The pump’s maximum operating
pressure will change with variations in operating
temperature and size of the pump. Please refer
to table below for the recommended maximum
operating pressures for T-MAG™ pumps.
Operating a T-MAG™ pump below the
minimum ow rates shown below may result in a
signicant rise in temperature within the interior
of the pump. Operation of the pump below these
minimum levels may also result in increased radial
and axial forces on the shaft, bushing and impeller
assembly. These resulting conditions may aect the
pump’s performance and service life.
Do not run the pump without uid
for extended periods of time. Depending upon
application conditions, dry-running the pump may
cause the temperature of the internal components to
rise, resulting in damage to the pump internals.
When selecting a pump for a specic
application be sure to consider the concentration
of the uid being pumped. Changes in uid
concentration may aect viscosity and specic
gravity. Other physical properties, such as
corrosiveness, may also change with variations in
uid concentration.

FIGURE 1: PUMP LIQUID END
Fluid is moved by a centrifugal pump through the use of centrifugal
force. Fluid is taken into the center of the impeller through the inlet
connection. Most centrifugal pumps prefer a positive inlet pressure
to prevent cavitation (lack of enough positive inlet pressure to
prevent liquid vaporization). This fluid is then caught by the vanes
of the impeller as it spins. This rotation of the fluid mechanically
by the vanes “throws” the fluid to the outside of the impeller and
toward the discharge port of the liquid end of the pump. This
mechanical movement of the fluid creates the discharge pressure
of the pump. Variables like inlet fluid supply pressure, impeller
diameter, motor horsepower and closed face versus open face all
effect the flow and pressure of the pump. Each of these variables
can be manipulated to achieve a desired flow and/or pressure.

FIGURE 2: PUMP MAGNETIC DRIVE
A magnetic drive pump uses a balanced magnetic field to create
the rotation of the fluid impeller. Unlike a traditional centrifugal
pump which has a direct drive connection between impeller and
motor, a mag-drive pump eliminates the direct drive mechanism
and replaces it with a magnetic field. An outer magnetic bell
housing is mounted on the end of the pump shaft. This outer bell
is aligned on the outside of the rear casing. The pump impeller
is connected to a smaller magnet assembly and rides on an
internal shaft and bushing assembly. (The liquid end par ts are all
isolated within the fluid head of the pump without the need for a
mechanical seal.) The smaller magnet assembly is mounted within
the center of the magnetic field of the outer bell housing. Although
these two magnet assemblies are separated by a fluid barrier, the
magnetic fields are aligned. When the pump motor is started the
outer bell housing begins to rotate. As the outer bell rotates, the
rotating magnetic field effects the inner impeller magnet. As the
two magnets begin to turn together, the impeller begins turning
and displacing fluid.
Note: The total length & weight of the pump will differ depending on the brand of the motor.

