12 lose oupled entrifugal Pumps Features NM utting edge hydraulics The geometry of the impeller and the pump casing are optimized to achieve maximum efficiency and the best suction capability. Flexible The option to choose between cast iron and bronze materias for the hydraulic parts in contact with the pumped liquid allows NM and NM series pumps to be selected for use with different types of liquids. ompact esign The compact design allows for easy installtion even in confined spaces. xclusive design n innovative, patented guard prevents contact with rotating parts, proving protection to the end user whilst allowing for inspection of the mechanical seal. Reliable The bearing and shaft are designed to ensure the reduction of the stress, providing high reliability under all operating conditions. NMS utting edge hydraulics The geometry of the impeller and the pump casing are optimized to achieve maximum efficiency and the best suction capability. Flexible The option to choose between cast iron and bronze materias for the hydraulic parts in contact with the pumped liquid allows NMS and NMS series pumps to be selected for use with different types of liquids. New lantern bracket construction The lantern brackets incorporate a thrust bearing on the hydraulic side which guarantees the elimination of additional loads on the motor bearings. The flange is sized to be used with standard motors. xclusive design n innovative, patented guard prevents contact with rotating parts, proving protection to the end user whilst allowing for inspection of the mechanical seal. Simplified motor maintenance The presence of the thrust bearing on the hydraulic side makes it easier to remove the motor, facilitating maintenance operations and eliminating the risks of damage to the hydraulic parts.
