Product Details

The McDonnell & Miller 51S-2 is a high-capacity mechanical water feeder designed to automatically maintain proper water levels in low-pressure steam and hot water boiler systems. This reliable float-operated device features an integrated automatic cutoff mechanism that shuts down the burner when unsafe water conditions are detected, providing critical boiler protection.

Key Features:

  • High-capacity mechanical water feeding for larger boiler systems
  • Built-in automatic cutoff switch for burner shutdown protection
  • Float-operated mechanism for reliable, maintenance-free operation
  • Dual functionality: maintains water level and provides low-water cutoff safety
  • Suitable for low-pressure steam and hot water heating systems
  • Designed for commercial and industrial boiler applications

This mechanical water feeder combines the essential functions of automatic water makeup and low-water safety protection in a single robust unit. The float mechanism responds to changing water levels to add makeup water as needed, while the cutoff feature prevents dangerous dry-firing conditions by interrupting burner operation when water drops below safe levels.

Price was very reasonable. Original OEM product. Quick ship time. I was very pleased with Boatplicity and I will definitely purchase from them again.

Saia is a horrible freight company. I used to deal with them at my previous job as a shipper. Box had a little damage, paint is rubbed off in a couple areas and swivel wheel assembly was bent. I was able to get it straight. Hopefully it will roll ok once it has weight on it. Not something I would expect for a $1500 item. I had to call Saia several times because I was getting a runaround on the delivery, they kept telling me they would schedule a delivery time. Never did, it showed up at my house unexpected, luckily my wife was still home. Seems like a good product though