Section 6
SUGGESTED INSTALLATION
T-MAG™ pumps are designed to meet the performance
requirements of even the most demanding pumping
applications. They have been designed and manufactured
to the highest standards and are available in a variety of
liquid path materials to meet your chemical resistance
needs. Refer to the performance section of this manual
for an in-depth analysis of the performance characteristics
of your pump. The suction pipe size should be at least
the equivalent or larger than the diameter size of the
suction inlet on your T-MAG™ pump. The suction hose/
pipe must be non-collapsible. Discharge piping should
also be the equivalent or larger than the diameter of the
pump discharge which will help reduce friction losses. It
is critical that all ttings and connections are airtight to
reduce the rist of cavitation which may damage the pump.
INSTALLATION: Months of careful planning, study, and
selection eorts can result in unsatisfactory pump
performance if installation details are left to chance.
Premature failure and long term dissatisfaction can be
avoided if reasonable care is exercised throughout the
installation process.
LOCATION: Noise, safety, and other logistical factors
usually dictate where equipment will be situated on the
production oor. Multiple installations with conicting
requirements can result in congestion of utility areas,
leaving few choices for additional pumps. Within the
framework of these and other existing conditions, every
pump should be located in such a way that the 8 key
factors are balanced against each other to maximum
advantage.
ACCESS: First of all, the location should be accessible. If
it’s easy to reach the pump, maintenance personnel will
have an easier time carrying out routine inspections and
adjustments. Should major repairs become necessary,
ease of access can play a key role in speeding the repair
process and reducing total downtime.
CONTROLS: All pumps should be outtted with the
appropriate safety shut o and controls to meet the
local, state or federal requirements for the application in
the area the pump is being used. To better understand
the performance of the pump it is recommended that
gauges be placed on the inlet and discharge lines of the
pump, isolation gauges be installed for isolation and
repairs and a ow meter be used to monitor the pump’s
performance over time.
PUMP DISCHARGE: Be sure that the discharge
capabilities of the pump meet the required pressure to
overcome the friction loss across the discharge piping,
lters and valving. Do not close the downstream
isolation valve of the pump while in operation. Doing so
will cause the pump head to overheat and may damage
the internals of the pump.
PIPING: Final determination of the pump site should not
be made until the piping challenges of each possible
location have been evaluated. The impact of current
and future installations should be considered ahead of
time to make sure that inadvertent restrictions are not
created for any remaining sites.
The best choice possible will be a site involving
the shortest and straightest hook-up of suction and
discharge piping. Unnecessary elbows, bends, and
ttings should be avoided. Pipe sizes and type should
be selected to keep friction losses within practical
limits. All piping should be supported independently of
the pump. In addition, the piping should be aligned to
avoid placing stress on the pump ttings.
Flexible hose can be installed to aid in absorbing the
forces created by the natural vibration of the pump. If the
pump is to be bolted down to a solid location, a mounting
pad placed between the pump and the foundation will
assist in minimizing pump vibration.
ELECTRICAL SUPPLY: Every pump location should have
all power lines, conduit and switches mounted in such
a way as to avoid any risk or hazard to the user or work
area. Keep in mind that while pumping some uids it
is required to ground the pump to prevent discharge of
any static buildup. For best results, ensure a licensed
professional performs any necessary installation work.
PUMP INLET: To optimize pump life it is important to
install the pump in a position that will ensure a constant
supply of process uid. Running the unit dry will cause
cavitation which could result in unnecessary vibration.
This vibration can result in internal component damage
that could diminish the life of the pump. Also, although
the pump is designed to run dry without damage in the
carbon / ceramic conguration, running dry on a regular
basis can shorten the overall mean time between failure
(MTBF) of the pump.
13
When pumps are installed in applications involving
ooded suction or suction head pressures, a gate valve
should be installed in the suction line to permit closing
of the line for pump service.
SUBMERSIBLE APPLICATIONS: T-MAG™ pumps can
not be submerged for use.
T-MAG™ PUMPS ARE CAPABLE OF PASSING SOLIDS
BELOW 50 (microns), ALTHOUGH ANY SOLIDS WITHIN
THE PROCESS STREAM OF A T-MAG™ PUMP COULD
WEAR CRITICAL COMPONENTS.
This wear will diminish performance or cause failure
of the pump. Standard carbon tted T-MAG™ MagDrive pumps are suited for limited dry run conditions
only. Other materials such as Rulon® and SSIC tted
pumps are not suitable for dry run conditions.

SUGGESTED OPERATION & MAINTENANCE
OPERATION: Pump discharge rate can be controlled by
modifying the pump impeller, changing to a different motor
power rating or through a “turndown” of the motor RPMs.
Pump discharge rate can also be controlled by throttling
the pump discharge by partially closing a valve in the
discharge line of the pump. Do not close the discharge
valve all the way as this may cause a heat buildup in the
liquid end of the pump and damage the pump internals.
MAINTENANCE AND INSPECTIONS: Since each application
is unique, maintenance schedules may be different for
every pump. Frequency of use, line pressure, viscosity and
abrasiveness of process fluid all affect the parts life of a
T-MAG™ pump. Periodic inspections have been found to
offer the best means for preventing unscheduled pump
downtime. Personnel familiar with the pump’s construction
and service should be informed of any abnormalities that
are detected during operation.
RECORDS: When service is required, a record should be
made of all necessary repairs and replacements. Over a
period of time, such records can become a valuable tool
for predicting and preventing future maintenance problems
and unscheduled downtime. In addition, accurate records
make it possible to identify pumps that are poorly suited
to their applications.
TROUBLESHOOTING
Motor will not rotate when system is turned on.
1. Ensure that motor is connected to power supply and
that supply switch is installed properly.
2. Inspect motor to ensure that is it is operating condition
and does not require service.
3. Ensure that the power lines have been properly
connected for the supply voltage and Hz.

