Bell & Gossett Debuts New High Performance Red andBronze Fox Circulators

ITT Bell & Gossett has introduced new Red Fox and Bronze Fox Wet Rotor circulatorswith 20 to 80 percent more starting torque than competing pumps.

The Red Fox NRF-22 booster is ideal for hydronic heating applications. TheBronze Fox models NBF-12 & NBF-22 with flanged bodies and the NBF-12U & NBF-22Uwith union bodies, are superior for hot water recirculation and other potablewater applications.

The Red and Bronze Fox units feature a new Duraglide bearing system whichensures dependable start-ups year after year. The Duraglide bearing systemconsists of lime and calcium lock-up resistant ceramic shafts, and doublesintered carbon bearings. The Duraglide bearing system has wide clearancesbetween the shaft and bearings which tolerate limited dirt and fine sedimentsparticulate.

In addition to high starting torque, the new Red and Bronze Fox pumps delivermore capacity than competing brands.

The new cast-iron Red Fox is designed for residential and light commercialclosed hydronic heating system applications. The Bronze Fox incorporatesthe same performance features in a 100% lead-free bronze pump body for domesticwater systems. The Red and Bronze Fox feature a stainless steel rotor whichisolates the stator from system fluid without any chance of leakage. Inaddition, the rotor can has an integral bearing holder which helps to maintainprecision shaft and bearing alignment. Stainless steel faceplates and rotorsleeves resist corrosion.

A particle shield prevents contaminants from entering the shaft and bearingsduring the initial system fill. Both the Red and Bronze Fox are lightweightand compact for easy installation in tight areas. Wire nut leads make forfast, sure electrical hook-ups. Each unit incorporates hydraulically matchedimpellers and volutes for optimum efficiency and quiet operation.

Several accessories are available to help optimize performance and energysavings: the only U.L. approved automatic timer kit to turn the circulatorson and off at preset times, and the only U.L. approved aquastat that turnsthe circulator on or off based on system temperature. (Note: If either thetimer kit or the aquastat are used, the pump retains its U.L. listing.)The Red Fox has a flanged body in 3/4", 1", 1-1/4" or 1-1/2"pipe sizes. Bronze Fox models are available in flanged or union body. Union-bodyBronze Fox pumps have half-union connections available for 1/2" and3/4" sweat, or 3/4" female NPT, tail pieces. Bronze Fox also isavailable in 50 cycle configurations.
