Experience In Motion

1. Drawing, Brief Description, Explosion Protection, Functional Requirements

This mechanical seal is designed to provide reliable performance under a wide range of operating conditions. The information and specifications presented in this product brochure are believed to be accurate, but are supplied for information purposes only and should not be considered certified or as a guarantee of satisfactory results by reliance thereon. Nothing contained herein is to be construed as a warranty or guarantee, express or implied, with respect to the product.

Although Flowserve Corporation can provide general application

guidelines, it cannot provide specific information for all possible applications. The purchaser/user must therefore assume the ultimate responsibility for the proper selection, installation, operation and maintenance of Flowserve products. Because Flowserve Corporation is continually improving and upgrading its product design, the specifications, dimensions and information contained herein are subject to change without notice.

1.1 Assembly Drawing

The assembly drawing is included in the shipping box with the

mechanical seal.

1.2 Brief Description

A mechanical seal is a device designed to seal a rotating shaft

against a stationary housing, e.g. a pump shaft against a pump casing. The stationary components will consist of a seal ring

This ISC seal is a cartridge mounted mechanical seal, designed for ease of installation and reliable operation. No seal setting dimensions are required. Removable centering tabs provide proper alignment.

The ISC seal family consists of: ISC1PX - Single Pusher Seal stationary springs ISC2PP - Dual Pusher Seal stationary springs ISC1BX - Single Metal Bellows Seal rotating bellows (standard) ISC2BB - Dual Metal Bellows Seal rotating bellows (standard) ISC1SX - Single Metal Bellows Seal stationary bellows (optional) ISC2SS - Dual Metal Bellows Seal stationary bellows (optional)

The flexible stator pusher design compensates for inadvertent misalignment of the seal chamber face. Multiple springs provide uniform face loading and are external of the process fluid, resisting clogging and stress corrosion.

The bellows design is available in both rotating and stationary bellows arrangements.

Rotating bellows arrangements are used when the self cleaning feature is required and stationary bellows are used to compensate for misalignment of the seal chamber face.

Installation according to the following steps will assure long trouble free life of the seal.

For applications which require information on expected surface

temperatures of the mechanical seal faces, Flowserve document “ATEX 137 information declaration” is available upon request. This document allows users to determine typical surface temperatures based upon seal design, operating conditions and face materials and may be used by the users to comply with ATEX 1999/92/EC (ATEX 137).

1.4 Functional requirements

The proper functioning of a mechanical seal is only achieved once

the following conditions have been met:

• The sealing surfaces are lapped within specification

• Perpendicularity and concentricity between the shaft and the

seal chamber face and bore respectively

• Freedom of movement of the spring loaded components in axial

direction

• Axial and radial shaft movements within Flowserve or OEM tole

rances whichever is the tightest.

•

The seal is run under the conditions for which it was selected.

• The equipment in which the seal(s) is (are) installed is run

within normal parameters (no cavitation, excess vibration etc.)

• Prevention of sedimentation on shaft or sleeve surfaces caused

by for instance crystallisation or polymerisation

• Permanent seal liquid film between the sealing surfaces

If these function conditions are not fulfilled, the consumption of product, for example, is increased and parts of the product can escape into the atmosphere. Other effects can include high component temperatures.

and (depending on the design) a spring-loaded element. The spring-loaded element can be a spring or a bellows. The seal ring is sealed against the housing with a secondary gasket, e.g. an O-ring. The rotating components will consist of a seal ring and (depending on the design) a spring-loaded element. The springloaded element can be a spring or a bellows. The seal ring is sealed against the shaft with a secondary gasket, e.g. an O-ring. A mechanical seal can be supplied as a pre-assembled cartridge or in separate components. Assembly is done in accordance with the assembly drawing. A mechanical seal will run in the pumped product or external source fluid.

To provide lubrication, a film of liquid must always be present

between the seal faces. The sealing surfaces are separated from each other by the seal liquid film during shaft rotation and in principle run without contact and thus minimal wear under these conditions.

