Goulds Pumps 3298 - IOM - Manual (Page 17)

Product Description
Bearings
The standard material for radial bearings and thrust bearings is carbon. Pure Sintered Alpha
Grade Silicon 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
arrangement 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.
