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:
•
Failure to use or incorrect use of auxiliary connections provided (e.g. barrier fluid, flushing
liquid, etc.) may result in injury from escaping fluid, burns, and malfunction of the pump.
Refer to the general arrangement drawing, piping layout, mechanical seal drawing and
seal system drawing for the quantity, dimensions and locations of auxiliary connections.
•
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.
•
Prior to startup, make sure that all areas, such as threaded openings, vent and drain
valves, and flanged openings, that could leak pumped fluid to the work environment are
closed.
•
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.
•
Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
