Additionally, mechanical Seals offer these important SEALINGP roper selection and installation of our Seals results in less pumpage loss,cleaner facilities, less fire hazard, no danger from fumes and no contaminationof the fluid being RUBBING FRICTION BETWEEN SHAFT AND SEAL PARTSR eplace packing with a mechanical seal and avoid expensive shaft or Seals MEANS LONGER SERVICE LIFEC ompared to packing, mechanical Seals are more flexible, and are able tocompensate for shaft deflection, axial and radial end play, vibration and sealface FRICTION MEANS VALUABLE POWER SAVINGSM echanical Seals use less friction than packing.

6 Therefore, they require lesshorsepower 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 three lightbands, which maintains the necessary face film lubrication, resulting inpositive leakage SELECTION OF MATERIALS OF CONSTRUCTIONOur Seals come in a wide variety of materials.

Centrifugal pumps Pool and Spa pumps Compressors Progressive Cavity pumps Gear Boxes Rotary Lobe pumps Gear pumps Slurry pumps Jet pumps Submersible pumps Petrochemical pumps Turbine PumpsFEATURES OF SEAL TYPES A, B, C, D, E, G, Q, W, XTYPE A(Shaft Diameters 5/16" through 1")FEATURES:Compact, unitized, single spring, elastomer bellows seal.

7 The factory-assembled, one piece designpermits fast, easy installation and the full-convolution elastomer bellows provide maximum flexibility in compensatingfor shaft movement and :Centrifugal water pumps , deep and shallow well jet pumps , swimming pool and wastewater to 75 PSI. Temperature: -40 F to +400 B(Shaft Diameters 3/8" through 1")FEATURES:A full-convolution elastomer bellows provide maximum flexibility in compensating for shaft movementwhile torsional stress on the bellows is controlled by a dent and grove positive drive :Small centrifugal water pumps , sump pumps , submersible and swimming pool to 75 PSI. Temperature: -40 F to +400 C(Shaft Diameters 5/16" through 5-1/2")FEATURES:Elastomer bellows seal, non-clogging, single coil spring, The drive band s notch design eliminatesoverstressing of the :Centrifugal, hydraulic, rotary and turbine pumps , compressors, mixers, blenders and to 150 PSI. Temperature: -40 F to +400 D, E(Shaft Diameters 1/2" through 5-5/8")FEATURES:Self adjusting elastomer bellows compensate for abnormal shaft end playand primary face sealing of radial and axial shaft end play are minimized byuniform spring drive is transmitted through the drive band and drive notches, which absorbbreakout and running torque.

8 Damaging stresses on the elastomer bellows are is eliminated, thus protecting shaft and sleeve against wear and scoring. Theresult is long seal seal s large single-coil spring is much sturdier than a multiple spring construction design. The spring is non-clogging, self-cleaning andwill not foul up due to fluid and clogging problems are :Used throughout industry in all types of rotary shaft equipment such as pumps , mixers, blenders, agitators and can be used in an extremely wide range of services from water and steam to chemicals and to 350 : -40 F to +425 FBalanced Seals - Pressures to 1200 PSI. Temperature: -40 F to +450 F (dependent upon sealed fluid, RPMs, seal size, and seal face materials)TYPE G(Shaft Diameters 7/16" through 3-1/2")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.

9 Interference fit ofprimary ring insures positive drive while avoiding high face distortions associated with crimped :Small centrifugal pumps used in Pool & Spa, Well Water, & HVAC to 150 PSI. Temperature -30 F to +300 Q(Shaft Diameters 1/2" through 2 -1/4")FEATURES:Press fitted, rubber diaphragm protects metal components, spring loadedSERVICES:Icemaker and appliance applications, general purpose food to 30 PSI.

Material Code found on the front cover Head type (see front cover fold-out.) Use caliper to measure inside diameter (ID) and outside diameter (OD)SEAL HEADS TYPES A and BIdentify seal head type - Determine Seal Size:Measure the inside diameter (ID) (dimension A)Measure the outside diameter (OD) (dimension B)The operating height is generally the same for all A and B Seals of the same shaft size. More positive identification will result from calculating the mating ring dimensions below. If unable to positively identify the seal, consult Seal HEADS TYPES C, D and EIdentify seal head type - Determine Seal Size:Measure ID of the bellows (dimension A) as installed in the seal approximately .016" additional for rubber the head OD (dimension B)Step 1.
