Commissioning, Startup, Operation, and
Shutdown

Preparation for startup

WARNING:
• Risk of serious physical injury or death. Exceeding any of the pump operating limits (e.g. -
pressure, temperature, power, etc.) could result in equipment failure, such as explosion,
seizure, or breach of containment. Assure that the system operating conditions are within
the capabilities of the pump.
• Risk of death or serious injury. Leaking fluid can cause fire and/or burns. Ensure all
openings are sealed prior to filling the pump.
• Breach of containment can cause fire, burns, and other serious injury. Failure to follow
these precautions before starting the unit may lead to dangerous operating conditions,
equipment failure, and breach of containment.
• Risk of serious personal injury or property damage. Dry running may cause rotating parts
within the pump to seize to non-moving parts. Do not run dry.
• Risk of explosion and serious physical injury. Do not operate pump with blocked system
piping or with suction or discharge valves closed. This can result in rapid heating and
vaporization of pumpage.
• Risk of breach of containment and equipment damage. Ensure the pump operates only
between minimum and maximum rated flows. Operation outside of these limits can cause
high vibration, mechanical seal and/or shaft failure, and/or loss of prime.
• Avoid mechanical seal failure or pump seizure by:
• increasing speed at startup to at least 65% of rated speed within 5 seconds and
• decreasing speed at shutdown from 65% of rated speed to 0 within 5 seconds
• Foreign objects in the pumped liquid or piping system can block the flow and cause excess
heat generation, sparks and premature failure. Make sure that the pump and systems are
free of foreign objects before and during operation.
•
result in an explosive environment. Make sure the process piping system, pump and
sealing system are properly vented prior to operation.
•
manual venting prior to operation. Failure to do so will result in excess heat generation and
seal failure.
• Running a pump without safety devices exposes operators to risk of serious personal
injury or death. Never operate a unit unless appropriate safety devices (guards, etc.) are
properly installed.
• Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any
installation or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
• Refer to driver/coupling/gear manufacturer's installation and operation manuals (IOM)
• Starting the pump in reverse rotation can result in the contact of metal parts, heat
generation, and breach of containment. Ensure correct driver settings prior to starting any
pump.
• Risk of seizure, breach of containment, or explosion. Ensure balance line is installed and
piped back to either the pump suction or suction vessel. This prevents rapid vaporization of
the pumped fluid.
