It’s recommended pulling out the two protection sponge
caps placed on the inlet and outlet ports of the pump only
immediately before mounting the fittings and the pipes, in
order to avoid the incidental entrance of any solid
estraneous object which might damage the internal
components of the pump.
The TM series rotary vane pumps look identical
in their exterior aspect, although the flow rates are
different. For this reason, when replacing just the pump,
it is necessary to check the model of the new pump.
Changing the pump with a model of different capacity
may damage the system and the pump itself.
If continuous operation is needed, the pump has to be
mounted in an airy space in order to dissipate the heat
produced by the motor. To avoid vibrations of mechanical
parts and noise, it is advisable to mount the motor with
rubber shock-absorbing supports.
Particular care must be taken when connecting the pump
with fittings in order to avoid leaks.
If a sealing fluid or Teflon tape is used, make sure to avoid
any quantity of it to fall into the pump.

ASSEMBLING THE MAGNET
ONTO THE MOTOR SHAFT
]
MOTORS WITH FLAT SHAFT (“D” TYPE)
1. Tighten the set screw in its seat in the magnet
holder until it protrudes from the bore of the brass
insert in order to verify that there are no imperfections
in the thread which might stop the set screw before
it is able to block the magnet on the rotor shaft.
2. Untighten the set screw until it does not protrude
any longer into the bore where the shaft will be
inserted.
3. Place the magnet on the tool AT126/A with the bore
where the set screw sits in correspondence with the
flat surface of the “D” pin (fig. 1).
4. Tighten the set screw until it touches the pin, but do
not tighten so much to make the extraction of the
magnet difficult. The pin should not be scratched by
the set screw when extracting the shaft.
5. Remove the magnet and place it on the motor shaft.
In such conditions the set screw, protruding slightly
from the internal diameter of the bore in the brass
bushing, prevents an incorrectly oriented assembling
onto the motor shaft.
6. Place the unit vertically on the bench with the
magnet facing downwards (see fig. 2) to place the
magnet in the correct position.
Tighten the set screw with a max torque of 2.0 Nm.
MOTORS WITH SHAFT KEY SEAT AND
“TMA”/ “TMAS” SERIES DRIVING MAGNETS
1. Tighten the set screw in its seat in the magnet holder
until it protrudes from the bore of the brass insert in
order to verify that there are no imperfections in the
thread which might stop the set screw before it is
able to block the magnet on the rotor shaft.
2. Untighten the set screw until it does not protrude
any longer into the bore where the shaft will be
inserted.
3. Remove the shaft key from the motor shaft.

4. Predispose the magnet on the motor shaft paying
attention, in case the magnet is of TMA or TMAS
series, not to tighten the set screw close to the shaft
key seat. In case the magnet is of TMAS-C series
please see the paragraph: “motors with shaft key
seat and “TMAS-C” series driving magnets”.
5. Position the unit vertically: a) on the test bench for
TMA series magnets in order to have the magnet
and the motor adapter on the same level or b) on
tool AT155/1 for TMAS series magnets in order to
assemble the magnet in the correct position.
Tighten the set screw with a max torque of 2.0 Nm.
MOTORS WITH SHAFT KEY SEAT AND
“TMAS-C” SERIES DRIVING MAGNETS
1. Tighten the set screw in its seat in the magnet holder
until it protrudes from the bore of the brass insert in
order to verify that there are no imperfections in the
thread which might stop the set screw before it is able
to block the magnet on the rotor shaft.
2. Untighten the set screw until it does not protrude any
longer into the bore where the shaft will be inserted.
3. Make sure the shaft key is in its seat on the motor shaft.
4. Align the shaft key with the relevant seat in the
magnet bore and slide the magnet on the motor shaft.
5. Position the unit vertically on tool AT155/1 with the
magnet facing downwards in order to set the
magnet in the correct position (see fig. 2).
Tighten the set screw with a max torque of 2.0 Nm.
[WIRING THE MOTOR TO THE POWER SUPPLY]
• The power supply must be consistent with the
electrical data printed on the motor plate, with
particular regard to voltage, frequency and current.
• The power supply should be switched off during
installation.
• The motor rotation must be clockwise (looking
the motor in front).

