PUMP INSTALLATION AND APPLICATIONS

• These pumps are recommended for clean water and fluids that are not chemically aggressive to the pump components.
• THEY ARE PRINCIPALLY USED FOR CIVIL, INDUSTRIAL AND AGRICULTURAL APPLICATIONS, WHICH BENEFIT FROM THEIR STURDINESS AND RELIABILITY. 
• They are manufactured to EN 733 - DIN 24255 standards. Overall dimensions, sizes and positions of suction and delivery ports, support feet and other dimensional characteristics comply with these standards. 
• Users can be sure these pumps will meet even the most demanding heavy-duty needs and that they can be easily interchanged with other standardized pumps. 
• The design allows dismantling without disconnecting the pump body from the pipeline (back pull-out), making them easy to use in a variety of conditions.

PERFORMANCE

• F pumps come in a wide and diverse range. The wide range makes it easy to select the correct model for each application.
• Together with high performance efficiency, this means big savings in operating costs since these are powerful machines often intended for continuous duty.
• Long stable characteristic curves.
• Performance characterized by high absolute values over the majority of the curve;
• Flat absorption curves at high delivery rates, to prevent motor overloading even during prolonged use. 
• Good suction capacities at both low and high delivery rates. 
• Curve tolerance according to ISO 2548.

APPLICATION LIMITS

• Manometric suction lift up to 7 m
• Liquid temperature between -10 °C and +90 °C
• Ambient temperature between -10 °C and +40 °C
• Max. pressure in pump body 10bar (PN10)
• Continuous service S1

STRUCTURAL CHARACTERISTICS

• Cast iron PUMP BODY manufactured to EN 733 - DIN 24255 AND UNI 7467-NF E-44-111 Standards, built with flanged suction and delivery ports 9UNI 2236 PN10).
• Cast iron back-plate / motor bracket incorporating the mechanical seal housing. 
• BRASS IMPELLER centrifugal radial flow type. (CAST IRON on 50/250 and above) 
• AISI 316 stainless steel MOTOR SHAFT 
• Ceramic and graphite MECHANICAL SEAL 
• MOTOR: pumps are coupled directly to an asynchronous, high efficiency PEDROLLO induction motor of suitable size, which is quiet running, closed and externally ventilated, suitable for continuous duty. INSULATION class F

All three phase motors require an adequate external motor protector connected according to current standards.

• PROTECTION IP 55
• CONSTRUCTION AND SAFETY STANDARDS in compliance with EN 60 335 -1, (IEC 335-1, CEI 61-150) EN 60034-1 (IEC 34-1, CEI 2-3).
