TECHNICAL DATA• Asincronous 2 poles motor • Insulation class F• Protection IP55 • 1~230V ± 10% 50Hz up to 2,2 kW, 3~230/400V ±10%

50Hz up to 4 kW included, 3~400/690V ±10% above 5,5kW

Vertical multistage centrifugal pumps completely made of stainless steel AISI 304. Reliable, quiet andeasy to maintain. Suitable for municipal, Industrial and agricultural applications e.g. Fire fighting,water boosting (WRAS approved) water treatment plants, irrigation, hot and cold water movement forheating systems, cooling and airconditioners, especially suitable for boiler feed due to the robust con-struction of the pumps. IEC standard motors are used on all models.
