Model NMT

Model: NMT
Standard: DIN EN ISO 2858, ISO 15783

Model NMT is a volute casing submersible pump with shaft seal according to the principle of the two-pipe pump, i. e. separate shaft sealing pipe and pressure pipe. The hydraulic pump part is arranged in the container or in the pumped medium.

The connection is made by a multi-level shaft and pipe string. With the NMT, submersible length of up to 6 meters are possible with a flow rate of up to 1000 m³/h [4400 gpm].

The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside. The direct mounting of the drive motor eliminates additional bearings and the mechanical coupling.
