Leak overflow can be selectively discharged. Circulation according to API 8 / ISO 10: Plan 1, Plan. Quench fluid supply systems are used to lubricate single or tandem mechanical seals. They act as a convenient fluid reservoir. The fluid exchange takes place by the principle of termosiphon or forced circulation, e.g. with an external pump. Technical Features Available in a range of different material combinations, it is suitable for a wide range of challenging operating conditions. Tank made of 1.71 steel: high resistance to corrosive media. Integrated overflow for the selective discharge of leaks. Additionaly or alternatively to the sightglass, it is possible to use a level switch to control the fluid volume. Combined fill and ventilation filter in the coolant tank for reliable operation. Design for average temperatures up to +00 C (+ F). Item 1 Storage tank (Capacity l) Inlet filter with vented cap Sightglass or level switch Name plate Overflow G 1/8 A B C Connections To the mechanical seal From the mechanical seal Filling Notes Install the coolant reservoir approx. 1 to m (. to. ft) above the mechanical seal. Install the connecting pipes to the mechanical seal with low resistance. Pipes should be automatically vented in the direction of the tank. It is imperative to avoid pockets of air. The minimum filling must always be above the side connection connector (in the case of the thermosiphon principle). Cooling fluid systems can be operated in two different modes: Deadend quench (Plan 1): Quench liquid from a raised tank. The characteristic feature of this principle is that there is no heat dissipated by the system. Installation, Details, Options Functional description Quench fluid systems are employed: to absorb leakage to monitor the leakage rate (e.g. through periodic reading of the level in the tank). to lubricate and to cool the outboard mechanical seal in a tandem arrangement. to preven icing. to protect against dry running. to stabilize the lubricating film. to exclude air from the media in order to prevent a reaction with oxygen in the air Circulation (Plan ): Quench liquid from a raised tank; External tank, without pressure; Thermosiphon or forced circulation. In this case the heat is dissipated by the circulation. However, the convection cooling capacity is minimal.

The API 8, rd edition, to ISO 10, contains sealing and supply systems for applications in refineries and the chemical industry. API 8 includes a seal selection procedure as well as an aid for selecting buffer/quench fluids, seal supply systems and modes of operation. Cartridge solutions are specified for all applications. API 8 requires all parts of the seal (including its cover and shaft sleeve) to be supplied by the seal manufacturer. For the purposes of qualifying the seals, all standard types and arrangements have to be put through stipulated dynamic trial runs under defined conditions.