1.3 Explosion Protection The ISC mechanical seal is a standard cartridge seal and as such

regarded as a machine element. Machine elements do not need to comply with Directive 94/9/EC (ATEX 95 product guide) as these are regarded as an integral part of a larger piece of machinery (pump, agitator). This has been confirmed by both the EC ATEX standing committee as well as the European Sealing Association (ESA).Reference is made to following web-sites:

EC ATEX standing committee:

http://ec.europa.eu/enterprise/atex/rotating.htm

ESA position statement:

http://www.europeansealing.com/statements.html

on people and/or the environment. Components coming into contact with leakage must be corrosion resistant or suitably protected.

EXPLOSION PROTECTION – This means that failure to observe these instructions will involve the risk of explosion in potentially explosive environments which can cause harm to persons and / or considerable damage to property.

Plant regulations concerning work safety, accident prevention and pollution must be strictly adhered to.

This mechanical seal has been designed and built to seal rotating equipment. Damages resulting from use in other applications are the responsibility of the user.

Failure, recovery or fluctuation in power supply to the machine and/or supply system may not expose persons or environment to dangerous situations or harm the functionality of the mechanical seal.

Guards that are provided by the equipment manufacturer have to be in accordance with plant regulations, but should not create additional danger. These guards have to ensure proper access to the working area required for maintenance to the mechanical seal.

The electricity supply of the equipment must be in accordance with directive 2006/95/EC. When machinery is powered by a source of energy other than electricity this may not cause dangerous situations for persons and environment.

See the directive 94/9/EC, 1999/92/EC and EN 13463-5.

Failure to meet these requirements will result in excessive leakage and/ or shortened seal life.

Safety

DANGER

: This means that personal danger or major material

damage can occur when no attention is paid to this.

ATTENTION

: This means that important information is pointed

out that may also be overlooked by skilled personnel. The information can be important to avoid personal injury or material damage.

Please read these instructions carefully. Installation in accordance with the following instructions will contribute to long and trouble free running of the mechanical seal.

For related mechanical seal auxiliary equipment (reservoirs, coolers, etc.), separate instructions will be provided.

The ultimate user must ensure that personnel assigned to handle, install and run the mechanical seal and related equipment is well acquainted with the design and operating requirements of such equipment.

For this personnel it may be required to wear protective clothing as per the plant’s safety regulations.

Damage to any of the seal components and in particular the faces may cause (excessive) leakage in liquid or gas form. The degree of hazard depends on the sealed product and may have an effect

3. General

All illustrations and details in these installation instructions are subject to changes that are necessary to improve product performance without prior notice.

The copyright of these instructions is the property of Flowserve. These instructions are intended for Maintenance, Operating and Supervisory personnel and contain regulations and drawings of a technical character that may not, in full or in part, be copied, distributed, used without authorisation for competitive purposes, or given to others.

It should be understood that Flowserve does not accept any liability for instances of damage and/or malfunctioning incurred through non-adherence to these installation instructions.

4. Transport, Storage

The mechanical seal and related equipment maust be transported and stored in the unopened, original shipping box. The warehouse in which the mechanical seals and related equipment are stored must be dry and free of dust. Avoid exposing equipment to large temperature fluctuations and radiation.

Parts or complete mechanical seals that have been dropped or otherwise have been subjected to heavy impacts during transport must not be installed. An inspection by Flowserve or its appointed representative is strongly advised.

If the machine is to be preserved with integrated mechanical seal(s) the preserving medium must not impair the functions of

the mechanical seal(s) by e.g. fouling of the seal faces, hardening, or swelling the secondary seals.

After a storage period of 3 years the mechanical seal must be inspected for its “as new” properties. This applies in particular to the seal faces and secondary sealing elements. An inspection by Flowserve becomes necessary.

The mechanical seal can in principle be transported with suitable means like lifting accessories.

5. Equipment Check

5.1 ! Follow plant safety regulations prior to equipment disassembly:

• lock out motor and valves.

• wear designated personal safety equipment.

• relieve any pressure in the system.

• consult plant MSDS files for hazardous material regulations.

5.2 Disassemble equipment

in accordance with equipment manufacturer’s instructions to allow access to seal installation area.

5.3 Remove existing mechanical seal and gland

or compression

packing and packing gland.

