3 Face Material TYPE 52/56 CARTRIDGE SEAL DESIGN FEATURES Automatic Seal Face Alignment Vulcan SelfAligning Floating Stationary compemsates for shaft/seal misalignment, seals where rigid designs would fail and commonly increases seal life, by providing a steady true face contract, with full, fluidfilm lubrication and no point contact wear. Centrifugal Forces Act to throw media and particles away from, rather than into, the seal faces. Efficient heat transfer away from the seal faces is engineered by our design and materials. Smooth contoured Geometry Minimises erosion and avoids turbulence. NonClogging Design Multiple springs for even face loading, isolated from the product, prevents clogging by dirty fluids. HASTELLOY C springs are fitted as standard for maximum corrosion resistance and life. Eliminates Shaft/Sleeve Fretting Larger diameter static O Ring seal will not fret nor damage the shaft sleeve and can seal on shaft sleeve previously slightly worn by other seals or gland packing. Hydarulically Balanced Faces Effectively reduces the seal closing forces, giving true running faces with lower friction, heat and wear build up and thus increases the pressure range and the life of the seal. Cartridge Design Preassembled, set and tested for easy, accurate and assured installation. Universal Slotted Gland Design Fits all common bolt sizes and pitch circle diameters. Compact seal design allows fitting to most pumps without modification. Tangential Flush cavity Uses the circumferential motion of the seal to maximize flush circulation, works for both clockwise and anticlockwise seal rotation and avoids the pressure imbalance and vibration frequently induced by flush Easy Shaft Attachment and Torque Transmission Given by even distribution of optimum number set screws. Tangential Quench and Drain Cavity For optimum circulation of barrier, cooling or heating media, or to provide vent (fumes/vapour) and drain (liquid) facilities for controlled leakage. O Ring Sealed Clamp Ring Seals any leakage tangentially away from the bearings/motor. Vital Carbon Restriction Bushing Acts as an automatic centering device, thus eliminating the problem of the seal not being centered and the meddlesome positioning clips. The bushing also greatly restricts loss of any quench media used and of any product upon ultimate failure of the seal. High PV Value Faces The Pressure Velocity (PV) factor of the seal faces largely determines their suitability for, and specifically the amount of heat generated by, the face in any application. Silicon carbide has the best combination of heat dissipation, running, hardness and chemical resistance capabilities of any seal face material. Vulcan fit Triple Phenolic Resin impregnated Carbon Vs silicon Carbide faces as standard to give the highest possible face PV combination. This maximises the capability, performance and life the of seal. Carbon vs Silicon Carbide Carbon vs Tungsten Carbide Carbon vs Ceramic High PV Value Faces Pv Value

4 CARTRIDGE SEAL TYPE 52/54/56 FEATURE Cartridge design: Seal is assembled, loaded, set and tested at our factory BENEFITS 1. The seal can be swiftly and easily fitted by merely clamping it to the shaft and bolting up to the gland face. No measuring of installation dimensions, marking out of the shaft from the gland is required. The seal normally require no pump modification and fits 5/16 (8mm) cross section glands. 2. Time and cost of installation is saved and even more significantly, the principal cause of seal failure i.e. fitting error is avoided. Internally balanced The effective pressure to be sealed at the faces is reduced. This lowers friction, heat build up and wear at the seal faces giving an increase in the pressure that can be sealed and often, significantly increasing the life of the seals. The faces run true with low turbulence generated. In addition, shaft fretting is eliminated by balanced seal designs. Multiple springs in Hastelloy C sealed out of the fluid 1. The extreme corrosion resistance of HASTELLOY C is further enhanced in our design by the springs being sealed out of the fluid. This protects the springs from corrosion and clogging problems. Vulcan fit HASTELLOY C as standard, where lower grade stainless springs are standard to many of our companies. 2. Multiple springs distribute pressure more evenly to the seal faces than a single spring design, can accommodate short working length designs and higher shaft speeds and avoid any risk of catastrophic spring failure. TRUE AUTOMATIC SELF ALIGNING FACES (PATENT APPLIED FOR) Allows the seal to handle shaft misalignment a common feature especially as equipment or bearings become worn. Standard seals with fixed faces will either fail to seal life. Experience shows that selfaligning seals normally significantly outlast fixed face designs.

5 FEATURE CARTRIDGE SEAL TYPE 52/54/56 Carbon restriction bushing fitted as standard BENEFITS Upon ultimate failure of the seal, the carbon acts as a disaster bushing, substantially reducing product leakage to a spray. This minimises product loss and bearing contamination and can (in the right circumstances) allow the seal to be continued to run shortterm until the pump can be taken offline. External clamping For original easy fitting and readily allows any necessary shaft/impellor adjustments. Slotted gland Designed to fit all common bolt sizes and popular bolt circle diameters. Carbon vs silicon carbide faces as standard The PV value of the seal faces largely determines the suitability/capability of a seal for an application and the subsequent life of the seal (barring disastrous outside influences). Carbon vs Silicon Carbide has the highest PV value (at 1750 Bar m/s) of my standard face combination. Most seal companies offer Carbon vs Ceramic (because of cost) with only a 170 (ten times less) PV value and charge more for Carbon vs Silicon Carbide. Why compromise seal capabilities and life? Vulcan offer Carbon vs Silicon Carbide as standard with no increase in cost. Vulcan design fits the Silicon Carbide rings into Stainless Steel housings to avoid common shock damage found in other designs. Air connections Static external oil seal in type 54 design Proven design Type 56 variant has Quench, Flush and Drain connections predrilled in the gland. Vulcan Type 54 uses a Forsheda V Seal with substantial benefits over more common rotary oil seal design. Cartridge seal assemblies have been extensively provided to improve seal reliability, performance and life especially when incorporating selfaligning faces. Fair repair policy based on cost of repairs necessary Our repair programme returns the seal to an asnew condition at a fraction of the new cost. In contrast to our competitors, we charge for the work done, not at some arbitrary (and high) percentage of the new

6 FEATURES OF CARTRIDGE SEALS Centrifugal forces; Act to throw media and particles away from, rather than into, the seal faces. Efficient heat transfer away from the seal faces is engineered by our design and materials. Hydraulically Balanced faces; Effectively reduces the seal closing forces, giving true running faces with lower friction, heat and wear buildup and thus increases the pressure range and the life of the seal. Universal Slotted Gland Design; Fits all common bolt sizes and pitch circle diameters. Compact seal design allows fitting to most pumps without modification. Cartridge Design; Preassembled, set and tested for easy, accurate and assured installation. Tangential flush Cavity; Uses the circumferential motion of the seal to maximise flush circulation to the seal, works for both clockwise and anticlockwise seal rotation and avoids the pressure imbalance and vibration frequently induced by flush liquid entering the seal chamber axially against the seal. Balanced Design; Eliminates shaft / sleeve fretting Tangential Quench and Drain Cavity; For optimum circulation of barrier, cooling or heating media or to provide vent (fume vapour) and drain (liquid) facilities for controlled leakage. Larger Diameter static O Ring Seal; Can seal on shaft sleeves previously slightly worn by other seals or gland packing. Smooth Contoured Geometry; Minimises erosion and avoids turbulence. O Ring Sealed Clamp Ring; Seals and leakage tangentially away from the bearings/motor. NonClogging Design Multiple springs, isolated from the product, prevents clogging by dirty fluids and gives even face loading. HASTELLOY C springs are fitted as standard for maximum corrosion resistance and life. High PV Value Faces The Pressure Velocity (PV) factor of the seal faces largely determines their suitability for, and specifically the amount of heat generated by the faces in, any application, Silicon carbide has the best combination, of heat dissipation, running, hardness and chemical resistance capabilities of any seal face material. Vulcan fit Triple Phenolic Resin Impregnated Carbon Vs Silicon Carbide faces as standard to give the highest face PV combination. This maximises the capability, performances and life of the seal. Vital Carbon Restriction Bushing; Acts as an automatic centering device thus eliminating the problem of the seal not being centered and the need for meddlesome positioning clips. The bushing also greatly restricts loss of any quench media used and of any product upon ultimate failure of the seal. Automatic Seal Face Alignment Vulcan Self Aligning Floating Stationary compensates for shaft/seal misalignment, seals where rigid designs would fail and commonly increases seal life by providing a steady true face contact with full fluid film lubrication and no point contact wear. Easy Shaft Attachment and torque transmission given by even distribution of optimum number of set screws. Solid Silicon Carbide Seat Face Is not subject to heat check as is, solid or plated, Ceramic, Chrome Dioxide, Tungsten Carbide, NiResist or stellite.
