HINWEIS:
Warm-up rate should not exceed 1.4° C (2.5° F) per minute.
4.3 Starting Pump
1.
Make sure suction valve and any recirculation or cooling lines are open.
2.
Fully close or partially open discharge valve as dictated by system conditions.
3.
Start Driver.
HINWEIS:
Immediately observe pressure gauges. If discharge pressure is not quickly at-
tained - stop driver, reprime and attempt to restart.
4.
Slowly open discharge valve until the desired flow is obtained.
HINWEIS:
Observe pump for vibration levels, bearing temperature and excessive noise. If
normal levels are exceeded, shut down and resolve.
4.4 Operation
4.4.1 General Considerations
HINWEIS:
Always vary capacity with regulating valve in the discharge line. NEVER throttle
flow from the suction side.
HINWEIS:
Driver may overload if the pumpage specific gravity (density) is greater than
originally assumed, or the rated flow rate is exceeded.
HINWEIS:
Always operate the pump at or near the rated conditions to prevent damage re-
sulting from cavitation or recirculation.