5.4

Make sure the shaft or sleeve and the seal housing face are clean and free of burrs, cuts, dents, or corrosion that might cause leakage past the sleeve packing

or gland gasket

. Replace worn shaft or sleeve. Remove sharp edges from keyways and threads.

5.5 ! Check equipment dimensions to ensure that they are within the dimensions shown in Figures 1 and 2. Critical dimensions include:

• Box Bore (ØC)

• Box Depth (G)

• Distance to First Obstruction (K)

• Pump Frame accomodates Gland OD (ØE)

5.6 Check gland bolting to ensure that bolt diameter and bolt circle

conform to the dimensions shown in Figure 2.

5.7 ! Handle the ISC with care, it is manufactured to precise tolerances.

The sealing faces of the ISC seal are the Primary Ring and the

Mating Ring. They are lapped flat to within three light bands (0.9 µm). Keep the seal faces perfectly clean at all times.

If the pump condition exceeds the above criteria ( including consideration for thermal growth), consult Flowserve Application Engineering for recommendations to avoid seal performance compromises.

Seal Chamber Requirements

The MS may be installed when there are no visible signs of damage to the MS. This applies in particular to the seats, centrings, and the statically sealing O-rings.

6.2 Lubricate the shaft or sleeve lightly with silicone lubricant unless otherwise specified.

6.3 Tighten the Centering Tab screws

6.4 Install the complete ISC cartridge assembly onto the

shaft or sleeve with the centering tabs near the bearing housing. See Figure 3.

For some pumps it may be required to remove the bearing frame before installing the cartridge seal.

Vibrations must be prevented from transferring to the installed ISC during operation, e.g. through structural measures imple

mented on the machine. The machine to take the ISC must be earthed in accordance with

the applicable regulations for electrical installations (e.g. VDE rules) to conduct away any electrostatic build-up and so prevent spark formation.

6.5 Install the pump back plate (seal chamber) and bolt it in place on the bearing frame. See Figure 4.

6. ISC Installation - Single Seal Design

The installation chamber for the mechanical seal must be checked against the corresponding drawing and table of dimensions. It must be ensured that all dimensions, surface qualities, and tolerances (e.g. concentricity, run-out, fits) are observed. The specifications under e.g. ISO 21049 or API 682, DIN 28161, FLOWSERVE publication FSD 101, FLOWSERVE publication FSD127 must be observed.

NOTE:

No seal setting measurements are needed to install the seal. Instructions are for vertically split case end-suction ANSI pumps. Modification of the procedure may be required for other style pumps. Consult Flowserve.

Take care that seal cartridge or components of the seal are handled and carried safely during installation of mechanical seal and that the ergonomic principles are followed. In order to prevent personal injuries the operator should also wear protective clothing as per the plant’s safety regulations.

Precautions must be taken for parts of the mechanical seal that will be used as support to step on during assembly operations. These parts must be protected against slipping, stumbling or falling (for example by using a strut).

6.1 Tools needed for installation: * An open end wrench for the gland bolt nuts * 1/8" (imperial sizes) or 3 mm (metric sizes). Allen wrench (provided) * 3/16" (imperial sizes) or 5 mm (metric sizes). Allen wrench (pro

vided) for sizes >2.500" (65 mm)

to overstress these components, e.g. the max permitted tightening torque must not be exceeded.

6.7 Assemble the pump. Avoid pipe strain. Align coupling properly.

6.8

With the impeller, shaft, coupling, and bearings in their final operating positions, tighten the ISC set screws

See Figure 5.

Inaccurate tightening of these screws can lead to unsafe situation as mechanical seal may move out of the seal chamber when pressure is applied.

Suggested minimum torque values for set screws are as follows: Shaft sizes 1.000” – 2.500” 25 – 65 mm:

4.5 Nm

Shaft sizes 2.625 – 2.750” 70 mm:

13.5 Nm

6.9 Caution: Remove the centering tabs CT from the sleeve collar. See Figure 6. Save the tabs and fasteners for future use when the

If removed re-install

the bearing frame first.

