PUMP DESCRIPTION
The Model 3296 is a sealless frame-mounted
centrifugal pump with an enclosed impeller, that is
driven by a synchronous magnetic coupling, and meets
dimensional standards of ANSI B73.1.
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 - Two types of rare earth magnets are
available. Neodymium Iron (NdFe), which is used
when pumpage temperatures are less than 250°F
(120°C). For liquid pumpage between 250°F (120°C)
and 425°F (220°C) Samarium Cobalt (SmCo) magnets
are used.
Containment Shell - isolates the pumped liquid from
the atmosphere. Standard material is Hastelloy-C
which provides excellent corrosion and erosion
resistance.
Sleeve Bearings and Thrust Bearings - Goulds
standard bearing material is Pure Sintered Alpha Grade
Silicon Carbide. The sleeve bearings are flexibly
mounted using O-rings.
Impeller - Model 3296 utilizes an enclosed impeller,
hydraulically balanced and keyed to the shaft.
Bearing Frame - the standard configuration is cast
ductile 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 carbon filled teflon non-contacting
labyrinth seal is provided. On the inboard side a lip
seal is used to prevent leakage of oil into the magnetic
drive assembly.
Casing - is top centerline discharge, self venting type
incorporates a fully confined gasket. 150 lb. ANSI
serrated raised face flanges are standard. The 3296 has
been designed such that there is a metal to metal fit
between the casing and frame adapter.
NAMEPLATE INFORMATION
Every pump has 3 Goulds nameplates that provide
information on your pump. The tags are located on the
casing and bearing frame.
Pump Casing Tag - provides information relative to
the pumps characteristics. The format of pump size
information is: Discharge x Suction - Nominal
Impeller Diameter, (ex. 1 x 1
1
2
-6)
Bearing Frame Tag - provides information relative to
the type of magnets being used.
Pump Warning Tag - is permanently fastened to the
bearing frame. It contains precautions to be observed
during the operation, disassembly, maintenance and
reassembly of the pump.
When ordering spare parts you will need to know the
pump model, size, serial number, and the item number
of the required parts. Information can be taken from
the pump casing tag. Item number information can be
found in this manual.