202 TTVORings Conical springs Types of drive Viscosity v Double PTFEencapsulated 0rings of the type used in STRAMEK mechanical seals combine the elasticity of the core materials (synthetic rubber) with the chemical and thermal resistance of the PTFE. The material PTFE features good chemical and thermal resistance, but it also displays a Coefficient of exp / 0C C00 Temperature high degree of rigidity, a low coefficient of thermal conductivity, an unfavourable expansion characteristic (see graph) and a tendency to cold flow. It is advisable, therefore, to avoid the use of Orings made of solid PTFE. Rounded edges Joint on outer teflon jacket facing against direction of assembly Mechanical seal direction of assembly The assembly position of double PTFEencapsulated elastomers is critical. Care must be taken to ensure that the joint on the outer jacket faces against the assembly direction, as otherwise there is a risk of the jacket opening and being pulled off. Bending of the jacket must be avoided at all costs to prevent leaks. Slip TTV rings onto tubes for safe storage. Screw locking If no special provision is made for locking screw thread, use set screw with a suitable adhesive (e.g. Loctite) after removing any grease. When a conical spring is used for driving the seal, the mechanical seal becomes dependent on the direction of rotation. Looking toward the sliding face of the rotating parts of the seal, shafts rotating in clockwise direction require righthand springs and shafts rotating in anticlockwise direction require lefthand springs. Mounting the conical spring is easier if you twist it onto the shaft with a screwing action in the same direction as the spring coiling. This screwing action will cause the spring to open. For brief reversals of the direction of rotation we recommend other seals. Lefthand spring anticlockwise shaft Looking towards the mechanical seals Drive side (viewing direction) Direction of shaft rotation: clockwise Direction of spring coiling: clockwise Mounting: Push spring onto shaft and turn simultaneosly clockwise Righthand spring clockwise shaft Pressure vessel regulations Requirements imposed by various international standards for Pressure Vessel Code on Group III pressure vessels (Section 8) International Pressure Vessel Code orders that pressure vessels be built and operated in accordance with the generally valid rules of engineering (such as the German AD Code, ASME etc). AD Bulletin W requires every pressurebearing part made of austenitic steel to be accompanied by a material certificate EN B or.1c. The manufacturer must subject every pressure vessel to a pressure test. Every pressure vessels must be issued with a certificate confirming its correct production and pressure testing in accordance with the Pressure Vessel Code. This certificate is included with the delivery. For a seal to function properly, the shaft torque must be transmitted uniformly to the shaft sleeve and/or rotating parts under all operating conditions. Depending on the seal design it is necessary to make allowance for centrifugal and axial forces and in some case to observe special installation instructions. Incorrect fitting can cause, for example, jamming and deformation of the seal. Typical arrangements Shrink disk Set screw with cone point Allen set screw with full dog point Conical spring Shrink disk Clamping set Set screw with cup point Drive key Spring loaded drive pin The pressure necessary for the transmission of torque is generated through clamping force on lubricated conical surfaces. The shrink disk couplings can be released at any time by slackening the tensioning screws. All the parts involved are subjected to elastic deformation only, o the original clearance is restored once the screws are released. Provided the conical surfaces are undamaged, the shrink disks can be retensioned any number of times (ensure correct lubrication). Shaft sleeves should not have a clearence diameter under the shrink disk and should make full contact with the shaft.

203 Technical Information Circulation For single seals it is generally advisable to install a circulation pipe from the discharge nozzle of the pump to the seal chamber. A pipe size G 1/ is normally sufficient. There should be a close fitting neck bush between the pump casing and the seal chamber. Flushing Flushing systems are installed in accordance with DIN ISO 1, Appendix E, Plan No. 08a or API 10, Appendix D, Plan. A clean and mostly cold external medium is injected into the stuffing box in the area of the sliding faces via on orifice (throttle) into the medium to be sealed. Flushing is used either to lower the temperature or to prevent deposits for ming in the area of the mechanical seal. Again it is recommended that a close fitting neck bush is employed. Quench Quench is the term commonly used in sealing engineering for an arrangement that applies a pressureless external medium (fluid, vapour, gas) to a mechanical seal's faces on the atmosphere side. A quench is used on the one hand when a single mechanical seal does not function at all or only within certain limits without auxiliary measures or when a double mechanical seal with pressurized buffer medium is unnecessary. When an integral stationary seat stop is fitted, the quench pressure should not exceed 1 bar. A quench performs at least one of the duties described below. In some cases, for mechanical seals to function correctly the conditions in which they operate must be altered. This depends on the seal type, the duty conditions including environmental protection, and the type of equipment into which the seals are fitted. A simple change to a single seal's operating conditions in a deadend arrangement can be made, for instance, by adding a recirculation line from the pump discharge to the seal chamber (API Plan 1 ). As operational demands increase, so too must the capabilities of the supply units to support the mechanical seal. The following section contains the necessary information for the correct selection of supply systems and auxiliary equipment to ensure reliable operation of your mechanical seals. To guarantee the correct working of double mechanical seals, the buffer inter space (between the product side and the atmosphere side of the mechanical seal) must be completely filled with clean buffer medium. Before starting up double mechanical seals it is vital, therefore, to ensure a sufficient rate of circulation of the buffer fluid The buffer fluid pressure should lie 10 % or at least 1. to bar above the maximum pressure to be sealed. The flow rate must be controlled to ensure that the temperature of the buffer medium at the outlet lies below approximately 0 C and that it does not exceed boiling point under any circumstances. The maximum acceptable inlet/outlet temperature differential is 1 K. The buffer fluid outlet lies at the highest point of the stuffing box for automatic venting of any vapour. In view of the basic conditions of opera tion, a buffer system must perform the following functions: Buffer systems Buildup pressure in the buffer inter space Compensation of leakage Circulation of the buffer medium Cooling of the buffer medium Cooling of the seal Buffer fluid systems for liquidlubricated mechanical seals break down into two basic categories: Open circuit A circuit in which both the circulation and the pressurization take place through a single buffer fluid system. After each circuit the buffer fluid is relieved and collected in a pressureless tank. Fluid quench Absorption or removal of leakage by the quench medium Monitoring of the mechanical seal's leakage rate by periodic measurement of the level of the quench medium in the cir culation vessel or thermosyphon vessel Lubrication and cooling of the standby mechanical seal Exclusion of air: For media which react with atmospheric oxygen the queching medium stops the leakage making contact with the atmosphere Protection against dry running: For applications subject to brief, periods of vacuum and operation of pumps without pumping liquid (submersible pumps) the quenching medium prevents dry running of the mechanical seal Stabilization of the lubrication film: For operation under vacuum and/or sealing pressures close to the vapour pressure, the quenching medium stabilizes the lubrication film Cooling or heating of the outboar side of the mechanical seal. Steam quench Heating: For media with a high melt ing point the vapour quench prevents the leakage from solidifying in that area of the mechanical seal critical for its properfunctioning Exclusion of air Removal of leakage Standard cm gas/g solvent Nitrogen Mineral oil * Closed circuit In this type of circuit all the components are kept under the same pressure.

