RANGE OF PERFORMANCE Flow rate up to 400 l/min (24 m³/h) Head up to 112 m LIMITS OF USE Manometric suction lift up to 7 m Liquid temperature up to + 90°C Liquid temperature up to + 40°C in the 2CPX version (with technopolymer impeller) Environment temperature up to+ 40°C INSTALLATION AND USE They are recommended for pumping clean water and liquids that are chemically non aggressive to the materials from which the pump is made. THEIR HIGH EFFICIENCY AND ADAPTABILITY TO THE MOST VARIED, EVEN UNUSUAL APPLICATIONS, MAKE THEM THE IDEAL CHOICE IN THE DOMESTIC, CIVIL AND INDUSTRIAL FIELD; IN PARTICULAR FOR DISTRIBUTING WATER IN COMBINATION WITH PRESSURE SETS, FOR INCREASING PRESSURE IN THE MAINS, FOR FIREFIGHTING SETS. The pumps must be installed in enclosed places, or at least protected against inclement weather. CONSTRUCTION CHARACTERISTICS MOTOR SHAFT: stainless steel EN 10088-3 - 1.4104. MECHANICAL SEAL: ceramic - graphite - NBR. ELECTRIC MOTOR: the pumps are close-coupled to a carefully matched PEDROLLO electric motor, with high efficiency (class EFF1 for powers from 4 to 7.5 kW), quiet running, totally enclosed fan cooled (TEFC), suitable for continuous duty. 2CPm: single-phase 230 V - 50 Hz with capacitor and thermal overload protector (up to 1.5 kW). 2CP: three-phase 230/400 V - 50 Hz up to 4 kW. 400/690 V - 50 Hz from 5.5 to 7.5 kW. INSULATION: class F. PROTECTION: IP 44. 2CP 25/130N PUMP BODY: cast iron, with threaded ports ISO 228/1. BODY BACK-PLATE: stainless steel AISI 304. IMPELLER: stainless steel AISI 304 of the type with centrifugal radial flow. Other 2CP PUMP BODY: cast iron, with threaded ports ISO 228/1. IMPELLERS: brass, of the type with centrifugal radial flow. |
