Bell & Gossett’s complete line of in-line and base-mounted centrifugal pumps and circulators can handle virtually any HVAC requirement. The pumps are engineered for exceptional performance and rugged durability. They are designed for easy maintenance and to be highly energy efficient. The pumps provide reliable operation in a variety of applications, including hydronic heating and cooling systems, industrial, refrigeration, cooling towers and irrigation. All B&G pumps are manufactured at an ISO 9001- approved facility.
Airtrol Tank Fittings
Helps establish proper initial liquid level in the compression tank when filling the hydronic system. They also help maintain proper system pressurization by directing released air to the compression tank during system operation and
permit cooler liquid flow to the boiler during the off cycle as system liquid cools. Airtrol Tank Fittings must be used with the appropriate sized Airtrol Boiler Fitting, In-Line Airtrol or Rolairtrol air separator.
ASME Expansion Tanks – Series WTA Pre-Charged Tanks
Designed for Potable Well Water and Booster Pump Systems. The Series WTA expansion tank is an ASME constructed pre-charged vessel. The WTA tanks will help protect the pump and pressure switches against short cycling. The well tank delivers adequate water under pressure between pump cycles to meet the required demand. It will provide economical system operation by minimizing pump starts, extending the life of the pump motor, and saving energy. The WTA tank will also assist the pump in meeting peak demand.
ASME Safety Relief Valves
Protect fired and unfired hot water vessels against hazardous operating pressures. Features and Benefits Engineered in accordance with Section IV of the ASME boiler and pressure code for heating boilers with capacities certified by the National Board of Boiler and Pressure Vessel Inspectors.Offer the highest BTUH ratings available on the market today for valves in their class (790,000 to 5,999,000 BTUH) EPDM diaphragm operated (cast iron models) and diaphragm assisted (bronze models) have an effective area approximately 5 times greater than conventional “pop-type” ”relief valves to help overcome the effects of fouling.Low differential between opening and closing pressures helps to prevent conditions under which system water might flash to steam and cause hammering.
Circulator Pump – Series LD3, HD3, and PD Flexibly Coupled In-Line Heating and Potable Water Recirculation Pumps
For applications requiring higher flow and head pressures, Bell & Gossett provides an entire range of booster pumps. The designs of these pumps are based on three-part configuration which offers complete field repairability and compact construction. All Bell & Gossett boosters are equipped with the incomparable B&G manufactured motor for quiet and efficient operation.