“D” shaft or shaft key seat
AT 155/1
Place the unit vertically on tool AT155/1 in order
to assemble the magnet in the correct position.
If operated counterclockwise, the pump won’t work.
In case the rotation is counterclockwise, proceed
according to the scheme generally enclosed in the
electrical wiring box.
The pumps – although identical in their aspect – may
have GAS or NPT threaded ports. The thread of the
fitting should match the thread of the pump port. If the
pump has GAS threads the sealing is provided by an
o-ring which is pressed against the flat surface of the port.
With the NPT thread, the sealing is provided by the contact
between the threads. In this case a few turns of PTFE tape
around the fittings are necessary. Do not exceed in using
PTFE tape as pieces of it may fall into the pump (especially
on the Inlet side) and cause the pump to fail.
The use of pipe dope (liquid sealant) should be avoided.
A particular care is needed while mounting the fittings,
to avoid liquid leaks.
Hold the pump with a wrench in the area marked with
the arrows indicating the inlet-outlet ports and the
rotation sense, without over-tightening. Maximum
torque recommended to tigthten the fittings is 15 Nm.
It is suggested to use aluminium sheet on each side
of the pump to avoid damage to ports.
Do not use the motor as pump support when
tightening the fittings, in order to avoid a possible
misalignment and stress of the shafts.
If the pump is made of stainless steel the fittings have
to be made of stainless steel or plastic, not in brass, to
avoid problems of corrosion.
[OPERATING CONDITIONS]
Make sure that the pumped fluid is compatible
with the materials of the pump.
The Fluid-o-Tech pumps are designed to handle clean
water at ambient temperature. Any other fluid and/or
operating condition needs to be tested and approved
by the customer and verified by Fluid-o-Tech.
The maximum liquid temperature is 70 °C (158 °F).
It is strongly recommended to use, especially for the inlet
port, piping with internal diameter 10 mm (3/8”).
This will avoid cavitation and consequent failure of the pump.
The piping on the outlet port has to be resistant to
20 bar. It is also recommended before the pump a
filter capable of keeping out particles larger than 10 µm
which could cause fast wear of the internal
components, and with a surface area big enough, in
order not to cause hydraulic losses in the circuit.
It is also important checking periodically the filter
cartridge.
In order to keep the filter under control, it is advisable
to install a vacuum gauge before and after the filter.
In case the vacuum increases more than 0.1 bar, the
cartridge should be cleaned or changed.
For a long life of the pump, the pumped fluid must not
contain solid particles.
Although the magnet drive rotary vane pumps are
self-priming, they should operate under water head, in fact
dry running causes fast wear of the internal components.
A dirty filter or an insufficient supply of water could
cause cavitation and fast wear of the internal
components of the pump.
If the line is subject to scarce pressure or flow it is
necessary to fit a pressure/level switch before the
pump in order to switch the motor off.
It is also necessary to protect the system from incidental
overpressures with safety devices such as a pressure relief
valve or a pressure switch connected to the motor.
It is not advisable to install solenoid valves in the
circuit; however, if needed, the soleinoid valve should be
installed after the pump. The internal diameter should be
well sized to the pump capacity.
In order to avoid pressure strokes it is necessary to
operate the solenoid valve only after the pump
stopped, allowing a few seconds to go by after
the motor has been switched off.
Soleinod valves before the pump are to be avoided at all
times. If the pump is equipped with a relief valve (by-pass),
the valve will act, in case of accidental overpressure, to limit
the pressure, thanks to an internal recirculation of the fluid.
The relief valve is not and must not be used as
a flow regulator.
If used as a flow regulator, the water in excess will
recirculate inside the pump through the relief valve
and the pump will fail.
The maximum differential pressure should be at least
3 bar (~45 psi) lower than the relief valve setting in
order to avoid operation with the relief valve open.
The maximum differential pressure must not exceed
in any case 16 bar (230 psi).
Thanks to the magnetic coupling the pump does not
need a mechanical seal in order to prevent leakage.
This eliminates the problems connected to the use of a
mechanical seal.
However the maximum pressure depends on the pump
model and it decreases with the increase of the flow rate.
Beyond the values specified in the graphs indicated at
page 4 of this leaflet (continous line for pumps with
TMA Series driving magnets - intermittent line for
pumps with TMAS Series driving magnets) being the
transmittible torque limited by the magnet, the coupling
between the motor and the pump is not guaranteed
and therefore the pump might stop.
In order to re-establish the coupling it is sufficient to
stop the motor, wait until complete stop and then
restart the motor again. The sum of the inlet and outlet
pressure must not exceed 20 bar/290 psi in any case.
[STANDARD MAINTENANCE]
The Fluid-o-Tech magnet drive rotary vane pumps
maintenance and replacement of parts subject to wear
have to be done by a qualified technician. Periodic
cleaning of the circuit and filters is advisable in order to
avoid cavitation and wear of the internal components.
[CERTIFICATIONS]
The pump itself, without the motor, is not to be considered
as a machine, but only a component, therefore the mark
“CE” is not applicable. When the pump is assembled with
a motor, the complete pump-motor unit is instead
considered as a machine and supplied with the mark “CE”.
In this case, the unit satisfies the requirements of the
following Directives: 89/366/CEE related to Electromagnetic
Compatibility - EMC, 73/23/CEE related to Electrical
Material intended to be used in potentially explosive
enviroments - DTB and 94/9/CE related to Equipments and
Protection Devices intended to be used in potentially
explosive enviroments - ATEX. A conformity declaration
may be requested to Fluid-o-Tech to state the essential
compliances with the above mentioned Directives.
TMOT…A and TMSS…A series pumps are NSF listed.
Product in conformity with the D.M. 174/2004.
