Water pump NMM Series

electriccentrifugalindustrial

NM m-Drive series pumps are single stage, end suction, seal-less volute type pumps with magnetic coupling. • Single entry, closed impeller is hydraulically thrust compensated and dynamically balanced. • Main dimensions according to EN 733. • Pump and motor are connected to each other on a base plate by using magnetic coupling. • Pump can be dismantled without removing pump casing thus maintenance and assembly operations can be easily performed. • Silicium carbide plain bearings which are lubricated by process fluid are used in NM m-Drive series pump. • Thanks to magnetic couplings which are used in NM m-Drive series pumps, zero leakage is provided. Outer magnetic rotor is rotated by motor shaft and inner magnetic rotor is rotated synchronously to outer magnetic rotor by magnetic forces without any physical contact. Inside of the pump is isolated from environment by containment shroud and zero leakage is guaranteed.
