DUAL O-RING CARTRIDGE SEAL

Installation, Operation & Maintenance Instructions

PAGE

Foreword

These instructions are provided to familiarize the user with the seal and its designated use. The instructions must be read and applied whenever work is done on the seal, and must be kept available for future reference.

Safety Instructions

1. The following designations are used in the installation instructions to highlight instructions of particular importance.

NOTE: Refers to special information on how to install or operate

Refers to special information or instructions directed

Refers to mandatory instructions designed to

2. Installation, removal and maintenance of the seal must be carried out only by qualified personnel who have read and understood these installation instructions.

3. The seal is designed exclusively for sealing rotating shafts. The manufacturer cannot be held liable for use of the seal for purposes other than this.

4. The seal must only be used in technically perfect condition, and must be operated within the recommended performance limits in accordance with its designated use set out in these installation instructions.

towards the prevention of damage to the seal or its surroundings.

prevent personal injury or extensive damage to the seal or its surroundings.

ATTENTION

If the seal is to be used for an application other than that originally intended or outside the recommended performance limits, John Crane must be contacted before its installation and use.

Any warranty may be affected by improper handling, installation, or use of this seal. Contact John Crane for information as to exclusive product warranty and limitations of liability.

If questions or problems arise, contact your local John Crane representative or the original equipment manufacturer, as appropriate.

ATTENTION

5. If the pumped fluid is hazardous or toxic, appropriate precautions

must be taken to ensure that any seal leakage is adequately contained. Further information on sealing hazardous or toxic fluids should be obtained from John Crane prior to seal installation.

6. Fluorocarbon components should never be burned or incinerated as the fumes and residues are highly toxic. If fluorocarbons are accidentally heated above 400˚C/750˚F, they can decompose. Protective gloves should be worn as hydrofluoric acid may be present.

7. PTFE components should never be burned or incinerated as the fumes are highly toxic.

These instructions are for the installation and operation of a seal as used in rotating equipment and will help to avoid danger and increase reliability. The information required may change with other types of equipment or installation arrangements. These instructions must be read in conjunction with the instruction manuals for both the pump and any ancillary equipment.

John Crane mechanical seals are precision products and must be handled appropriately. Take particular care to avoid damage to lapped sealing faces and to flexible sealing rings. Do not excessively compress the seal before or during installation.

Before Starting the Equipment

1. Check the pump at the coupling for proper alignment of the driver or motor.

2. Ensure that the gland plate nuts/bolts are securely tightened according to the pump manual instructions, and that all screws are securely fastened.

3. Complete the assembly of the pump, and turn the shaft (by hand if possible) to ensure free rotation.

4. Consult all available equipment operating instructions to check for correctness of all piping and connections, particularly regarding seal recirculation/flush, heating or cooling requirements, and services external to the seal.

This mechanical seal is designed to operate in a liquid so

ATTENTION

5. Check that the seal chamber fluid lines are open and free of any obstruction, and ensure that the seal chamber is properly vented and filled with liquid - refer to the pump instruction manual.

the heat energy it creates is adequately removed. Therefore, the following check should be carried out not only after seal installation, but also after any period of equipment inactivity.

ATTENTION

WARNING: Seal installation should be handled only by qualified

Dry-running - often indicated by a squealing noise from the seal area - will cause overheating and scoring or other damage to the sealing surfaces, resulting in excessive leakage or a much shortened seal life.

Before start-up, ensure that all personnel and assembly equipment have been moved to a safe distance so there is no contact with rotating parts on the pump, seal, coupling, or motor.

personnel. If questions arise, contact the local John Crane representative. Improper use and/or installation of this product could result in injury to the person and/or harmful emissions to the environment, and may affect any warranty on the product. Please contact the company for information as to exclusive product warranty and limitations of liability.

Installing the Seal

1. Before starting the installation, read the following instructions carefully.

2. Remove the seal from its packaging, inspect for any damage, and wipe clean.

3. The equipment should be clean and meet the specifications noted in the “Preparing the Equipment” section. Lubricate sleeve O-ring with lubricant recommended in chart below. Lubricate shaft sparingly. Lubricate gland plate bolts/nuts as required.

ELASTOMER LUBRICANT

Fluoroelastomer Vegetable Oil, Animal Oil, Mineral-Hydrocarbon Oils, (i.e. Viton™) Soap Solution, Parker ‘Super-O-Lube’, Silicone Grease

Ethylene Propylene Vegetable Oil, Polywater™, Soap Solution, Glycerine, Propylene Glycol, Silicone Grease

Perfluoroelastomer Vegetable Oil, Animal Oil, Mineral-Hydrocarbon Oils (i.e. Kalrez™)

OTE: Always use a lubricant that is compatible with your machinery and product.

Use lubricant sparingly, only enough to install seal with ease.

Installation, Operation & Maintenance Instructions

4. Make sure that gland adapter gasket is properly positioned, and that collar set screws do not extend past sleeve ID. Slide complete cartridge seal assembly onto shaft. For ANSI pumps position gland plate so pipe connection #1 is at or near top dead center. For DIN pumps, position gland plate so slot between pipe connections #3 and #4 is at or near top dead center. Slide cartridge onto studs (if applicable) until gasket is flush against the face of seal chamber. Hand tighten gland plate bolts/nuts.

5. Reassemble pump and make all necessary impeller adjustments.

6. Continue tightening gland plate bolts/nuts in an alternating pattern until gland plate is secure (1/4 turns, 180˚ apart). Do not overstress or distort gland plate.

7. Tighten collar set screws evenly (1/4 turns, 180˚ apart), securing cartridge seal to shaft.

8. Remove spacers and save.

9. Make appropriate piping connections to seal assembly.

Maintenance

No maintenance of a seal is possible while installed. Therefore, it is recommended that a spare seal unit be held in stock to allow immediate replacement of a removed seal.

It is recommended that used seals are returned to a John Crane service location, as rebuilding to as-new specifications must be carried out by qualified personnel.

It is the responsibility of the equipment user to ensure that any parts being sent to a third party have appropriate safe

handling instructions externally attached to the package.

Quality Assurance

This seal has been assembled in accordance with John Crane quality assurance standards and with proper maintenance and use will give safe and reliable operation to the maximum recommended performance as shown in any relevant approved John Crane publication.
