5 Commissioning, Startup,
Operation, and Shutdown

5.1 Preparation for startup

WARNING:
• Failure to follow these precautions before you start the unit will lead to serious personal
injury and equipment failure.
• Do not operate the pump below the minimum rated flows or with the suction or discharge
valves closed. These conditions can create an explosive hazard due to vaporization of
pumped fluid and can quickly lead to pump failure and physical injury.
• If the pump, motor, or piping operate at extremely high or low temperatures, then
guarding or insulation is required. Failure to follow these instructions can result in serious
personal injury or death, and property damage.
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious
physical injury.
• Operating the pump in reverse rotation can result in the contact of metal parts, heat
generation, and breach of containment.
NOTICE:
• Make sure that the warm-up rate does not exceed 2.5°F (1.4°C) per minute.
You must follow these precautions before you start the pump:
• Flush and clear the system thoroughly to remove dirt or debris in the pipe system in order
to prevent premature failure at initial startup.
• Run a new or rebuilt pump at a speed that provides enough flow to flush and cool the
close-running surfaces of the stuffing-box bushing.
• If temperatures of the pumped fluid will exceed 200°F (93°C), then warm up the pump
prior to operation. Circulate a small amount of fluid through the pump until the casing
temperature is within 100°F (38°C) of the fluid temperature.

5.1.1 Check the rotation

WARNING:
• Operating the pump in reverse rotation can result in the contact of metal parts, heat
generation, and breach of containment.
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious
physical injury.
1. Unlock power to the driver.
2. Make sure that everyone is clear, and then jog the driver long enough to determine that
the direction of rotation corresponds to the arrow on the pump.
3. Lock out power to the driver.
