5 Commissioning, Startup, Operation, and
Shutdown
5.1 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 open-
ings 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 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 va-
porization 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.
WARNING:
•
Foreign objects in the pumped liquid or piping system can block the flow and cause ex-
cess heat generation, sparks and premature failure. Make sure that the pump and sys-
tems are free of foreign objects before and during operation.
•
If the pump does not prime properly, or loses prime during start-up, it should be shutdown
and the condition corrected before the procedure is repeated.
•
A build-up of gases within the pump, sealing system, or process piping system may
result in an explosive environment. Make sure the process piping system, pump and seal-
ing system are properly vented prior to operation.
•
Sealing systems that are not self-purging or self-venting, such as plan 23, require
manual venting prior to operation. Failure to do so will result in excess heat generation
and seal failure.
•
Risk of death, serious personal injury, and property damage. Heat and pressure buildup
can cause explosion, rupture, and discharge of pumpage. Never operate the pump with
suction and/or discharge valves closed.
•
Running a pump without safety devices exposes operators to risk of serious personal in-
jury 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 installa-
tion or maintenance tasks.
•
Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
