6.3 Thrust pot lubrication guidelines
Flushing the oil reservoir
Flush the oil reservoir in order to remove all grit particles in the oil reservoir sump. Use the same type of
oil to flush the reservoir as specified for lubrication.
NOTICE:
•
Pumps are shipped without oil. Oil-lubricated bearings must be lubricated at the job site.
•
Refer to Thrust Pot IOM for lubrication requirements.
Oil levels
Pump status Oil level
Not operating At or lower than 0.635 to 0.3175 mm | 1/8 in. to 1/4 in. from the top of the oil sight gauge. Never
operate the pump when the oil in the sight gauge is not at the required level.
Changing the oil
Observe the instructions in the Thrust Pot IOM.
6.4 Disassembly
6.4.1 Disassembly precautions
WARNING:
•
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.
•
Risk of serious personal injury. Applying heat to impellers, propellers, or their retaining
devices can cause trapped liquid to rapidly expand and result in a violent explosion. This
manual clearly identifies accepted methods for disassembling units. These methods must
be adhered to. Never apply heat to aid in their removal unless explicitly stated in this
manual.
•
Handling heavy equipment poses a crush hazard. Use caution during handling and wear
appropriate Personal Protective Equipment (PPE, such as steel-toed shoes, gloves, etc.)
at all times.
•
Precautions must be taken to prevent physical injury. The pump may handle hazardous
and/or toxic fluids. Proper personal protective equipment should be worn. Pumpage must
be handled and disposed of in conformance with applicable environmental regulations.
•
Risk of serious physical injury or death from rapid depressurization. Ensure pump is iso-
lated from system and pressure is relieved before disassembling pump, removing plugs,
opening vent or drain valves, or disconnecting piping.
•
Risk of serious personal injury from exposure to hazardous or toxic liquids. A small
amount of liquid will be present in certain areas like the seal chamber upon disassembly.
