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.

Piping checklists

Installation
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.

• Avoid death or serious injury. Leaking fluid can cause fire and/or burns. Speed of pump must reach 2000 rpm for 2 pole motors and 1000 rpm for 4 pole motors within 10 seconds or an increase in vibration and rotor deflection and decrease in rotor stability leading to mechanical seal and/or shaft failure and/or pump seizure can occur.
• Never operate the pump without the coupling guard correctly installed.
• Always disconnect and lock out power to the driver before you perform any installation or maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical injury.
• Electrical connections must be made by certified electricians in compliance with all international,
national, state, and local rules.
• Refer to driver/coupling/gear manufacturers installation and operation manuals (IOM) for specific
instructions and recommendations.
• Operating the pump in reverse rotation can result in the contact of metal parts, heat generation, and breach of containment.
• Avoid death or serious injury. Explosion and/or seizure of pump can cause fire and/or burns. Assure balance line is installed and either piped to the pump suction or back to the suction vessel to avoid vaporization of pumped fluid.
DANGER:
Avoid death or serious injury. Leaking fluid can cause fire and/or burns. Assure all openings are sealed off prior to filling pump.
Precautions
NOTICE:
• Verify the driver settings before you start any pump.
• Make sure that the warm-up rate does not exceed 2.5°F (1.4°C) per minute.
You must follow these precautions before you start the pump:
• Flush and clean the system thoroughly to remove dirt or debris in the pipe system in order to prevent premature failure at initial startup.
• Bring variable-speed drivers to the rated speed as quickly as possible.
• If temperatures of the pumped fluid will exceed 200°F (93°C), then warm up the pump prior to operation. Circulate a small amount of fluid through the pump until the casing temperature is within 100°F (38°C) of the fluid temperature. Accomplish this by flowing
Model 3296 EZMAG Installation, Operation, and Maintenance Manual 33
Page 36
Commissioning, Startup, Operation, and Shutdown
fluid from pump inlet to discharge drain (optionally, the casing vent can be included in warm-up circuit but not required). Soak for (2) hours at process fluid temperature.
At initial startup, do not adjust the variable-speed drivers or check for speed governor or over­speed trip settings while the variable-speed driver is coupled to the pump. If the settings have not been verified, then uncouple the unit and refer to instructions supplied by the driver manufacturer.

Pump operation precautions

General considerations
CAUTION:
• Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the suction side since this can result in decreased performance, unexpected heat generation, and equipment damage.
Do not overload the driver. Driver overload can result in unexpected heat generation and equipment damage. The driver can overload in these circumstances:
• The specific gravity of the pumped fluid is greater than expected.
• The pumped fluid exceeds the rated flow rate.
• Do not operate pump past the maximum flow. For maximum flow refer to the pump performance curve.
• Do not overload the driver. Driver overload can result in unexpected heat generation and equipment damage. The driver can overload in these circumstances:
• The specific gravity of the pumped fluid is greater than expected.
• The pumped fluid exceeds the rated flow rate.
• Do not operate pump below hydraulic or thermal minimum flow. For hydraulic minimum flows refer to technical manual and pump performance curve. To calculate thermal minimum flow, refer to HI Centrifugal Pumps for Design and Application ANSI/HI 1.3-2000.
• Make sure to operate the pump at or near the rated conditions. Failure to do so can result in pump damage from cavitation or recirculation.
Operation at reduced capacity
WARNING:
Never operate any pumping system with a blocked suction and discharge. Operation, even for a brief period under these conditions, can cause confined pumped fluid to overheat, which results in a violent explosion. You must take all necessary measures to avoid this condition. If pump becomes plugged shut down and unplug prior to restarting pump.
46 Model 3296 EZMAG Installation, Operation, and Maintenance Manual
Page 49
CAUTION:
• The pump and system must be free of foreign objects. If pump becomes plugged, shut down and unplug prior to restarting pump.
• Avoid excessive vibration levels. Excessive vibration levels can damage the bearings, stuffing box or seal chamber, and the mechanical seal, which can result in decreased performance.
• Avoid increased radial load. Failure to do so can cause stress on the shaft and bearings.
• Avoid heat build-up. Failure to do so can cause rotating parts to score or seize.
• Avoid cavitation. Failure to do so can cause damage to the internal surfaces of the pump.
Operation under freezing conditions
NOTICE:
Do not expose an idle pump to freezing conditions. Drain all liquid that is inside the pump and the cooling coils. Failure to do so can cause liquid to freeze and damage the pump.
Temperature ratings
CAUTION:
Do not operate the pump above the rated temperature range of the magnets. This will weaken or ruin the magnets. The rated temperature is 250°F (121°C) for all sizes.

• Check that the assembly is free from pits and scratches that exceed 0.005 in. (0.127 mm) deep.
• Check that the assembly is free from erosion or corrosion that exceeds 0.005 in. (0.127 mm) deep.
• Check the pump-out vanes for cracks and corrosion.
• Check that the circulation holes are open.
Drive magnet assembly
The magnets are extremely brittle. It is normal to have chips that amount to 10% of the magnet surface per MMPA Standard No. 0100-90.
Perform these checks on the drive magnet assembly (740B):
• Check that the magnets are free of major cracks and extent over 50% of the surface and are free of imperfections that create loose particles.
• Replace the magnets if the magnets and drive magnet carrier were exposed to any pumped fluid.
• Check the drive magnet carrier for cracks and replace if any cracks are found.
• Check the drive magnet carrier hub OD is free from grooves and scratches that are greater than 0.005 in. (0.127 mm).
• Check the magnets for proper bonding to the metal carrier.

