Maintain consistent boiler water levels automatically with the reliable McDonnell & Miller 47-2-M mechanical water feeder, identified by part number 132900. This unit provides essential level control for low-pressure steam boilers, helping to prevent dry-firing and potential system damage by ensuring proper water replenishment based on internal float position.
The unit functions through a high-precision float-operated valve mechanism that triggers water flow whenever the boiler water level drops below the pre-set threshold. Integrated with the #2 switch, it provides a dual-function capability, offering both mechanical makeup water feed and low-water cut-off control to safeguard your hydronic assets from overheating.
Key System Performance Baselines:
- Precision Control: Automatically restores water levels to maintain safe operation.
- Dual Functionality: Integrated #2 switch for reliable low-water cutoff signaling.
- Robust Construction: Engineered for durability in demanding steam boiler environments.
- Maintenance Friendly: Simplifies routine boiler management and system longevity.
⚠️ Application Profile: Designed specifically for low-pressure steam boilers in commercial and residential heating systems requiring automated makeup water regulation.
