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 fittings and connections are airtight to
reduce the rist of cavitation which may damage the pump.
INSTALLATION: Months of careful planning, study, and

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 floor. Multiple installations with conflicting
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.
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 fluids 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 fluid. 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 configuration, running dry on a regular
basis can shorten the overall mean time between failure
(MTBF) of the pump.

CONTROLS: All pumps should be outfitted with the
appropriate safety shut off 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 flow meter be used to monitor the pump's
performance over time.
PUMP
DISCHARGE:
Be
capabilities of the pump meet the required pressure to
overcome the friction loss across the discharge piping,
filters 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
fittings 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 fittings.
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.
When pumps are installed in applications involving
flooded 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:
not be submerged for use.
T-MAG™ PUMPS ARE CAPABLE OF PASSING SOLIDS
BELOW 50μ (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 fitted T-MAG™ Mag-
Drive pumps are suited for limited dry run conditions
only. Other materials such as Rulon® and SSIC fitted
pumps are not suitable for dry run conditions.
