watermotor-drivenself-priming

THESE ELECTRIC MOTOR-DRIVEN, SINGLE IMPELLER PUMPS, WITH AXIAL INTAKE AND RADIAL DELIVERY ARE PARTICULARLY SUITED FOR USE IN INDUSTRIAL, CIVIL AND AGRICULTURAL APPLICATIONS, AS WELL AS IN HEATING AND WATER SUPPLY SYSTEMS. SCOPE OF APPLICATION: These electric motor-driven, single impeller pumps, with axial intake and radial delivery are particularly suited for use in industrial, civil and agricultural applications, as well as in heating and water supply systems. It is recommended that these pumps are used to carry only chemically pure liquids and free of foreign matter, with temperatures not higher than 80°C. PUMP: Horizontal axis pump with bronze impeller, pump body and base support made of G20 cast iron, AISI 416 stainless steel shaft and mechanical seal made of ceramic/ graphite. Impeller can also be made of Noryl with 20% glass fibre for models up to 1 HP. MOTOR: Electric, closed-type with external cooling fan, IP 44 safety class. F insulation. The standard versions of single-phase motors are fitted with termostat-controlled safety microswitches to avoid undesirable damages to the motor. The user must provide protection for three-phase electropumps. TENSION: STM: 230-240 V. 50 Hz; ST: 230/400 V. 50 Hz. Different voltage and frequency ratings are available on request. APPLICATIONS: Domestic, Agriculture, Industry
