Product Description
Product Description
General description
Model 3296 EZMAG
The Model 3296 EZMAG is a sealless centrifugal pump with an enclosed impeller that is driven
by a synchronous magnetic coupling. Model 3296 EZMAG meets the dimensional standards of
ANSI B73.1.
Casing
The casing is top centerline discharge and is self-venting. It incorporates a fully-confined
gasket with ANSI Class 150 flanges that are serrated and raised-faced. ANSI Class 300
flanges that are serrated and raised-face are optional. The 3296 EZMAG is designed to have a
metal-to-metal fit between the casing and the backplate.
Magnetic coupling
The magnetic coupling is a coaxial synchronous type that uses rare earth magnets. 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.
Magnets
Two types of rare earth magnets are available:
• Neodymium Iron (NdFe) is used when pumped liquid temperatures are less than 365°F
(180°C).
• Samarium Cobalt (SmCo) is used when pumped liquid temperatures are between 365°F
(180°C) and 536°F (280°C).
Containment shell
The containment shell isolates the pumped liquid from the atmosphere and is constructed from
Hastelloy-C.
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
The 3296 EZMAG uses an enclosed impeller that is hydraulically-balanced and keyed to the
shaft.
Bearing frame
The standard configuration is cast iron with ball bearings that are flood oil–lubricated. Greasedfor-life bearings systems are available as an option. Bronze bearing isolators are provided for
protection and reliability of the bearings and the lubricant.
Nameplate information
Important information for ordering
Every pump has nameplates that provide information about the pump. The nameplates are
located on the casing and the bearing frame.
When you order spare parts, identify this pump information:

Grout the baseplate
Required equipment:
• Cleaners: Do not use an oil-based cleaner because the grout will not bond to it. See the
instructions provided by the grout manufacturer.
• Grout: Non-shrink grout is recommended.
1. Clean all the areas of the baseplate that will come into contact with the grout.
2. Build a dam around the foundation.
3. Thoroughly wet the foundation that will come into contact with the grout.
4. Pour grout through the grout hole into the baseplate up to the level of the dam.
When you pour the grout, remove air bubbles from it by using one of these methods:
• Puddle with a vibrator.
• Pump the grout into place.
5. Allow the grout to set.

Fastening
WARNING:
• Only use fasteners of the proper size and material.
• Replace all corroded fasteners.
• Make sure that all fasteners are properly tightened and that there are no missing fasteners.
General piping checklist
Precautions
CAUTION:
• Never draw piping into place by using force at the flanged connections of the pump. This can
impose dangerous strains on the unit and cause misalignment between the pump and driver. Pipe
strain adversely affects the operation of the pump, which results in physical injury and damage to
the equipment.
• Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the
suction side. This action can result in decreased performance, unexpected heat generation, and
equipment damage.
CAUTION:
Flange loads from the piping system, including those from the thermal expansion of the piping, must not
exceed the limits of the pump. Deformation can result in contact with rotating parts, which can result in
excess heat generation, sparks, and premature failure.
Piping guidelines
Guidelines for piping are given in the Hydraulic Institute Standards available from the Hydraulic
Institute at 9 Sylvan Way, Parsippany, NJ 07054-3802. You must review this document before
you install the pump.
