The improved terminal box for the SuperBruteâ„¢ three-speed circulator has flexibility, torque, and full-flow features designed for hydronic heating and radiant panel installations, the company says. The new drip-proof design makes speed selection simple with a thumb-operated high-medium-low rotary switch, states the manufacturer. The pump includes a removable check valve, contributing a large flow range of 0 to 17 gallons per minute and a head range of 0 to 19 feet. The maximum fluid temperature for a closed system is 230 degrees F with a minimum fluid temperature of 36 degrees. The SuperBrute has a 115-volt, 1/25-hp, two-pole, single-phase motor.
