tight, to the face of the seal chamber.
2.3 After the pump assembly has been completed with the impeller,
shaft, coupling, and bearing in their respective running or operat-
ing position, tighten the gland bolts to the seal chamber, evenly
cross staggering the adjustment of the bolts.
2.4 Be sure the set screw material is harder than the shaft material to
bite into the shaft and hold the required load. Tighten the sleeve
collar set screws to the shaft by cross staggering the adjustment.
2.5 Remove the setting devices from between the sleeve drive collar
and gland, and store for future use.
2.6 The seal is set and ready for operation.
