SL-5000 and SL-5200 Cartridge Seals are complete preset seal assemblies which include the sleeve
and gland. No seal settings or measurements are required. They are especially suitable for pumps
and rotating equipment handling abrasive slurries. The SL-5000 is a single seal design and the
SL-5200 is a dual seal.

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 operating 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.
Operational Recommendations

SL-5000
3.1
Do not start the equipment dry. Never start up the equipment without properly venting the
pump of air.
3.2
If the seal runs hot, check for proper seal setting, seal housing dimensions, and check the flush
lines for obstructions. Do not allow the equipment to run for any extended time if the seal gets
hot or squeals.
