Bell & Gossett has introduced new 3-speed NRF wet rotor circulators for residential and light commercial heating systems.

The new Bell & Gossett circulators - models NRF-36 and NRF-45 - are equipped with 3-speed motors, which allow the pumps to cover a wide range of hydraulic capabilities.

Benefits of the 3-speed NRF circulator line include:

• Three-speed switch provides more performance flexibility


• Multiple hydraulic settings allow one NRF pump to replace several competitors' pumps, resulting in lower inventory levels


• High starting torque


• Unique Bell & Gossett DuraGlide(tm) Bearing System


• Heat resistant and non-metallic closed impeller design
