John crane 5611 Instruction manual

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 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.

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.

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.

WARNING: Seal installation should be handled only by

qualified personnel. If questions arise, contact the

local John Crane Sales/Service Engineer. 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. lease contact the company for

information as to exclusive product warranty and

limitations of liability.

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 the seal most efficiently.

Refers to special information or instructions directed

towards the prevention of damage to the seal or its

surroundings.

Refers to mandatory instructions designed to prevent

personal injury or extensive damage to the seal or its

surroundings.

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.

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 ohn 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 750˚F/400˚C, they can decompose.

Therefore, 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.

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.

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.

If the seal is to be used for an application other than that originally intended or

outside the recommended performance limits, ohn Crane must be contacted

before its installation and use.

Any warranty may be affected by improper handling, installation, or use of this

seal. Contact the Company for information as to exclusive product warranty

and limitations of liability.

If questions or problems arise, contact your local ohn Crane Sales/Service

Engineer or the original equipment manufacturer, as appropriate.

ohn 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.

6. Set the gland plate assembly gasket side down on table. Install collar on

gland plate assembly and engage spacers into groove, aligning spacers

with pipe taps of gland plate. Uniformly finger tighten the cap screws.

This sets the radial spacing of the cartridge.

7. Install disc into the retainer, rotating the disc slightly to secure it in place.

8. Install drive band, ears first, into the notches in the back of the retainer.

The leg of the drive band without ears should be facing away from the

retainer.

9. Turn the bellows inside-out and place it with the retainer/drive band/disc

assembly.

10. Turn the bellows right-side-out, folding the bellows into the lip of the drive

band and completely around the disc. Gently pull on the bellows to

ensure it is properly seated. The disc should not be visible once this step

is completed.

11. Install the primary ring, lapped face up, into the retainer assembly so the

un-lapped face rests against the front flange of the bellows.

12. Lightly lubricate the ID of the bellows. Lightly lubricate the OD of the

entire sleeve for best results.

13. With the sleeve standing on its base, first install the spring, then the

spring adapter. The flat side of the spring adapter should rest on top of

the spring. The adapter should not enclose the spring.

14. Carefully slide the seal head assembly onto the sleeve, ensuring the tail

of the bellows remains flat. Should the bellows roll under, remove the seal

head from the sleeve and restart this step, gently turning the seal head.

Once the seal head assembly is correctly positioned, gently slide it back

and forth once to ensure its mobility.

15. Clean faces of primary and mating rings with denatured alcohol and a

lint-free cloth.

16. With the entire assembly still standing on the sleeve base, carefully lower

the gland plate assembly over the sleeve assembly until the seal faces

touch. Carefully rotate the faces against each other one or two turns.

17. Align set screws in collar with through holes in end of sleeve.

18. Install snap ring over the end of sleeve. This sets the axial spacing of

the cartridge. Do no overcompress gland pla e or his may damage

he seal.

19. Tighten set screws until they start to enter the sleeve ID.

20. Uniformly tighten cap screws on spacers.

21. Install gasket and sleeve O-Ring.

22. Pressure test according to ohn Crane standard QA-5-0568.

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.

4. Make sure that gland plate gasket (Type 5611) is properly positioned,

and that collar set screws do not extend past sleeve ID. Slide complete

cartridge seal assembly onto shaft. Position gland plate so pipe con-

nection #1 is at or near top dead center for ANSI pumps. 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 applica-

ble) 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 secure (1/4 turns, 180˚ apart), with gland plate (Type 5611) and

face of pump seal chamber metal-to-metal. Do not over-stress 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.

Decommissioning the Equipment

1. Ensure that the pump is electrically isolated.

If the equipment has been used on toxic or hazardous fluids,

ensure that the equipment is correctly decontaminated and

made safe prior to commencing work. Remember fluid is often

trapped during draining and may exist outside the seal. The

pump instruction manual should be consulted to check for any

special precautions.

2. Ensure that the pump is isolated by the appropriate valves.

Check that the fluid is drained and pressure is fully released.

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 ohn Crane Seal

Rebuilding Center, 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 ohn 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 ohn Crane publication.

I-5611/5611Q - 5 -

Installing the Seal (cont.)

It is recommended that the seal cavity be vented through the pump’s lantern

ring connection located at top dead center. It is always recommended that a

flush injection be utilized. the flush should be piped into the seal gland to

ensure maximum efficiency.

For DIN pumps rotate gland 135˚ CCW. Use port #2 as flush.

NOTE: For CCW (counter clockwise) rotation pumps, consult ohn Crane

Engineering.
