Dual-stator system cuts environmental impact

Netzsch Pumps product story

The iFD-Stator prolongs stator lifetime and reduces lifecycle costs thanks to its manoeuvrability within the two-part re-usable housing.
Netzsch's iFD-Stator dual-stator system is now fitted as standard to all NM series pumps with a nominal rotor diameter between 21 and 63mm.
The dual-stator system comprises of a stator and stator housing that the company claims differs from all existing stators by offering significant advantages in capacity, economy and environmental protection, with the system being endorsed by the Deutsche Bundesstiftung Umwelt (German Environmental Foundation).
The iFD-Stator, which is compatible with all Nemo pumps from the NM series, prolongs stator lifetime and reduces lifecycle costs thanks to its manoeuvrability within the two-part re-usable housing.
The use of a separate housing and stator means that, when worn, only the stator needs to be replaced and is therefore more easily disposed of.
During assembly, the over-sized stator easily slides over the rotor, allowing the optimum operating dimension to be achieved through axial constriction.
Its reduced initial breakaway torque allows for the selection of smaller pump drives, which means that investment costs and energy consumption are reduced.
With the addition of an optional regulator, the iFD-Stator can be infinitely adjusted to process parameters such as temperature, working pressure and continuous wear compensation, which can also result in extended stator and rotor life.
The iFD-Stator is manufactured to tight production tolerances, is available with S and L geometries and capable of transferring media at rates from 0.5 to 50m3/h at pressures of up to 12bar.
