Wilo-NR
Submersible multiple stage well pump for water
supply, irrigation and watering, pressure
boosting, dewatering and industrial
applications.
Description / Design
Hydraulics: NEMA coupling and interconnector accepts any
North American motorNon-return valve installed in pump
head Over sized intermediate bearings in each stage,
specially constructed to improve the shaft deflection
Easily replaceable wear rings and bearings Robust cable
protection Hydraulic components improved to achieve high
levels of efficiency High resistance to corrosion and
abrasion achieved through the properties of the
stainless steel Easy to service through simple
installation and removal of the unit.
