STANDARD MAINTENANCE

Maintenance and replacement of parts subject to wear
on Fluid-o-Tech magnet drive gear pumps should only be
done by a technician certified by Fluid-o-Tech. Periodic
cleaning of the hydraulic circuit and filters is advisable
in order to avoid cavitation and premature wear of the
internal components.

MAGNET DRIVE GEAR PUMPS
MG, MK, MS AND PG SERIES

INSTALLATION

The pump should be installed exclusively by authorized
staff. Handle with care.
WARNING
The flange must be handled with
care and should not be grasped with
tongs or vices, since this could cause
misalignment of the magnets and
damage of the pump.
For food applications the pumps (even
when NSF listed) need to be sanitized 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. In order to avoid any accidental ingress
of solid matter which might damage the internal
components of the pump, it is recommended
removing the two protection caps placed on the inlet
and outlet ports of the pump only immediately before
mounting the fittings and the pipework.
If continuous operation is required, the pump should
be mounted in a well ventilated environment 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, do not allow
any to enter the pump.
It is advisable to use stainless steel or plastic fittings.
When substituting just the pump-head, it is necessary
to ensure that the model number of the new pump is
identical to the pump to be changed. Exchanging the
pump for a model of different capacity may damage
the system, the motor and the pump itself.
The hydraulic circuit should be carefully flushed before
starting the pump.

WIRING THE MOTOR TO THE POWER SUPPLY

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

MOTOR SELECTION

When the motor is not supplied with the pump it
is necessary to verify that the motor dimensions
and specifications are in line with Fluid-o-Tech
recommendations. Fluid-o-Tech gear pumps need
a motor running at a speed between 800 and 5000
rpm. The flow rate is proportional to the motor speed.
The continuos max torque must be lower than 0.1 Nm
with ferrite-ferrite magnet coupling. Higher torque can
be attained with other types of magnets.
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 Loosen the set screw until it no longer protrudes into
the bore where the shaft will be inserted.
3 Place the magnet on the tool AT152 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 as to make the extraction of the
magnet difficult. The pin should not be scratched by
the set screw when extracting the shaft.
