Goulds Pumps 3296 EZMAG - IOM - Manual (Page 49)

Commissioning, Startup, Operation, and Shutdown
CAUTION:
• The pump and system must be free of foreign objects. If pump becomes plugged, shut down and
unplug prior to restarting pump.
• Avoid excessive vibration levels. Excessive vibration levels can damage the bearings, stuffing box
or seal chamber, and the mechanical seal, which can result in decreased performance.
• Avoid increased radial load. Failure to do so can cause stress on the shaft and bearings.
• Avoid heat build-up. Failure to do so can cause rotating parts to score or seize.
• Avoid cavitation. Failure to do so can cause damage to the internal surfaces of the pump.
Operation under freezing conditions
NOTICE:
Do not expose an idle pump to freezing conditions. Drain all liquid that is inside the pump and
the cooling coils. Failure to do so can cause liquid to freeze and damage the pump.
Temperature ratings
CAUTION:
Do not operate the pump above the rated temperature range of the magnets. This will weaken or ruin the
magnets. The rated temperature is 250°F (121°C) for all sizes.
Magnetic types Drive destination Rated temperature
Neodymium iron (NdFe) A, B, C, D, E, F, G, H, I, J, K 356°F (180°C)
Samarium Cobalt (SmCo) AA, BB, CC, DD, EE, FF, GG, HH, 536°F (280°C)
II, JJ, KK
Shut down the pump
WARNING:
The pump can handle hazardous and toxic fluids. Identify the contents of the pump and observe proper
decontamination procedures in order to eliminate the possible exposure to any hazardous or toxic fluids.
Wear the proper personal protective equipment. Potential hazards include, but are not limited to, high
temperature, flammable, acidic, caustic, explosive, and other risks. You must handle and dispose of
pumped fluid in compliance with the applicable environmental regulations.
1. Slowly close the discharge valve.
2. Shut down and lock the driver to prevent accidental rotation.
Make the final alignment of the pump and driver
WARNING:
• 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.
• Electrical connections must be made by certified electricians in compliance with all international,
national, state, and local rules.
• Refer to driver/coupling/gear manufacturers installation and operation manuals (IOM) for specific
instructions and recommendations.
• Follow shaft alignment procedures in order to prevent catastrophic failure of drive components or
unintended contact of rotating parts. Follow the coupling installation and operation procedures from
the coupling manufacturer.
You must check the final alignment after the pump and driver are at operating temperature. For
initial alignment instructions, see the Installation chapter.
