Water pump NM series

electriccentrifugalfor marine applications

• Single-stage, end-suction centrifugal volute pumps. • Main dimensions, compatible with EN 733 (DIN 24255) norm. A total of 45 designed pumps avaible in the series. • Single suction with closed impeller and thrust balanced by means of counter-balancing holes and back wear rings, thus acquiring a dynamic balance. • The Pump and the motor have a standart connection to the common base plate with a flexible coupling. Maintenance and repair procedures are easily carried out since the pump fixtures can be removed with the volute body. • Use of extended coupling also enables the removal of the pump fixtureswithout moving the motor or the volute body. • The series has been designed so that parts are easily replaced and standardized. The entire series is made of only 5 bearings and 5 shaft types, thus simplifying spare parts procurement. FIELDS OF APPLICATIONS • Water supply and booster stations. • Irrigation, sprinkling, drainage processes. • Tank systems. • Hot-cold water circulation in cooling systems. • Pumping of condensed water. • Circulating water in pools. • Industrial and domestic fluid pumping processes. • Marine applications
