Magnetic Boiler Water Level Controller & Dual Switch Unit

About this part

Industrial glandless magnetic boiler water level controller engineered for direct boiler shell or external chamber mounting. Utilizes magnetic repulsion between internal stainless steel float magnets and external switch magnets across a solid non-magnetic pressure tube, completely eliminating packing glands and leakage risks. Controls feed pump on/off sequencing and triggers primary/secondary low-water safety alarms and burner cutoffs.

Key features

• Glandless, leak-proof magnetic operation designed for high steam pressures and temperatures
• Dual independent snap-action switch mechanisms for pump control and low water cutoff
• Mechanical level index scale for instant visual confirmation of internal float position
• Cast steel / ductile iron pressure body rated for continuous boiler duty
• Available in configurations designed for applicable British or ASME boiler safety requirements; verify certification for the exact model

Typical applications and wear

Fire tube steam boilers, biomass boilers, and waste heat recovery units. Wear results from sediment accumulation around the float pivot and switch contact cycling.

Compliance

Supports documented boiler water-level protection; licensing, insurance, and inspector requirements depend on the jurisdiction and exact installation.
