Nm mDrive Series

DESIGN

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.
