The closed-loop Bell & Gossett NRF-22 Inline Circulator Pump is designed for use in domestic and light commercial water circulating systems, such as hydronic heating and low-pressure boosting. The high starting torque and the DuraGlide permanently-lubricated ball bearings on this pump make for years of dependable start-ups. The closed impeller design improves operating efficiency and the self-cleaning particle shield protects the shaft and bearings from system start-up debris. The face plate and rotor sleeve feature corrosion-resistant stainless steel construction.
The Bell & Gossett 103251 is not for use in potable water systems. This pump may also be referred to by the Bell & Gossett model number NRF-22.

Water StoveWednesday, May 09, 2012
I use this pump on my water stove that I made about 25 years ago.
Last longer. This is the fourth one on the circulating hot water. The pump part spins on the shaft

Bell & Gossett is the industry's best pump.
Great Recirc PumpTuesday, December 06, 2011
I have used this recirc pump for my hot water in my house for 12 years without a problem. It was finally starting to make some noise and I thought I should go ahead and replace it. I looked around the internet a little and DrillSpot beat them all on price and service. I will definately go to them again.

Worked great. Was the exact model of the one I replaced. Back in business in no time.
Easy installation. The price was great, better than anywhere else I checked. The shipping was very fast.
Nothing. It fit the bill.

Great residential replacement for the commercial B&G 100. Flanges lined right up. Shipping was as promised with no suprises.
Price was a quarter of the B&G 100
Nice just the way it is
Ahhh Warm Water Again!Friday, January 14, 2011
This product is awesome. But....you must remember to unplug it before shutting off the main water line. The previous pump burned out because the plumber shut off the water to do some repairs.
If it automatically shut off when water flow stopped.
