NOTICE:
•
Verify the driver settings before you start any pump. Refer to the applicable drive
equipment IOMs and operating procedures.
•
Excessive warm-up rates can cause equipment damage. Ensure the warm-up rate
does not exceed 1.4°C | 2.5°F per minute.
•
The mechanical seal used in an Ex-classified environment must be properly certified.
NOTICE:
You must follow these precautions before you start the pump:
•
Flush and clean the system thoroughly to remove dirt or debris in the pipe system in
order to prevent premature failure at initial startup.
•
Bring variable-speed drivers to the rated speed as quickly as possible.
•
Run a new or rebuilt pump at a speed that provides enough flow to flush and cool the
close-running surfaces of the stuffing-box bushing.
•
If temperatures of the pumped fluid will exceed 93°C | 200°F, then warm up the pump
prior to operation. Circulate a small amount of fluid through the pump until the casing
temperature is within 38°C | 100°F of the fluid temperature. Accomplish this by flowing
fluid from pump inlet to discharge drain (optionally, the casing vent can be included in
warm-up circuit but not required). Soak for (2) hours at process fluid temperature.
At initial startup, do not adjust the variable-speed drivers or check for speed governor or over-speed
trip settings while the variable-speed driver is coupled to the pump. If the settings have not been veri-
fied, then uncouple the unit and refer to instructions supplied by the driver manufacturer.
