DANGER
PERSONNEL INJURY DUE TO PROJECTILES
The following items may cause catastrophic pump failure resulting in projectiles. The
guarding is only designed to prevent personnel contact with the shaft and may not stop
projectiles. Do not stand in the line-of-fire.
• Improperly tightened couplings and coupling fasteners. Always ensure proper shaft
coupling installation prior to starting equipment.
• Incorrect driver rotational direction may unscrew coupling or damage pump. Always
ensure correct driver rotational direction with the pump uncoupled.
• Starting pump while it is spinning backwards. Never start a pump while it is spinning
backwards. A non-reverse ratchet on the driver or special system design must be utilized
to protect against this scenario.
• Reverse runaway rotation. For pumps not equipped with a non-reverse ratchet, the
system shall be designed and controlled such that the pump unit does not exceed the
specified maximum reverse runaway speed for that particular application. This capability
is not typically offered on pump units and must be specified by the customer in their pump
specification. If a maximum reverse runaway speed is not specified on the pump’s
Certified Outline Drawing, the operator must assume the unit was not designed for
reverse rotation.
• Improperly adjusted impellers could cause the pump to seize and catastrophically fail.
Always confirm that the impellers are properly adjusted.
• Overheating of the thrust bearing due to overload, over-speed, poor lubrication, poor
cooling or damage may result in seizing of the thrust bearing. Always ensure proper
operation of the thrust bearing.
WARNING
SERIOUS PERSONAL INJURY AND EQUIPMENT DAMAGE
• Pump units must only be used for their intended purpose. Refer to the certified outline
drawing and other contract documents for construction and application details.
• The pumps must not be operated beyond their design MAWPs (suction and discharge
sides), temperature limits and speed limits specified for the application. These limits are
dependent on the pump type, configuration and materials used. If there is any doubt
about the suitability of the product for the intended application, contact Trillium Pumps
USA, referencing the serial number.
WARNING
PERSONNEL INJURY FROM HAZARDOUS PUMPAGE
• Prior to introducing hazardous pumpage to any system, always leak test the system and
check for loose fitting and acceptable sealing.
• For applications involving hazardous fluids, degradation of the equipment and resulting
leaks may occur over time due to normal corrosion and wear of containment vessels and/
or sealing components. Procedures must be utilized to inspect equipment in such
applications to detect problems before they cause hazardous leaks and to detect leaks if
they occur.
