motor or, in case of a not balanced
distribution of weights, to partially lift the unit
vertically
starting
displacement.
Pump unit must always be fixed and transported as
shown in Figure 6 on page 90, and the pump without
motor must be fixed and transported as shown in
Figure 7 on page 90.
In this last case remove coupling guards from drive
lantern and cross the lifting ropes/bands.

Product Description
3.1 Pump design
Centrifugal pump coupled to an ATEX electric motor.
The pump can be used for handling:
•
Hot or cold liquids
permissible temperature of 90°C (162°F)
and a variable minimum temperature (see
data plate).
•
Liquids which are moderately aggressive to
the pump materials.

Intended use
The pump is suitable for:
•
Use
in
environments
explosive atmospheres, due to presents of
flammable substances in the form of gas,
vapor, or mist.
Improper use
WARNING:
Improper use can create dangerous
conditions and cause personal injuries
and damage to property.
Improper product use can make the warranty void.
Examples of improper use:
•
Liquids not compatible with the pump
construction materials
•
Potable
liquids
example, wine or milk)
Examples of improper installation:
•
Room with high air temperature and/or poor
ventilation.
•
Outdoor installations where there is no
protection
against
temperatures
•
Environments
atmospheres, due to the presence of
flammable substances in the form of dust.
•
Underground parts of mines and in parts of
surface installations of such mines where
only equipment of Group I can be expected
to use.
NOTICE:
•
Do not pump liquids containing abrasive,
solid, or fibrous substances.
•
Do not use the pump for flow rates
beyond the specified flow rates on the
data plate.
•
Make sure that the liquid inside the pump
does not freeze or crystallise.
•
The pumped liquid must be chemically
and mechanically non aggressive.
•
The auto-ignition temperature of the
pumped liquid must be ≥ 50°C (122°F) at
the maximum surface temperature T4.
•
In case of variable speed drive (VSD)
application,
contact
Authorised Distributor.
Special applications
Contact Xylem or the Authorised Distributor in the
following cases:
•
If the density and/or viscosity value of the
pumped liquid exceeds the value of water,
such as water with glycol; as it may require a
more powerful motor.
•
If the pumped liquid is chemically treated (for
example softened, deionized, demineralized
etc.).
•
Any situation that is different from the ones
that is described and relate to the nature of
the liquid.
