Description
A residential or light commercial, maintenance free, axial flanged,
in-line, cast iron, wet rotor, circulation pump for hydronic heating
systems. The NRF-22 features system liquid lubricated bearings,
non-overloading permanent split capacitor motor with impedance
protection and quiet operation. This pump may be used for water
circulating applications in hydronic and solar systems.
