Type NML is a standard chemical pump PN16 according to ISO 2858 with magnetic coupling.
Adapted from the characteristic diagram sizes and the requirements of the operator, it is graded so that the best possible efficiency is achieved.
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 is carried out in SiC plain bearings, the drive shaft is mounted in permanently grease-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
- Version with open impeller and wear disc
- inducer
