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.
• Do not operate pump below hydraulic or thermal minimum flow. For hydraulic minimum
flows refer to technical manual and pump performance curve. To calculate thermal
minimum flow, refer to HI Centrifugal Pumps for Design and Application ANSI/HI 1.3-2000.
• 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.
Also ensure the pump operates above the thermal minimum flow. To calculate the thermal
minimum flow, refer to Hydraulic Institute 1.3-2013.
• 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
WARNING:
• 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
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals (IOM)
for specific instructions and recommendations.
• 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.
Precautions
NOTICE:
• Verify the driver settings before you start any pump.
• When a cartridge mechanical seal is used, ensure that the set screws in the seal locking
ring are tightened and that the centering clips have been removed prior to startup. This
prevents seal or shaft sleeve damage by ensuring that the seal is properly installed and
centered on the sleeve.
You must follow these precautions before you start the pump:
