Hoffman Watchman WC-6-20B Condensate Pump (160029)

Hoffman 160029 WC-6-20B Watchman

The Hoffman 160029 WC-6-20B is a compact “Watchman” series condensate pump designed for smaller steam heating loads. It utilizes a 6-gallon cast iron receiver, providing a mechanically robust yet space-saving solution for residential or light commercial applications. The centrifugal pump is engineered for 1750 RPM, delivering 9 GPM at 20 PSI. Its low-inlet design facilitates easy connection to existing return lines, while the cast iron body offers an exceptional lifespan in the harsh thermal environment of a steam boiler room.

Driven by a 1/3 HP motor, the WC-6-20B is optimized for single-phase electrical stability. The unit includes a factory-wired float switch that controls the electrical engagement of the pump, preventing dry-run conditions and ensuring efficient operation. By maintaining a constant torque-to-load ratio, the drive assembly preserves the life of the high-temperature mechanical seal, ensuring a leak-proof interface between the pump and the motor shaft for years of service.
