5 If part number is not found, refer to the Seal SizingGuideon Page 4. With this information, turn to the Dimensional Cross-Reference section (Pages112-161). Locate the needed seal size, then the head and mating ring type. Cross-reference with thematerial code to obtain the correct Seal Mfg. part a Complete Line of QUALITY Seals For More Than 50 Years CONTENTS2 Our seals are designed to give long life, provide automatic self-adjustment and reduce maintenance costs. Additionally, mechanicalseals offer these important SEALINGP roper selection and installation of our seals results in less pumpageloss, cleaner facilities, less fire hazard, no danger from fumes and nocontamination of the fluid being RUBBING FRICTION BETWEEN SHAFT AND SEAL PARTSR eplace packing with a mechanical seal and avoid expensive shaft or sleeve SEALS MEANS LONGER SERVICE LIFEC ompared to packing, mechanical seals are more flexible, and are ableto compensate for shaft deflection, axial and radial end play, vibrationand seal face FRICTION MEANS VALUABLE POWER SAVINGSM echanical seals use less friction than packing.

6 Therefore, theyrequire less horsepower consumption. PRECISION LAPPED SEALING SURFACESP ositively control leakage and eliminate break in SPEEDS AND PRESSURESOur seals are designed for higher speeds and SURFACES OF MATING FACESS ealing surfaces are precision lapped to a flatness of one to threelight bands, which maintains the necessary face film lubrication,resulting in positive leakage control. BROAD SELECTION OF MATERIALS OF CONSTRUCTIONOur seals come in a wide variety of materials. Choose the correctcombination of elastomer, metallurgy and sealing faces for your application.

7 312 )FEATURES: Compact, unitized, single spring, elastomer bellows seal. The factory-assembled, one piece design permits fast, easy installation and the full-convolution elastomer bellows provides maximum flexibility in compensating for shaft movement and : Centrifugal water pumps, deep and shallow well jet pumps, swimming pool and wastewater pumps. Pressures to 75 PSI. Temperature: -40 F to +400 B(Seal Sizes .375 )FEATURES: A full-convolution elastomer bellows provide maximum flexibility in compensating for shaft movement while torsional stress on the bellows is controlled by a dent and grove positive drive : Centrifugal water pumps, sump pumps, submersible and swimming pool pumps. Pressures to 75 PSI. Temperature: -40 F to +400 C(Seal Sizes.

8 312 )FEATURES: Elastomer bellows seal, non-clogging, single coil spring, The drive band s notch design eliminates overstressing of the : Rotary and turbine pumps, compressors, mixers, blenders and to 150 PSI. Temperature: -40 F to +400 D, E(Seal Sizes .500 )FEATURES: Self adjusting elastomer bellows compensate for abnormal shaft endplay and primary face sealing wear. Effects of radial and axial shaft end play areminimized by uniform spring drive is transmitted through the drive band and drive notches, whichabsorb breakout and running torque. Damaging stresses on the elastomer bellowsare prevented. Slippage is eliminated, thus protecting shaft and sleeve against wearand scoring. The result is long seal seal s large single-coil spring is much sturdier than a multiple spring construction design.

9 The spring is non-clogging, self-cleaning and will not foul up due to fluid contact. Corrosion and clogging problems are : All types of rotary shaft equipment such as pumps, mixers, blenders, and compressors. Wide range of services from water and steam to chemicals and to 350 PSI. Temperature: -40 F to +425 F Balanced Seals - Pressures to 1200 PSI. Temperature: -40 F to +450 FTYPE G(Seal Sizes .437 )FEATURES: A compact unitized single spring elastomeric bellows shaft seal. Innovative full convolution bellows and interlocking drive band design allows for positive drive and greater tolerance to misalignment. Interference fit of primary ring insures positive drive while avoidinghigh face distortions associated with crimped : Small centrifugal pumps used in Pool & Spa, Well Water, & HVAC applications.

10 Pressures to 150 PSI. Temperature -30 F to +300 F. TYPE Q(Seal Sizes .500 )FEATURES: Press fitted, rubber diaphragm protects metal components, spring loadedSERVICES: Icemaker and appliance applications, general purpose food service. Pressures to 30 PSI. Temperature -40 F to +400 W(Seal Sizes .500 )FEATURES: Multi Spring, PTFE wedge design for use in extreme temperatures / chemical applications. Unitized construction.