204 Buffer medium The buffer medium fulfills two functions it dissipates the heat generated by the seal and it prevents the product from penetrating the sealing gap to any appreciable degree. Any liquid and any gas can be clrosen as buffer medium, with due consideration to the corrosion resistance of the parts it comes into contact with and to its compatibility with the process medium and surroundings. The buffer medium must not contain any solids. It is particularly important that liquid buffer media do not tend to precipitate and that they have a high boiling point, a high specific thermal capacity and good thermal conductivity. Clean, demineralised water satisfies these requirements to a high degree. Hydraulic oil is often used in buffer fluid units and water in closed buffer fluid circuits.

For general considerations and calculations (see following sections), a coefficient of friction of between 0.0 and 0.08 can be applied as a good approximation. As can be seen in the graph, a lower value is obtained under improved conditions of lubrication, e.g. due to partial buildup of hydrodynamic pressure in the sealing gap. On the other hand, when a mechanical seal is run under purely hydrodynamic conditions of operation, the coefficient of friction will rise as the speed increases similar to hydrodynamic bearings. Microfinished sliding faces made of various materials display the following average, arithmetic mean roughness values (Ra): The turbulencerelated consumption of power is not significant until the circumferential speed reaches 0 m/s. It must be given due consideration particularly with special seals. The balance ratio and the load factor are practically identical when the pressure differentials to be sealed are large. The friction at the dynamic secondary seals pr is usually disregarded in the calculation. Sliding pressure PG The term "sliding pressure" is understood to be the surface pressure on the two sealing faces which remains after subtracting all those forces that act on the seal face and which are balanced by hydraulic pressures. The sliding pressure is conditional on the pressure differential to be sealed, the balance ratio, the pressure conditions inside the sealing gap i.e. gap between the seal faces (pressure gradient factor) and the spring pressure. The pressure gradient factor k] can assume values between 0 and 1, depending on the geometry of the two sealing faces. For sealing gap geometries which converge in leakage direction Vgap for externally pressurized seals the value of k1 is > 0., while for sealing gap geometries which diverge in leakage direction Agap for externally pressurized seals the value of k1 < 0.. For simplified calculations the value of k1 is generally taken to be 0.. Under unfavourable conditions the sliding pressure can become negative, causing the sealing faces to open resulting in excessive leakage. PG = p. (k k1 ) + Pf 1 Gap width h Seals with contacting faces In contact seals with a theoretically parallel sealing gap, the distance between the two sealing faces is conditional on the roughness of the surfaces. Numerous measurements taken in the laboratory and in practice with due allowance for external factors indicate that a mean gap width of less than 1 mm can be used as a basis for calculating the normal degree of leakage. Seals with noncontacting faces Hydrostatically or hydrodynamically balanced, noncontacting mechanical seals adjust automatically to a defined gap width during operation. The width of the gap depends mainly on the shape of the gap in radial as well as circumferential direction, on the operating conditions and on the medium.