Bearing-frame inspection

Checklist
Check the bearing frame for these conditions:
• Visually inspect the bearing frame and frame foot for cracks.
• Check the inside surfaces of the frame for rust, scale, or debris. Remove all loose and foreign material.
• Make sure that all lubrication passages are clear.
• Inspect the inboard-bearing bores. The maximum acceptable bore is 2.836 in. (7.203 cm) for S-group pumps and 3.544 in. (9.002 cm) for M-group pumps.
• Inspect the labyrinth seal O-rings for cuts and cracks.
• Inspect the ball bearings for containment and damage.
• Make sure the gasket surfaces are clean.
• Visually inspect the bearing end cover for cracks and pits.

Bearings inspection

Condition of bearings
Do not reuse bearings. The condition of the bearings provides useful information on operating conditions in the bearing frame.
60 Model 3296 EZMAG Installation, Operation, and Maintenance Manual
Page 63
Checklist
Perform these checks when you inspect the bearings:
• Inspect the ball bearings for contamination and damage.
• Note any lubricant condition and residue.
• Inspect the ball bearings to see if they are loose, rough, or noisy when you rotate them.
• Inspect the silicon carbide bearings for cracks, chips, or excessive wear. If any of these conditions exist, replace the bearing cartridge.
• Investigate any bearing damage to determine the cause. If the cause is not normal wear, correct the issue before you return the pump to service.

Maintenance
NOTICE:
There are several methods you can use to install bearings. The recommended method is to use an induction heater that heats and demagnetizes the bearings.
Only use original spare parts to replace any worn or faulty components. The use of unsuitable spare parts may cause malfunctions, damage, and injuries as well as void the guarantee.
Do not use a flame to heat bearings. This will damage the bearing surfaces. Do not heat the bearings above 275°F (135°C).

Condensed power monitor

Description
ITT offers various power-monitoring devices for specific pump sizes, speeds, and impeller diameters. Power-monitoring devices are designed to protect pumps from:
• Dry-running
• Running against a closed discharge valve
• Running outside of the recommended operating region
Power monitors were designed to detect power relative to load, which is a linear function, as opposed to measuring amperage relative to load, which is a parabolic function. The linear characteristic of measuring power vs. load enhances sensitivity at low-power conditions where increments in power are critical. This figure shows a comparison of power measurements vs. amperage measurements. A properly adjusted and installed power monitor is an insurance policy for securing extended pump life.
Figure 15: Power vs. amperage measurements
Since the current curve is so flat, load changes are difficult to detect when you measure only the current in this range. If you misread these changes, then nuisance tripping or a dry running pump can result. If you measure power as well, then this problem is eliminated.
Power draw measuring
Power monitors can be strategically calibrated to protect your pump by measuring the power draw from any of these conditions:
• Dry running
• Closed discharge valve
• No prime
• Inadequate suction conditions/plugged suction
• Cavitation
• Air lock
• Decoupled magnets
• Solidified, plugged, or frozen discharge line
• Fluctuating viscosities, precipitation, or coagulation
• Broken or damaged shaft
Model 3296 EZMAG Installation, Operation, and Maintenance Manual 89
Page 92
Other Relevant Documentation or Manuals
• Broken or damaged coupling
• Jammed impeller
• Bad bearings
• Rapid cycling
The power draw at each of these conditions can be simulated in a plant test or estimated through calculations or interpolations from the pump performance curve. By defining these dangerous power fluctuations, appropriate calibration of the power-monitoring unit prevents avoidable pump failures. This figure shows a typical power evaluation recorded from a common centrifugal pump electric motor.
1. The pump is in operation.
2. The valve is closing.
3. The valve is opening.
4. There is no fluid being pumped.

Calibration tips
Contact your ITT representative for assistance and power analysis for your specific system. For further details and evaluation of power monitoring units, a comprehensive power monitor user guide is available from ITT.
Use these tips to assist you when you select and calibrate power monitors:
• Read your power monitor installation instructions and wiring diagram before you attempt to calibrate the unit.
• Understand the recommended operating envelope of your pump provided by ITT.
• Understand the requirements and limitations of your system.
• Understand the full range of your operating duty, including power requirements at the rated minimum and maximum flow conditions.
• Identify potential failures that would be characteristic of your specific process and pump type.
• Understand the power scope and torque scope of the selected electric motor.
• When feasible, further define your operating range to run as close to best efficiency point (BEP) as practical.
• Select either a single trip unit or dual trip unit as practical for your specific system. A dual trip unit is recommended for the 3296 EZMAG. Always use a low setting in order to protect against dry run. A high setting detects if an upset condition has occurred. This results in bearing damage.
• Set a low-power trip point at the required power draw when operation is at the recommended minimum flow of the manufacturer or higher, but less that the normal operating point.
• Set a high-power trip point at the required power draw when operation is at the recommended maximum flow of the manufacturer or lower, or at the flow rate that will prevent cavitation.

Other Relevant Documentation or Manuals
• When using dual trip power monitors, select high and low trip points designed to protect your specific system within the recommended pump operating region that is defined by ITT. This method creates boundaries for a safe pump operating envelope.
• Set the nuisance trip feature for each power trip. Set the nuisance trip device to an interval that allows the system to experience momentary fluctuations in power draw. Set it during an appropriate time-frame that prevents the pump from experiencing excessive heat or dangerous operating conditions.
• Set the delay timer for start-up conditions that allow the system to come to normal operating power within a time-frame that maximizes protection of your pump.
• For variable speed operation, consult ITT or the power monitor manufacturer for appropriate auxiliary devices that are designed for operating at multiple speeds or fluctuating frequencies.
• Select an electrical enclosure that is suitable for the operating environment, or install the unit in an appropriate electrical panel.
• Do not activate the manual override of the power monitor until a thorough examination of the source of the problem is defined and corrected.
• Investigate and select power monitor features that are most suitable for your particular application and plant safety.