6.6 Position the ISC

with the gland tight against the seal chamber face. If equipment conditions allow, position gland with the outlet port or plugged flush port as close to the 12:00 position as possible. See Sections 7 and 8 for further piping considerations. Otherwise turn the gland so that the vent tap is as close to the 12:00 o’clock position as possible and so that the flush piping will clear the bearing frame.

Caution: Centering Tabs should not be removed or loosened

before tightening the gland bolts and tightening the set screws to the shaft.

Tighten the gland nuts evenly in a diagonal sequence.

Do not over tighten the gland nuts, as this can warp parts and cause leakage. The suggested ISC minimum torque values are as follows:

Shaft sizes 1.000” – 1.937” 25 – 48 mm: 20 Nm Shaft sizes 2.000” – 2.750” 50 – 70 mm: 27 Nm

Components provided by the customer for installing the MS, e.g. the pump cover or fastening screws, must exhibit adequate properties and dimensions. It must not be possible

6.11 See Operational Recommendations

before start-up.

Conduct a static pressure test. Do not exceed the max. pressures.

7. Single Seal Piping and Functional Recommendations

7.1 Install an

adequate seal flush system

. Ensure that piping is connected to the correct pipe ports to prevent unsafe situations. The connections on the mechanical seal are properly marked.

The ISC requires a clean cool environment for maximum seal life.

With a clean cool product, use a bypass flush from the pump discharge (API plan 11) or a bypass flush to the pump suction (API plan 13). With clean hot products use a bypass flush through a cooler (API plan 21). With abrasive products or products that are incompatible with the seal, use a flush from a clean external source (API plan 32).

7.2 Use flush port that coincides with gland markings and direction of equipment rotation. Plug extra NPT opposite of flush (see Figure

7).

7.3 Taps

and

in the gland are quench and drain ports used for fluid quenching, ASME Flush Plan 7362. If they are not used, they should be plugged with pipe plugs.

Escaping leakage must not form an explosive mixture.

7.4 Remove lock outs on pump and valves.

7.5 Do not start up the equip

ment dry to check motor

rotation, etc. Open valves to flood pump with product fluid. Ensure that the seal flush system is operating. Vent air from the casing of the pump and the seal chamber before start-up.

It must be ensured that the machine is protected against penetration by dust and / or that dust deposits are removed at regular intervals so that they cannot exceed a thickness of 5 mm on the surfaces of the faces.

It must be ensured, e.g. in the form of a level monitor, that the running chamber is completely vented and filled with fluid in all operating states if it is to minimise the heat generated by friction and therefore the surface temperature of the seal elements.

Figure 7

If the application limits for running in accordance with these instructions cannot be observed, the temperature of the supply liquid and / or the installed components must be monitored at all times by a device that shuts down the machine once a critical temperature is reached. This device can consist of resistance thermometers or thermoelements.

The seal chamber must be vented carefully before startup.

7.6 Observe the start-up

. If the seal runs hot or squeals, check the seal flush system. Do not allow the equipment to run for any extended time if the seal gets hot or squeals.

8. Dual Seal Piping and Functional Recommendations

Forced ventilation of the seal chamber must be ensured when the circulation pipe is connected. Should there be gas or air pockets in the sealing chamber, these can accumulate with the rotation at the outer diameter of the seal gap at machine startup. This causes the machine to run dry at the seal gap for an indefinite period, and the seal faces can become damaged.

Figure 9. Double ISC with Supply Tank

8.2 For running a dual pressurized seal (double seal), supply a clean compatible barrier fluid to the inlet port at a pressure at least 25 psi (170 kPa) above the seal chamber pressure (see Figure 9). The pressure of the barrier fluid must not exceed the recommended maximum pressure. Flowserve can supply information on barrier fluid flow requirements based on seal size, product temperature, barrier fluid characteristics, and shaft speed.

Monitoring the liquid circulation is a recommended measure for ensuring that the mechanical seal runs properly.

Suitable measures must be implemented to prevent errors in the handling of shut-off and throttling devices installed in the fluid supply.

