All the components must be metallic and conductive
(adapter included). Proper earthing on the whole
equipment is required.
Pump operation involves the risk of producing an
electrostatic charge in flowing liquids. The user should
take measures according to IEC TS 60079-32-1. Only
liquids with a high conductivity (> 1000 pS/m) can be
used.
In order to prevent temperature increase, avoid working
with:
- closed outlet port;
- direct return of liquid from outlet to inlet side of the
pump.
INSTALLATION AND MAINTENANCE
Please refer to the instruction manual and follow the
instructions available for the installation (paragraph
“Assembling the magnet onto the motor shaft”) using the
tool AT-152_....
During the operation of assembling the magnet onto the
motor shaft, verify that noises and/or vibrations are not
present when the motor shaft rotates.
A dedicated tool is available: AT- 628_..., please refer to
the table below for the various configuration.
Remove the AT-628_... tool and assembly the pump,
verify again that noises and/or vibrations are not present
when the motor shaft rotates. Perform a periodical check
of the alignment of the pump and the external magnet.
Perform a periodical check of the pump performance
(every 1000 h of operation), if the decrease in
performances is higher than 20% it is needed to replace
the pump. Proper earthing of the whole equipment
(motor + adapter + pump) is required. Earthing terminals
should be provided on the motor, if not possible, apply
earthing connection on another component of the group.
Verify periodically the proper earthing of the whole group.
The adapter covers rotating parts such as external
magnet and motor shaft, all the open holes in the adapter
must be plugged.
Verify the chemical and thermal compatibility of the fluid
with the pump materials. Periodically check that no
leakages are present.
Periodically clean the equipment, also the internal
part of the adapter/coupling, the pump should then
be accessible for maintenance and inspection.

• Normal wear and tear is not covered by the present
warranty
The adjustment or replacement of defective parts made
under this warranty will not extend the original warranty
period. The Purchaser/User is responsible for the
disposal or recycling of the product at end of its use or
lifetime. For more information on proper disposal method,
please contact Fluid-o-Tech Customer Care.
CERTIFICATIONS
NSF listed pumps available for drinkable liquids. For the
model details, please refer to the official NSF website
(direct link available on www.fluidotech.it)
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”. Please refer to Fluid-o-Tech
declaration of conformity, which may be requested to
state the essential compliances with the Directives.
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.
ATEX CERTIFICATIONS FOR
MG, MK AND MS PUMP SERIES
GENERAL
This manual contains important and useful information
on protection against the risks in potentially explosive
atmospheres in accordance with EC directive 2014/34/
EU. All relevant instructions about installation, operation
and maintenance of the pump are available in the
separate pump’s instruction manual.
For protection against the risks in potentially
explosive atmospheres it is imperative that the pump
must be protected from all unauthorized operation
and unnecessary wear. Explosive gas mixtures or
concentrations of dust, in conjunction with hot and
moving parts on pump and on the driving unit, can
lead to severe or fatal personal injuries. Installation,
connection, start-up and maintenance must only be
performed by qualified technicians taking into account
the instructions reported in this manual together with all
other instructions for the installed equipment and system.
Specific regulations and requirements for the complete
system must be considered (current valid national and
regional regulations).
Since the maximum surface temperature depends mainly
on the operating conditions given by the heated fluid
in the pump, a single temperature class or maximum
surface temperature cannot be determined by the
manufacturer.
The temperature class with the maximum allowed fluid
temperature (fluids up to 120°C) is T3 (< 200°C), the
temperature class can be lowered to T4 (< 135°C) but
in this case the fluid temperature must not exceed 70°C.
Ambient temperature range: -20/+40°C.
In order to use the pump in ATEX Zone
1, it is needed to implement an ignition
protection system “b” monitoring the
temperature class required T3 (< 200°C) or
T4 (< 135°C) depending on the maximum
fluid temperature selected (120°C or 70°C,
respectively).
Specified temperature limits might be exceeded in case
the pump is operated outside the specified operating
range (temperature and pressure) and in unauthorized
modes. In addition to the temperature monitoring
device, a pressure monitoring device is mandatory if the
limits cannot be observed under all possible operating
conditions. A minimum sufficient flow through the pump
must be assured in order to remove the heat generated
by the pump operation.
Verify that heated air from other units close to the pump
does not affect the ambient temperature around the
pump (maximum ambient temperature is 40°C).
Pump must not run in dry conditions, internals must be
filled completely with, and lubricated by the liquid that
will be used during operation (including start-up, priming
and shut-off). Equip the fluid tank with a sensor level and
be sure that hydraulic connections are made at state of
the art.
Pump must always run with fluids in liquid phase.
The intended use of the equipment is:
- in an atmospheric pressure environment;
- in a fixed installation (it is not considered as handheld
equipment or equipment carried on the person).
Do not use abrasive fluids with the pump.
Only equipment with certification of conformity for the
intended ATEX zone must be used.
