5 Maintenance
5.1 Maintenance
5.1.1 Maintenance - O-ring, pump flange to slide rail base flange
Whenever the pump is removed from the sump using the slide rail system, the pump flange to slide rail
base flange O-ring should be inspected for wear. If it does not appear to be in good condition, a replace-
ment O-ring should be installed after the groove has been cleaned and dried so the adhesive will bond to
the metal and rubber.
NOTICE:
Cleaning the guide bracket around the hinge pin 9868 will help ensure proper operation when
the pump is lowered back into place.
5.2 Disassembly
5.2.1 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.
