NRF-36 Circ Pump

Series NRF cast iron pumps are small, reliable, in-line circulator pumps intended to pump water through closed loop systems for heating and cooling in residential and light commercial settings. The Series NRF features a maintenance-free system, with a self-cleaning particle shield protects the shaft and bearings from system start-up debris. The unique DuraGlide bearing system also contributes to trouble-free start-ups. A powerful, three-speed Red Fox motor offers high starting torque, ensuring consistent start-up season after season. The Series NRF’s stabilized heat-resistant, non-metallic impeller with a closed design improves overall operating efficiency. Mounting hardware and flange gaskets are included with the pump. Flanges are available separately in 3/4″, 1″, 1-1/4″, and 1-1/2″.
