PUMP DESCRIPTION
The Model 3298 is a sealless close coupled or frame
mounted centrifugal pump with an enclosed impeller that is
driven by a synchronous magnetic coupling and meets
dimensional standards of ANSI B73.1. (The 1x1
1
2
-5 is not
ANSI dimensional.)
The SP 3298 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 frame / adapter feet locations meet ANSI B73.1
dimensional standards.
The V 3298 is a vertical in-line sealless close coupled
centrifugal pump with an enclosed impeller that is driven
by a synchronous magnetic coupling and meets the
dimensional standards of ANSI B73.2.
Casing - The casings are one piece cast ductile iron lined
with 1/8" TEFZEL
®1
and have ANSI class 150 flanges with
a TEFZEL
®
raised face. The 3298 and SP 3298 are end
suction, top centerline discharge and are self-venting. The
V 3298 is side suction, side discharge and is also
self-venting.
Impeller Magnet Assembly - The 3298 family utilizes 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
supported at one end by the containment shell and 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 - is standard on M and L group
size pumps and is not required on S group sizes. The wear
ring is pressed into the rear of the impeller assembly. The
wear ring reduces axial thrust in the M and L group size
pumps.
Magnetic Coupling
- is a coaxial synchronous type using
rare earth magnets. This concept results in a compact
design and allows the impeller to turn at the same speed as
the motor, (i.e. there is no slip between the drive and driven
magnets.)
Magnets
- Neodymium Iron (NdFe).
Containment Shell - isolates the pumped liquid from the
atmosphere. The containment shell construction is backed
with vinylester FRP.
Radial Bearings and Thrust Bearings - Goulds standard
bearing material is carbon with optional Pure Sintered
Alpha Grade Silicon Carbide or DryGuard™ Pure Sintered
Alpha Grade Silicon Carbide.
Standard Close Coupled Mounting - The drive magnet
assembly is keyed, set screwed and mounted directly to the
motor shaft. This arrangement eliminates the need to
perform pump/motor alignment.
Optional Power End
3
- The standard configuration is cast
iron with flood oil lubricated ball bearings. Pure oil mist
systems are available as an option. For 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.