The power consumption due to turbulence created by the rotating parts. The lower the roughness value, the higher the percentage bearing area and hence the higher load capacity of a mechanical seal. 0 Example: dm = 170 mm n = 00 min1 Vg = 0 m/s k + Pf Pr p Mean sliding Face diameter dm (mm) Technical Information Contact friction ) in (m f Sha dn ee t sp Sliding velocity Vg The sliding velocity is usually quoted in relation to the mean sliding face diameter. Cooling water requeriments When estimating the amount of cooling water required by heat exchangers it can be assumed that the temperature of the cooling water will increase by K between the inlet end the outlet. This means that 1 l/min of cooling water dissipates 0 W Sliding verlociti vg Heat transfer The total power consumption of a mechanical seal has to be dissipated into the medium or the buffer fluid by means of appropriate measures in order to stop the seal from overheating. The necessary fluid flow rate for removal of the power losses is calculated by V = PR + PV T c Under certain conditions of installation or operation heat may pass from the product to the sealing compartment and will need to be taken into account when calculating the circulation rate.

208 Prior to installation To fit a seal you will need its installation and operating instructions with the correct drawing. Before starting, check the dimensions, the maximum acceptable deviations ano the geometrical tolerances of the machine. Edges and shoulders All edges and shoulders onto or into which the mechanical seal is pushed during installation must be chamfered, deburred and rounded off tn less than 0 x mm. Dimensional deviations Acceptable deviations for dimensions having no tolerance specification: ISO 78 Part 1, fine/medium for linear and angular dimensions Part, tolerance class K for general geometrical tolerances Axial runout Mounting face Axial runout depends on the speed.

Seal chamber bore For sliding velocities of vg < m/s the concentricity tolerance of the seal chamber in relation to the shaft should not exceed. mm, and when pumping screws are used it should not exceed 0.1 mm due to the effect of the pumping characteristic. If these values are exceeded please contact Stramek. Absolute cleanliness and care are essential when fitting mechanical seals. Dirt and damage to sliding faces and 0 rings jeopardize a seal's function. Any protective covering on the sliding faces must be removed without trace. Never put lubricant on the sliding faces mount only in a completely dry, dustfree and clean state. The accompanying installation instructions and the notes on the assembly drawings must be observed exactly. Installation Fitting advice To reduce the friction an 0rings when mounting seals on a shaft or when inserting seal cartridges in their housing, apply a thin coating of silicon grease or oil to the shaft or housing (N.B.: this does not apply to elastomer bellows seals). Never allow EP rubber 0rings to come into contact with mineral oil or grease. When inserting stationary seats, be careful to apply even pressure and use only water or alcohol to reduce 0ring friction. Screw locking If no special provision is made for locking screw threads, use set screws with a suitable adhesive (e.g. Loctite) after removing any grease. Venting To prevent damage to the sliding faces from dry running, the buffer space must be carefully vented after you have installed the seal. This is particularly important for those types of buffer fluid systems that do not vent themselves or are partially self venting (double seal with buffer fluid systems).
