property.
An incorrect use of the product leads to the loss of
the warranty.
Examples of incorrect use:
Liquids not compatible with the pump
construction materials
Potable liquids other than water (for
example, wine or milk)
Examples of incorrect installation:
Location where the air temperature is
high or there is poor ventilation.
Outdoor installations where there is no
protection
temperatures.
Environments with potentially explosive
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 use this pump to handle liquids
containing abrasive, solid, or fibrous
substances.
Do not use the pump for flow rates
beyond the specified flow rates on the
data plate.
If you have purchased a pump without a motor,
make sure that the motor is suitable for coupling to
the pump.
The motor shall be a B35 or B5 mounting
arrangement type.
In case of variable speed drive (VSD)
application,
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
demineralized etc.).
Any situation that is different from the
ones that is described and relate to the
nature of the liquid.
