INSTALLATION
The pump has to be installed exclusively by authorized
staff. Handle with care.
WARNING
For food applications the pumps (even when NSF
listed or WRAS approved) need to be sterilized by
circulating water at 80 °C (176 F) for at least 20
minutes. The water used for this operation must
not be reused, either during the sterilization or
later, but must be discharged.
For speed higher than 2500 rpm the internal
pins must be in PTFE instead of stainless steel.
Stainless steel pins will damage the vane and
cause the pump to fail. The circuit should be
carefully flushed before starting the pump.
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/TH series rotary vane pumps look identical
in their exterior aspect, although the flow rates are
different. For this reason, in case of replacement, you
should make sure that the new pump is compatible
with the previous model you have, giving close
attention to the flow rate, pressure and mounting.
Changing the pump with a model of different capacity
may damage the system and the pump itself.
If continuous operation is needed, the unit 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

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

electrical data printed on the motor plate, with
particular regard to voltage, frequency and current.
• The power supply should be switched off during

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.

• The motor rotation must be clockwise (looking the
motor in front). 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
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 necessary to put, 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, they should be installed only 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. If the pump is
equipped with a bypass valve, the valve will act, in case
of accidental overpressure, to limit the pressure, thanks
to an internal recirculation of the fluid.
The bypass valve is a relief valve and must not be
used as a flow regulator. If used as a flow regulator,
the water in excess will recirculate inside the pump
heating and encouraging the deposit of limestone
on the pump components. The maximum differential
pressure should be at least 3 bar (43 psi) lower than
the bypass valve setting in order to avoid operation
with the bypass valve open. The maximum differential
pressure must not exceed 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. 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.
