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. 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.

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 pumps and wastewaterpumps.

8 Pressures to 75 PSI. Temperature: -40 F to +400 B(Shaft Diameters 3/8" through 1")FEATURES:Afull-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, submersible pumps 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 5-1/2")FEATURES:Self adjusting elastomer bellows compensate for abnormal shaft end playandprimary face sealing wear. Effects 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.

9 Damaging stresses on the elastomer bellows are is eliminated, thus protecting shaft and sleeve against wear and 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 contact. Corrosion 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 1")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.

10 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 -20 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. Temperature -40 F to +400 W(Shaft Diameters 1/2" through 6")FEATURES:Multi Spring, PTFE wedge design for use in extreme temperatures / chemical available in a balanced design SERVICES:Corrosive fluid applications, extreme temperatures. Pressures to 350 PSI. Temperature -75 F to +500 X(Shaft Diameters 1/4" through 6")FEATURES:Multi Spring, O-ring design, unitized construction, flexible design compensates for shaft misalignment for high performance and longer seal life.