8.3 For running a dual nonpressurized seal (tandem seal)

, supply a clean compatible buffer fluid to the inlet port at a pressure below the seal chamber pressure (See Figure 10). The pressure in the seal chamber must not exceed the recommended maximum pressure. Flowserve can supply information on buffer fluid flow requirements based on seal size, product temperature, buffer fluid characteristics, and shaft speed.

8.4 The Flowserve Supply Tank is designed to work with the ISC Dual Seal to form a self-contained sealing system. The new circulating feature in the ISC provides a positive barrier fluid flow from the seal cavity to the Supply Tank and back to the seal. In most cases the natural cooling of the piping and tank are adequate to remove seal generated heat. Cooling coils are available with the Supply Tank to increase heat dissipation. The Supply Tank can be used with the ISC Dual Seal in both the double or tandem operating modes.

Recommendation: For enhanced seal performance and reduced

coking, use DuraClear as a barrier fluid. Refer to DuraClear brochure FSD123 or contact a Flowserve seal application engineer for further details.

Figure 10. Tandem ISC with Supply Tank

9. Functional Recommendations

9.1 Do not exceed corrosion limits. The ISC is designed to resist corrosion by most chemicals. However, do not expose the ISC materials of construction to products outside of their corrosion limits. The ISC assembly drawing lists the materials of construction. Consult Flowserve for chemical resistance recommendations.

9.2 Do not exceed

the recommended maximum pressure and speed

limits shown in the ISC brochure.

9.3 Do not exceed the temperature limits of the ISC.

The materials of construction are listed on the ISC assembly drawing. For dual seals using supply tanks with cooling coils, turn on cooling water to the supply tank before start-up.

At all running temperatures the product must not come within 20 K of its evaporating point. Should this not be the case during certain situations (e.g. machine shutdown, startup) forced circulation or adequate cooling of the supply fluid must be generated to promote heat removal.

Escaping leakage must not form an explosive mixture.

9.4 Do not start up or run the ISC dry.

Buffer/barrier fluid must be in the seal cavity for dual seals at all times during pump running. Process fluid must be in the pump volute at all times during single seal running. For special problems encountered during installation, contact your nearest Flowserve Sales and Service Representative or Authorized Distributor.

10. Shut down, Disassembly

The equipment can be shut down at any time. Before the mechanical seal can be removed the equipment and de-pressurized. Barrier pressure (if applicable) must be relieved after the equipment has been de-pressurized.

Operator must persuade himself before starting disassembling of mechanical seal that the external of the equipment is cool enough to be handled without risk.

Product may be released during removal of the mechanical seal. Safety measures and protective clothing may be required as per the plant’s safety regulations.

Dismantling of the mechanical seal is only allowed after machine has been stopped.

Further disassembly of the mechanical seal must be done according to the supplier’s specifications.

11. System Check

Checking of the system, limits itself to monitoring pressure, temperature, leakage and consumption of barrier (buffer) fluid, when applicable.

Routine maintenance of the mechanical seal extends to the monitoring of the set values for pressure, temperature, and leakage quantity.

Maintenance to the mechanical seal is only allowed after machine has been stopped.

The required area for operating the machine or doing maintenance to the mechanical seal must be easy accessible.

12. Repairs

The ISC Seal is designed to provide reliable operation under a wide range of operating conditions. However, there will come a time when the seal will fail as it reaches its normal life expectancy or if it is operated outside of its design capabilities.

This product is a precision sealing device. The design and dimensional tolerances are critical to seal performance. Only parts supplied by Flowserve should be used to repair this seal. These parts are available from numerous Flowserve stocking locations. When ordering replacement parts, refer to the part code and B/M number.

If desired an analysis of the seal can lead to recommendations for improving seal MTBPM. Observations concerning seal life, operating conditions, and the condition of the seal itself should be recorded. A spare backup seal should be stocked to reduce equipment down time.

This seal can normally be reconditioned. When repair is necessary, the centering tabs CT should be reinstalled and the seal carefully removed from the equipment.

