SEALOGIC’s “GOLD STANDARDTM” Super-Upgraded Recirc.-Pump . . . for
Vapor Corporation’s “CIRCULATICR”Coiled-Tube Packaged Steam-Generators


We manufacture “superior-to-O.E.M.-quality” new pumps, dimensionally-interchangeable
with the standard DEAN “RS”. We also modify, upgrade & rebuild existing pumps . . . both the DEAN and the WORTHINGTON / VAPOR / THERMOGENICS-units . . . retrofitting the following vastly-superior components, in the process ! It is not uncommon for this to result in 10-or-20-fold increases in the “Service-Lives” of these pumps on these highly- demanding applications, and annual savings of many thousands-of-dollars in operating and maintenance costs !

( 1 ) “TRANSTHERM R” Mechanical-Seal . . . our proprietary, patented, specifically-
engineered cartridge-design, proven to be THE best seal available for such
“High P-V-T Applications” ! ( see separate brochure for details on this unique seal design )

( 2 ) Heavy-Duty, Solid Stainless-Steel Shaft . . . UNS# S17400 alloy, with greater strength
and hardness than the O.E.M.-material . . . with larger diameters and no wear-sleeves
. . . greatly-increased “Deflection-Index” ( ie. L 3 / d 4 “stiffness-ratio” ), ends vibration
problems ! . . . all “dynamic-contact” is eliminated, so there is never any wear or
need for future repair or replacement !

( 3 ) SKF Cylindrical-Roller Bearing used as the “Radial-Bearing” . . . this unit has a
“Dynamic-Load-Rating” which is 188 % that of the O.E.M.-ball-bearing !

( 4 ) SKF “EXPLORER R” Spherical-Roller Bearing used as the “Thrust-Bearing” . . . this
latest SKF development represents “the state-of-the-art”, and has a “Dynamic-Load-
Rating” which is 245 % that of the O.E.M.-ball-bearing !

( 5 & 6 ) SEALOGIC “Bearing-Isolator-Seals” . . . 2-component, non-contacting, totally
non-wearing ! . . . 100 % lube-containment and 100 % moisture and contaminant-
exclusion, INDEFINITELY ! . . . the exact opposite of the O.E.M.-rubber-lip-seals,
which have an effective service-life of a few hundred hours, and hence require that
their pumps be fitted with “automatic-oilers” to constantly replenish the weeping oil !

( 7 ) Cooling-Coil in the Oil-Sump . . . . highly efficient, requiring less flow, while being
more effective than pump-designs which utilize “cooling-jackets” around the
bearing-frame ! . . . when competitive designs cool the surrounding metal, rather
than the actual lube-oil, it can be very counter-productive, “shrinking” the bearing
outer-races, decreasing internal clearances, & increasing frictional-heat generated !
. . . . Cooler lube-oil is far more effective, lasting many times longer, greatly extend-
ing bearing-performance !

( 8 ) Premium Quality, Long-Life SYNTHETIC OIL . . . . tens-of-thousands-of-hours
service possible with our top-quality, high-temperature-rated lube-oil !


( 9 ) “No-Mistake” BULLSEYE SIGHT-GLASS . . . . see the actual oil level and condition
of the oil in the sump, not just that of the oil in the “cup” of an automatic oiler.


( 10 ) Magnetic Drain-Plug . . . . a little “added insurance” against any possibility of
there being metallic wear-particles suspended in the oil.


( 11 ) “Drain-Back Grooves” in the bearing frame to ensure that you don’t get “static-
pockets” of oil trapped on the outboard sides of either bearing.
