Precautions
Warning: do not operate units without safety guards in place or severe personal injury
may result.
Warning: Splashing or immersing open drip proof motors in fluid can cause fire, shock,
burns or death. Make sure motor guards are in place.
Warning: Operation at or near zero flow can cause extreme heat, personal injury or
property damage.
Starting
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.
Caution: Immediately observe pressure gauges. If discharge pressure is not quickly
attained, stop driver, re-prime and attempt to restart.
4. Slowly open discharge valve until the desired flow is obtained.
Caution: Observe pump for vibration levels, bearing temperature and excessive noise. If
normal levels are exceeded, shut down and resolve.
5. After stabilizing the system at normal operating conditions, check the piping and
adjust supports if needed.
Operation
General considerations:
Caution: Always vary capacity with regulating valve in the discharge line. Never
throttle flow from the suction side.
Caution: Driver may overload if the pumpage specific gravity (density) or viscosity is
greater than originally assumed or the rated flow rate is exceeded.
Caution: Always operate the pump at or near the rated conditions to prevent damage
resulting from cavitation or recirculation.
