Bell & Gossett AutoCirc series circulators are engineered with a high efficiency ECM (Electronically Commutated Motor) technology, specifically designed for standard water heaters. These circulators are lead free and come assembled with a timer, cord, and plug. Models in this series feature a fixed thermostat that automatically turns the pump ON when water temperature in the hot water line reaches a certain degree and turns it OFF when water temperature reaches a lower degree, ensuring hot water availability only seconds behind. When the pump is OFF, a built-in auto closure device prevents any other hot-to-cold line or cold-to-hot line mix. Features Silent during operation Requires only one pump and one installation for all fixtures on the hot water plumbing line Does not require a return line Saves money and thousands of gallons of water annually Built in 24-hour timer which allows the selection of system operating periods to suit family usage Built-in fixed thermostat Comes complete with a 6 ft. long power cord Designed for potable water applications BELL & GOSSETT AUTOCIRC SERIES RE-CIRCULATION PUMPS Model Comparison Chart Model Connection Size Height Width Voltage Max Pressure (PSI) Max Working Temp (F) e3-4_/BDPQC 1-/2" 8" 4-1/2" 115 145 203 e3-4_/BDPRC 1/2" 8" 4-1/2" 115 145 203 DIMENSIONS DIAGRAM FEATURES BROCHURE Bell & Gossett AutoCirc Series Re-Circulation Pump Brochure INSTRUCTIONS Bell & Gossett AutoCirc Series Re-Circulation Pump Instructions Pump Products application engineers are standing by to help you find the right pump, as well as to provide price quotes, stocking availability and shipping information.

The Bell & Gossett Ecocirc series is designed with a highly efficient Electronically Commutated Permanent Magnet Motor (ECM/PM) technology specifically for hydronic systems. Ecocirc pumps are protected against dry run conditions. This series recognizes when there is no water in the pump housing and automatically stops the pump until the presence of water is detected.   Features Cast iron pump body construction Magnetically centered spherical impeller/rotor Electronically commutated shaft-less spherical motor with permanent magnet technology Rotor/impeller with anti-block technology that separates the main flow of the pumped media completely from the permanent magnetic parts, preventing the circulator block-up even in an old open system Step-less speed dial with LED for pump status and troubleshooting BELL & GOSSETT ECOCIRC SERIES CIRCULATOR PUMPS Model Comparison Chart Model Connection Size Max Pressure (PSI) Voltage Phase GPM Max.

The Grundfos Comfort System is a hot water recirculation system. This series eliminates cold water line runoff at the faucet using a bypass valve and pump with a timer to control water flow while delivering instant hot water. Special Features • The ultimate in convenience is having hot water instantly available at sinks, appliances and bathroom faucets. The elimination of time spent waiting is especially convenient in areas where the installation of low flow showerheads and faucets are required by law. • Hot water recirculation improves the efficiency and effectiveness of household appliances including washing machines and dishwashers by having hot water available instantly. • Users can save energy by setting the 24 hour programmable timer to make hot water available during peak demand times, such as early morning and in the evening. • The recirculation pump can be installed by a certified contractor in two hours. For the average home, hot water recirculation systems generally cost a few hundred dollars, including parts and installation. • A wet rotor design for whisper-quiet and maintenance-free operation. • Stainless steel rotor cladding and canister construction, an exclusive UP 15 series feature, ensures corrosion-resistance and extended product durability. • A low-watt, two-pole motor combined with low-flow performance mitigates heat loss and ensures minimum water heater operating costs, pipe and water heater wear and energy consumption. • Significant water (and sewer) disposal savings, retaining the 12,000 to 38,000 gallons of wasted water a typical U.S. home wastes annually waiting for their hot water heater. Some fast-growing counties are making the installation of hot water recirculation pumps mandatory for all new construction projects to prevent heat loss.
