The type NMR is a volute casing pump with housing dimensions according to ISO 2858 and magnetic coupling.
The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside.
An internal circulation current dissipates the heat generated by the eddy current losses.
The bearing of the pump shaft takes place in SiC plain bearings, the drive shaft is mounted in oil-lubricated roller bearings. Wear rings are standard on the suction and pressure sides.
The axial thrust compensation is done by relief holes, back buckets or other measures.
In addition to the standard version, the following special constructions are available:
- Pump housing with heating jacket
- Spiral housing with center-mounted suspension
- Version with open impeller and wear disc
- inducer
- oil & gas
- chemistry
- petrochemistry
- offshore
- ship technology / marine
- refueling equipment & aviation
- tank storages / tank farms
- renewable energy / environmental engineering
