For example, at 37°C (98°F), the dispensing rate will be 12% faster.
Similarly, at 9°C (48°F), the dispensing rate will be 8% slower. Installationat
high or low temperature may require selection of a slower or faster dispensing
rate to help compensate.
3.3 Shaft Diameter Effect
The rate of dispensing will need to be increased for large equipment shaft
diameters and can be decreased for small equipment shaft diameters
because of the change in mechanical seal face surface area. For every
change in shaft diameter of 50 mm (2 inch) above or below 100 mm
(4 inch), the discharge rate should be increased or decreased by an additional
3%. For example, a piece of equipment having a shaft diameter of 200 mm
(8 inch), the dispensing rate should be 6% faster. Similarly, for a piece of
equipment having a shaft diameter of 50 mm (2 inch), the dispensing rate can
be 3% slower. Installation for larger or smaller shaft diameters may require
selection of a faster or slower dispensing rate to help compensate and provide
adequate protection from damage to seal faces.
Please contact your Flowserve Sales and Service Representative or Authorized
Distributor for applications at extreme elevations above 3050 meters (10,000 feet)
or atmospheric temperatures above 55°C (130°F) or below -20°C (-4°F) and for
equipment shaft diameters larger than 250 mm (10 inch).
4 Maintenance
The Flowserve SLD Seal Support System components are relatively maintenance
free. Check frequently to be sure that the synthetic lubricant is being expelled by
observing the end of the stand pipe connected to the OUTLET quench chamber
connection and also take notice that the SLD auto-luber is becoming empty.
When the SLD auto-luber is empty, replace with a new one. Never try to refill
the SLD auto-luber or inject lubricant into the grease fitting by means of the
grease gun while the auto-luber is installed. There are no user replaceable or
serviceable components located inside of the SLD auto-luber unit itself.
Blip Light Indicators
Flashing Green Light: The system is purging. This means the SLD auto-luber is
functioning but lubricant is not yet being delivered beyond the end of the canister.
Flashing Red Light: The system is functioning normally. The lubricant is now
exiting the SLD auto-luber and is pressurized properly, supplying lubricant at the
current setting.
Steady Red Light: The system battery is dead and the SLD auto-luber is no longer
pressurizing. The SLD auto-luber should be replaced immediately.
No Light: The system is off, or battery is completely dead (if the system switches
are in the “on” position). If the battery is dead, the unit must be replaced.
Steady Red and Green Light: There is a system error. There is an electrical error
in the SLD auto-luber and the unit needs to be replaced.
Note: An empty SLD auto-luber might still have a flashing red light. There is no light
pattern that indicates that the SLD auto-luber is empty. Level must be checked by
a periodic visual inspection on the side of the canister.