Decontaminate the seal assembly and return it, with centering tabs installed, to a Flowserve authorized repair facility with an order marked ´Repair or Replace’. A signed certificate of decontamination must be attached. A Material Safety Data Sheet (MSDS) must be enclosed for any product that came in contact with the seal. The seal assembly will be inspected and, if repairable, it will be rebuilt, tested, and returned to its original condition.

licht eine gleichmäßige Dichtflächenbelastung, sie liegt außerhalb der Prozeßflüssigkeit und ist unempfindlich gegen Zusetzen und Spannungskorrosion. Die Balgdichtungen sind mit rotierender oder stationärer Balgeinheit lieferbar. Die Anordnung mit rotierendem Balg wird eingesetzt, wenn eine Selbstreinigungsfunktion benötigt wird; stationäre Bälge werden benutzt, um eine Fehlausrichtung im Dichtungsraum zu kompensieren.

Funktionsvoraussetzungen

Diese Gleitringdichtung ist für eine zuverlässige Funktion unter weitreichenden Einsatzbedingungen ausgelegt. Die in dieser Produktbroschüre aufgeführten Angaben und technischen

temperaturen der Gleitkörper erfordern, ist auf Anfrage das Flowserve-Dokument “Information / Erklärung zu ATEX 137” erhältlich. Dieses Dokument ermöglicht den Anwendern die Bestimmung typischer Oberflächentemperaturen aufgrund der Dichtungsauslegung, der Betriebsbedingungen und der Gleitkörper-Werkstoffe. Den Anwendern kann es dabei behilflich sein, die Richtlinie ATEX 1999/92/EG (ATEX 137) einzuhalten.

1.4

Funktionsvoraussetzungen

Die ordnungsgemäße Funktion der Gleitringdichtung wird nur

erreicht, wenn folgende Voraussetzungen erfüllt werden:

• Gemäß Spezifikation geläppte Dichtflächen

• Rechtwinkligkeit und Konzentrizität der Welle zur Stirnseite des Dichtungsraums bzw. der Bohrung

• Freie axiale Federbeweglichkeit der befederten Einheit (des Gleitrings)

• Axiale und radiale Arbeitsbewegung der Welle innerhalb der Toleranzen von Flowserve bzw. des Erstausrüsters (je nach dem, welche enger sind).

• Die Dichtung wird für die Einsatzbedingungen verwendet, für die sie ausgewählt wurde.

• Die Anlage mit der/den eingebauten Dichtung/en wird im Rahmen der normalen Parameter betrieben (keine Kavitation, zu starken Schwingungen usw.).

• Belagbildung auf den Oberflächen der Wellen bzw. Wellenhülsen durch z.B. Kristallisation, Polymerisation ist auszuschließen.

• Dauerhafter Flüssigkeitsfilm zwischen den Dichtflächen.

Bauteile umfassen einen Gleitring und (je nach Bauart) ein befedertes Element. Das befederte Element kann eine Feder oder ein Balg sein. Der Gleitring wird zur Welle durch eine Nebendichtung, z.B. einen O-Ring, abgedichtet.

Eine Gleitringdichtung kann als vormontierte Cartridge oder

in einzelnen Komponenten ausgeliefert werden. Die Montage erfolgt gemäß der Zeichnung. Eine Gleitringdichtung kann in Kontakt mit dem zu pumpenden Produkt oder der externen Versorgungsflüssigkeit eingesetzt werden. Zur Schmierung dient ein Flüssigkeitsfilm, der immer zwischen den Dichtflächen vorhanden sein muss. Die Dichtoberflächen werden bei rotierender Welle durch den Flüssigkeitsdichtfilm voneinander getrennt und arbeiten unter diesen Bedingungen nahezu kontakt- und verschleißfrei.

1.3

Explosionsschutz

Die Gleitringdichtung ISC ist eine Standard-Cartridgedichtung und daher als ein Maschinenelement anzusehen. Maschinenelemente sind von den Bestimmungen der Richtlinie 94/9/EG ausgenommen (Produktleitfaden ATEX 95), da sie als integrale Bestandteile einer größeren Maschine (Pumpe, Rührwerk) gelten. Das wurde sowohl vom Ständigen ATEX-Ausschuss der EG als auch von der European Sealing Association (ESA) bestätigt. Auf folgende Websites wird verwiesen:
