Maintenance

Mechanical seal life

The life of a mechanical seal depends on the cleanliness of the pumped fluid. Due to the
diversity of operating conditions, it is not possible to give definite indications as to the life of a
mechanical seal.

Disassembly

Disassembly precautions

WARNING:

•

This manual clearly identifies accepted methods for disassembling units. These methods must

be adhered to. Trapped liquid can rapidly expand and result in a violent explosion and injury. Never
apply heat to impellers, propellers, or their retaining devices to aid in their removal unless explicitly
stated in this manual.

•

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.

• Crush hazard. The unit and the components can be heavy. Use proper lifting methods and wear

steel-toed shoes at all times.

• 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.

• A small amount of liquid will be present in certain areas like the seal chamber.

NOTICE:

• Avoid injury. Worn pump components can have sharp edges. Wear appropriate gloves

while handling these parts.

• Make sure that all replacement parts are available before you disassemble the pump for

overhaul.

Tools required

In order to disassemble the pump, you need these tools:

• Brass drift punch

• Cleaning agents and solvents

• Dial indicators

• Drill

• Feeler gauges

• Hex wrenches

• Induction heater

• Lifting sling

• Micrometers (inside and outside)

• Open end wrenches

• Press

• Soft face hammer

• Spanner wrench

• Spanning type puller
