3 Product Description
3.1 General description
Model 3298
Model 3298 is a sealless, close-coupled or frame-mounted, centrifugal pump with an enclosed impeller
that is driven by a synchronous magnetic coupling. All sizes of the 3298 meet the dimensional standards
of ANSI B73.1 except for 1x1.5-5 and the 1.5x2-6.
Model SP3298
SP3298 is a self-priming, sealless, close-coupled or frame-mounted, centrifugal pump with an enclosed
impeller that is driven by a synchronous magnetic coupling. The pump and the frame or adapter feet lo-
cations meet ANSI B73.1 dimensional standards.
Model V 3298
V3298 is a vertical in-line, sealless, close-coupled centrifugal pump with an enclosed impeller that is driv-
en by a synchronous magnetic coupling. Model V3298 meets the dimensional standards of ANSI B73.2.
Casing
The casings are one-piece cast ductile iron lined with 1/8-inch Tefzel®1 and have ANSI class 150 flang-
es with a Tefzel® raised face. The 3298 and SP3298 are end-suction, top centerline discharge, and are
self-venting. The V3298 is side-suction, side-discharge, and is also self-venting.
Impeller magnet assembly
The 3298 family uses a one- or two-piece impeller magnet assembly. The magnet ring is balanced to ISO
1940 G6.3 levels and is sealed within the solid, enclosed Tefzel® impeller magnet assembly.
Stationary shaft
The impeller magnet assembly rotates about a solid stationary silicon carbide shaft. The shaft is support-
ed at one end by the containment shell and at the other end by the Tefzel® bearing spider.
Bearing spider
The bearing spider, constructed from solid Tefzel®, houses one of the key silicon carbide thrust bearings
in the pump and supports the stationary shaft at one end.
Rear impeller wear ring
A rear impeller wear ring is standard on M and L group pumps. A wear ring is not required on theS
group. The wear ring is pressed into the rear of the impeller assembly. The wear ring reduces axial thrust
in the M and L group pumps.
Magnetic coupling
The magnetic coupling is a coaxial synchronous type using rare earth magnets of neodymium iron
(NdFe). This concept results in a compact design and allows the impeller to turn at the same speed as
the motor, which means that there is no slip between the drive and the driven magnets.
Containment shell
The containment shell isolates the pumped liquid from the atmosphere. The containment shell construc-
tion is backed with vinylester FRP.
3 Product Description
3298 Family Installation, Operation, and Maintenance Manual 15

Bearings
The standard material for radial bearings and thrust bearings is carbon. Pure Sintered Alpha Grade Sili-
con Carbide or DryGuard® Pure Sintered Alpha Grade Silicon Carbide are optional.
Standard close-coupled mounting
The drive magnet assembly is keyed, setscrewed, and mounted directly to the motor shaft. This arrange-
ment eliminates the need to perform pump-to-motor alignment.
Optional frame-mounted power end
The standard configuration for the optional power end is cast iron with flood-oil-lubricated ball bearings.
Pure oil mist systems are available as an option. For the protection and reliability of the bearings and the
lubricant, a labyrinth seal is provided. On the inboard side a lip seal is used to prevent leakage of oil into
the magnetic drive assembly. The frame-mounted power end is not available on the V3298.
