TT Twin-Screw Pump -
Installation, Operation & Maintenance Manual
•
If the pump or motor is damaged or leaking, electric shock, fire, explosion, toxic release,
physical harm, or environmental damage may result. Do not operate the unit until the
problem has been corrected or repaired.
•
Risk of serious personal injury or property damage. Dry running may cause rotating parts
within the pump to seize to non-moving parts. Do not run dry unless the pump is
specifically supplied to support a dry run condition.
•
Risk of death, serious personal injury, and property damage. Heat and pressure buildup
can cause explosion, rupture, and discharge of the pumped fluid. Never operate the pump
with discharge and/or suction valves closed.
•
Running a pump without safety devices exposes operators to risk of serious personal
injury or death. Never operate a unit unless appropriate safety devices (pressure relief
valves, guards, etc.) are properly installed. See specific information about safety devices
in other sections of this manual.
CAUTION:
Risk of injury and/or property damage. Operating a pump in an inappropriate application can
cause over pressurization, overheating, and/or unstable operation. Do not change the service
application without the approval of an authorized CIRCOR representative.
