SAFETY WARNINGS
Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.
WARNING
A pump is a pressure vessel with rotating parts that can be hazardous. Any pressure vessel can explode,
rupture, or discharge its contents if sufficiently over pressurized causing death, personal injury, property
damage, and/or damage to the environment. All necessary measures must be taken to ensure over
pressurization does not occur.
WARNING
Operation of any pumping system with a blocked suction and discharge must be avoided in all cases.
Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage and
result in a violent explosion. All necessary measures must be taken by the end user to ensure this condition is
avoided.
WARNING
The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pump
and eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, but
are not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.
WARNING
Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for
disassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers
and/or impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly
expand and result in a violent explosion and injury.

PUMP DESCRIPTION
The Model 3296 EZMAG is a sealless centrifugal pump
with an enclosed impeller that is driven by a synchronous
magnetic coupling. It meets the dimensional standards
outlined in 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 365°F (180°C). For liquid
pumpage between 365°F (180°C) and 536°F (280°C)
Samarium Cobalt (SmCo) magnets are used as part of the
high temperature option.
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. Dryguard™ bearings are available for dry-run
protection.
Impeller - Model 3296 EZMAG utilizes an enclosed
impeller, hydraulically balanced and keyed to the shaft.
Bearing Frame - the standard configuration is cast iron
with flood oil lubricated ball bearings. Greased-for-life
bearings systems are available as an option. For protection
and reliability of the bearings and the lubricant, bronze
bearing isolators are provided as standard.
Casing - is top centerline discharge, self venting type
incorporates a fully confined gasket. 150 lb. ANSI serrated
raised face flanges are standard. The 3296 EZMAG has
been designed such that there is a metal-to-metal fit
between the casing and backplate.
