McDonnell & Miller 221 Water Feeder
The McDonnell & Miller 221 Water Feeder (Part Number 126600) is a heavy-duty mechanical make-up water feeder specifically engineered for boiler receiver tanks in commercial and industrial hydronic systems. This float-operated unit provides precise proportional feed action, maintaining critical water levels without the need for complex equalizing connections. Built to handle a maximum vessel pressure of 35 PSI and a water supply pressure up to 150 PSI, the Model 221 features a 3/4" NPT connection and a robust mounting flange designed for an 8 1/2" bolt circle with six 17/32" holes. Its soft seat design ensures a positive seal, preventing seat leakage and protecting against overfill conditions. Ideal for condensate receiver tanks, this feeder simplifies installation by mounting directly to the vessel, ensuring reliable boiler feed water regulation and system stability even in high-demand environments.
Key Benefits- Direct Vessel Mounting: Eliminates the traditional requirement for equalizing lines, reducing installation labor and potential leak points.
- Proportional Feed Control: Delivers precise mechanical water level management by adjusting flow based on the float position rather than simple on/off cycling.
- High-Pressure Capability: Rated for a maximum inlet water pressure of 150 PSI and temperatures up to 120°F (49°C).
- Positive Seal Technology: Features a soft seat valve assembly that provides a tight shut-off to prevent common bypass and flooding issues.
- Serviceable Design: The 8.5-inch bolt circle flange allows for easy access to internal components, including the float and valve linkage, for routine maintenance.
Does this unit require equalizing piping for installation?
No, the Series 221 is designed for direct mounting to the side of receiver tanks, which removes the need for equalizing connections typically required on other mechanical feeders.
What is the maximum operating pressure for the receiver tank?
The McDonnell & Miller 126600 is rated for a maximum vessel pressure of 35 PSI. Exceeding this pressure can impact the float buoyancy and valve performance.
Can this feeder be used on steam boilers directly?
While used in steam systems, this specific model is designed for makeup water on condensate receivers and boiler feed sets rather than mounting directly to the steam boiler's water column.
