Centrifugal Pumps

CENTRIFUGAL PUMP Flow rate up to 6000 L/min (360 m³/hr) Dynamic head up to 95 m See pump performance info below for specific pump details. 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. 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 A thermal cutout relay (motor protector) is incorporated in single phase motors up to 1.5 kW. The remaining single phase motors and 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).
