NR - Series
FEATURES
- Counter rotating, twin rotary lobes provides for optimal volumetric
efficience.
- Submersible design minimizes installation expenses by reducing noise
levels and dramatically reduces wear, (up to five times), to all rotating
parts due to lower operating temperatures.
- Highly efficient, continuous duty, air filled, copper wound motor with
class E, B insulation operates at lower temperatures and minimizes the cost of
operation.
- Built in thermal & amperage sensing, protector prevents motor failure due
to overloading, single phasing (in three phase units), or accidental run-dry
conditions, (1/2 ~ 10 Hp.). Miniature Motor protectors are supplied in all
three legs.
- Double shielded, permanently lubricated, high temperature C3 ball bearings
are utilized for the top bearings and oil lubricated ball bearings on the
bottom, rated for a B-10 life of 60,000 hours.
APPLICATIONS
- Aeration and preliminary aeration at combined liquid waste treatment
facilities
- Aeration for aquiculture and fish ponds.
- Aeration for sewage treatment plants.
