Bell & Gossett Condensate Return Pump Series CB
Condensate return units for systems up to 90,000 sq. Ft. EDR. The CB is designed for systems with low return lines. This condensate unit features the B-35 pumps which has a suction inducer to create a positive pressure at the centrifugal impeller thus guaranteeing low NPSH pump requirements.
The CB units require only 2′ NPSH and can pump condensate up to 210°F (99°C) at sea level. Series CB units include cast iron receivers, sized from 23– 250 gallon (87 – 946 liters). The cast iron receiver includes a 20 year warranty against corrosion. CB units are available in either simplex or duplex design. Receivers have a low height NPT inlet for easy return line piping and a separate NPT overflow that can be used as a secondary vent.
All simplex units include a two pole float switch. Duplex units include float switches (a mechanical alternator is available). All pumps are bronze fitted with bronze case wear rings and stainless steel shafts.
