Goulds Pumps 3996 - IOM - Manual (Page 28)

START-UP PRECAUTIONS
1. All equipment and personal safety related devices and
controls must be installed and operating properly.
2. To prevent premature pump failure at initial start-up
due to dirt or debris in the pipe system, ensure the
pump can be run continuously at full speed and flow
for 2 to 3 hours.
3. Variable speed drivers should be brought to rated
speed as quickly as possible.
4. Variable speed drivers should not be adjusted or
checked for speed governor or overspeed trip settings
while coupled to the pump at initial start-up. If
settings have not been verified, uncouple the unit and
refer to driver manufacturer’s instructions for
assistance.
5. Pumpage temperatures in excess of 93° C (200° F) will
require warm-up of pump prior to operation. Circulate a
small amount of pumpage through the pump until the
casing temperature is within 38° C (100° F) of the
pumpage temperature and evenly heated.
NOTE: Warm-up rate should not exceed 1.4° C
(2.5° F) per minute.
