motor and motor bracket). Please handle the pump
carefully so as not to damage the unit. Refer to
Fig. 3 (page 3) - Proper Lifting
for proper lifting
procedures and guidelines.
CAUTION ! Outside influences may cause damages !
If the delivered material is to be installed later on,
store it in a dry place and protect it from impacts.
4. Application

5. Technical data
5.1 Technical data
- Maximum operating pressure please Refer to Fig. 5
(page 6) - Maximum Operating Pressure and Inlet
Pressure
• Maximum suction pressure: 145 PSI (10 BAR)
- Temperature range
• Fluid temperature: 5 to 248°F (120°C)
• Ambient temperature: 32 to 104°F (40°C)
WARNING
If ambient temperatures are above 104°F, or if the pump is
located at elevations more than 3,281 feet (1,000 meters)
above sea level, the motor’s output must be decreased to
compensate for less effective cooling, and may have to be
replaced with a stronger motor.
