This mechanical water feeder provides reliable, automatic water level control for steam heating boilers, helping to prevent low-water conditions that can damage equipment. The McDonnell & Miller 133400, also known as the Model 47-X, is designed for high-performance fluid management without the inclusion of quick hook-up fittings, making it an ideal choice for direct-piped installations.
Operating on a gravity-fed buoyancy principle, the feeder utilizes a precision-engineered internal float mechanism that detects water level fluctuations. As the water level drops, the valve assembly opens to allow make-up water to enter the system until the desired set point is achieved, ensuring optimal system stability and protection.
Key System Performance Baselines:
- Automatic Regulation: Maintains consistent water levels during daily boiler cycles.
- Robust Construction: Engineered to withstand the rigors of high-temperature steam environments.
- Installation Versatility: Designed for permanent, secure piping configurations in commercial and residential steam applications.
⚠️ Application Profile: Primarily intended for low-pressure steam boilers requiring consistent, automatic make-up water replenishment. Always ensure the system is properly isolated and drained before attempting to remove or replace existing feeder components.
