Permitted Use
The pump is suitable for:
• Civil and industrial water distribution systems
• Irrigation
• Water treatment
• Washing systems
• HVAC (heating and cooling)
Prohibited Use
The pump is not suitable for:
• Pumping liquids not compatible with the product construction materials
• Pumping hazardous liquids (for example toxic, explosive, inflammable or corrosive liquids)
• Pumping food grade liquids other than water (for example wine or milk)
• Pumping liquids containing abrasive, solid or fibrous substances
• Working outside of the rated capacity field specified on the data plate
Examples of unsuitable installation:
• Environments with explosive or corrosive atmospheres
• Outdoor installations without protection from atmospheric agents (e.g. sun, rain, high or freezing temperatures)
WARNING: Do not use this pump for inflammable or explosive liquids.
Misuse may create hazardous conditions and cause personal injury and material damage. Misuse of the
product may nullify the warranty.
Special Use
Contact the sales and support service in the cases below:
• If the pump is used to pump liquids with viscosity or density greater than water (a motor with a proportionately
higher power should be used),
• The water to be pumped has been chemically treated (softened, chlorinated, demineralized, etc.),
• In any other situation other than those listed under permitted use.

4.2 Technical Data

4.2.1 Liquid Temperature

Pumped liquids must remain within certain temperature limits:
• with EPDM seals (standard versions): from -22 °F to 248 °F (-30 °C to 120 °C)
• with VITON©/FKM seals (special versions): from 14 °F to 248 °F (-10 °C to 120 °C)

4.2.2 Ambient Temperature and Altitude

In the case of ambient temperatures higher than 104 °F (40 °C) , or the installation of the pump at an altitude higher
than 1,000 meters, the motor must not work at full capacity to avoid the risk of overheating. Excessive ambient
temperatures and low air density reduce the motor's ability to cool down. In these cases, it may be necessary to
use a motor with a higher rated power. Figure 5-A is a non-binding chart of motor capacity percentage based on
altitude and temperature.

4.2.3 Maximum Number of Motor Starts

The table shows the maximum number of start-ups per hour for the pumps supplied with a standard motor.
Power HP (kW)
1/2 - 3/4 (0.37 - 0.55)
1 - 4 (0.75 - 3)
5 - 10 (4 - 7.5)
15 - 30 (11 - 22)
40 - 75 (30 - 55)
100 - 250 (75 - 200)
With a motor other than the one supplied as a standard, check the motor manual for the maximum number of starts
per hour.
