Improper use
WARNING:
Improper use of the pump may create
dangerous conditions and cause person-
al injury and damage to property.
An improper use of the product leads to the loss of
the warranty.
Examples of improper use:
• Liquids not compatible with the pump construc-
tion materials
• Hazardous liquids (such as toxic, explosive, flam-
mable, or corrosive liquids)
• Potable liquids other than water (for example,
wine or milk)
Examples of improper installation:
• Hazardous locations (such as explosive, or cor-
rosive atmospheres).
• Location where the air temperature is very high
or there is poor ventilation.
• Outdoor installations where there is no protection
against rain or freezing temperatures.
DANGER:
Do not use this pump to handle flamma-
ble and/or explosive liquids.
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.
Special applications
Contact the local sales and service representative in
the following cases:
• If the density and/or viscosity value of the pump-
ed liquid exceeds the value of water, such as wa-
ter with glycol; as it may require a more powerful
motor.
• If the pumped liquid is chemically treated (for ex-
ample softened, deionized, demineralized etc.).
• Any situation that is different from the ones that is
described and relate to the nature of the liquid.