CAUTION: Before any service is performed on a T-MAG™ pump, all electrical lines
must be disconnected and all process fluid drained from the pump. DO NOT open the
pump connections if process fluid pressure remains inside the pump. Use the liquid
end drain plug to drain remaining fluid from the impeller chamber.
NOTE: The model shown in this example represents all five sizes of T-MAG™ magdrive pumps.
Step 1
Before disassembly, mark motor,
mounting bracket and pump head to
ensure proper configuration during
reassembly.
21
Step 2
Using a metric wrench, remove all
liquid end bolts from pump head.
Step 3
Carefully remove the outer liquid
casing from the central mounting
bracket. Do not twist or rock the
liquid end to assist with removal.
This will place unnecessary torque
on the shaft and may damage it.
Page 24
PUMP DISASSEMBLY
Step 4
Remove and inspect outer casing oring for damage or wear. Replace as
necessary.
Step 5
Carefully remove the impeller/
magnet assembly. Use caution not
to pinch fingers as the impeller will
show resistance being removed due
to the magnetic field of the outer
magnet.
Step 6
Remove the rear casing of the liquid
end from the mounting bracket.
Inspect for wear inside or out, as
this may be a sign of misalignment
of the impeller or outer magnet.
Step 7
Remove the bolts holding the
mounting bracket to the motor.
Use caution when removing as the
motor is heavy and may tip causing
injur y.
22
Step 8
Carefully remove the mounting
bracket from the motor, exposing
the outer magnet.
Step 9
If it is necessary to remove the outer
magnet from the motor, use a hex
wrench to remove the two (2) set
screws from the shaft end. NOTE:
The outer magnet adjustment
screws on some T-MAG™ MagDrive pumps must be accessed
through the adjustment port located
under the mounting bracket.
Page 25
PUMP DISASSEMBLY
Step 10
Once the set screws are removed,
inspect the shaft keyway and bell
housing for wear or damage and
replace as necessary.
Step 11
Carefully remove the pump shaft
from the front shaft support.
DO NOT twist or flex the shaft to
assist removal. Pull vertically to free
the shaft from the front support.
Step 12
Gently lift up on the front buffer
to free it from the inlet por t.
DO NOT use any tools for removal
as this may damage the part forcing
replacement.
Step 13
Gently lift up on the front shaft
suppor t to free it from the pump
inlet port. DO NOT use any tools
as this may damage the part
forcing replacement.

CAUTION: Before reassembling a T-MAG™ pump, carefully read the following
instructions and special procedures. Failure to do so may result in premature
failure of the pump components or damage to an individual part making assembly
impossible.
NOTE: The steps shown in this example represents all five sizes of T-MAG™ magdrive pumps. The steps shown are not necessarily in order of reassembly of the
pump.
Tip 1
When installing the shaft into the
front shaft support, ensure that the
trimmed end of the shaft fits cleanly
into the support. Gently inset shaft
by hand or using a hand press.
Always use a towel or rag to protect
the shaft.
24
Tip 2
When installing the front wear ring
into the front buffer use a hand
press to ensure that the wear ring is
evenly inserted. Failure to ensure a
level wear surface will damage the
impeller wear ring and reduce the
life of the pump.
Tip 3
Before installing the flanges and orings on the inlet and discharge ports,
spray the o-rings with a lubricant to
ease installation. Confirm lubricant
used is compatible with all pump
materials and process application.
Page 27
REASSEMBLY HINTS & TIPS
Tip 4
When completing the final
tightening rotations on the flanges,
use a strap wrench or a soft jawed
vise to prevent damage to the
flanges.
Tip 5
Use a hand press to carefully insert
the shaft and front shaft support
into the front casing.
Tip 6
Align the assembled front buffer
assembly into the front casing by
carefully aligning the “feet” of the
buffer with the three “fins” of the
casing. This will prevent rotation or
misalignment of the buffer during
operation.
Tip 7
Before installing the impeller/
magnet assembly, use an adhesive
tape to remove ALL metal fragments
or debris that may be on the outside
of the magnet housing. Failure to
do so will result in premature wear
of the rear casing of the pump.
25
Tip 8
Complete the assembly of the wet
end of the pump by placing the rear
casing with o-ring installed.
Tip 9
When installing the outer magnet
onto the motor shaf t, use a wood
block or plastic buffer to prevent
damage to the magnets. Never use
a hammer directly on the magnet
assembly.
Page 28
REASSEMBLY HINTS & TIPS
Tip 10
For proper alignment of the
magnetic field, align the end of the
shaft flush with the inside bottom of
the magnet assembly.
Tip 11
Before installation of the previously
assembled liquid casing of the
pump, use an adhesive tape to
remove ALL metal fragments or
debris that may be on the outside of
the magnet housing. Failure to do
so will result in premature wear of
the rear casing of the pump.
