McDonnell & Miller 340400 Seal Assembly
The McDonnell & Miller 340400 Seal Assembly, also categorized under model number SA27T-75, is a critical replacement component engineered for use with Series 25-A make-up water feeders. Designed to maintain the integrity of the diaphragm seal within the feeder system, this assembly ensures consistent boiler water level control by preventing bypass leakage between the float and valve chambers. This replacement diaphragm assembly is built to withstand maximum water supply pressures of 100 psi and operates effectively in systems with a maximum vessel pressure of 35 psi. As a genuine Xylem-McDonnell & Miller part, the SA27T-75 provides the exact tolerances required for proportional feed action in boiler receiver tanks. Technicians should note that this assembly includes the necessary F-26 gaskets for a complete field service repair. Maintaining a functional float operated water feeder is essential for preventing low-water conditions and ensuring the reliable operation of commercial and industrial hydronic systems.
Key Benefits- Ensures a precise diaphragm seal to maintain system pressure and prevent valve chamber leaks.
- Compatible with all McDonnell & Miller Series 25-A make-up water feeders and 25A-HD head mechanisms.
- Includes F-26 item 1 gaskets for a comprehensive and efficient installation during routine maintenance.
- Constructed for industrial durability with a maximum inlet water temperature rating of 120°F.
- Supports proportional feed performance to maintain optimal water levels in boiler receiver tanks.
Which water feeders are compatible with the SA27T-75 seal assembly?
This 340400 assembly is specifically designed for the Series 25-A make-up water feeder. It is the direct OEM replacement for the internal diaphragm seal in these units.
Does the assembly include the required gaskets for installation?
Yes, the SA27T-75 comes with the F-26 gasket (item 1 in the technical manual), allowing for a complete seal replacement without ordering additional separate components.
What are the pressure limits for this diaphragm assembly?
The assembly is rated for a maximum supply pressure of 100 psi and a maximum vessel pressure of 35 psi, making it suitable for most standard low-pressure steam and hot water applications.
