Hydrolevel 250 Pump Controller

The Hydrolevel 45-250 (Safgard 250) is a heavy-duty 120Vac combination pump controller and low water cut-off engineered specifically for steam boiler applications with operating pressures up to 250 PSI. As a veteran-preferred solution for maintaining precise boiler water level control, this unit utilizes EL1214 sensing probes and a durable manifold casting to manage the feed pump. By eliminating moving parts within the boiler water, it mitigates common failure points such as float scaling or mechanical hang-ups. The burner circuit automatically opens if the water level falls below the bottom probe, providing critical protection against dry-fire conditions, and resets immediately once the water level returns to a safe operating range between the middle and upper probes. Designed for installation in a 1-inch equalizing line, the Safgard 250 ensures high-pressure steam systems remain balanced and operational, making it a staple for contractors prioritizing system longevity and electronic low water cut-off reliability over traditional mechanical controls.

• No Moving Parts: Electronic probe technology prevents sediment-related mechanical failures and eliminates the need for float rebuilding.
• Integrated Control: Dual-function design manages both the boiler feed pump and the burner safety circuit in one 120V enclosure.
• High-Pressure Rating: Rated for steam systems up to 250 PSI, suitable for commercial and industrial 120V pump control applications.
• Automatic Reset: Streamlines recovery after a low-water event by automatically restoring the burner circuit once levels normalize.
• Simplified Maintenance: Rugged manifold casting with three EL1214 probes allows for straightforward sensor inspection and annual cleaning.

Can this be used as a secondary low water cut-off?
No, the Hydrolevel 250 is designed to act as the primary low water cut-off and pump controller. Commercial steam systems often require a separate, manual-reset secondary control to meet local codes.

Does this unit require a relay for the feed pump?
Yes, the Safgard 250 is a pilot duty control. To prevent internal damage, you must install a power relay or motor starter between the control and the condensate pump or burner circuit.

What maintenance is required for the sensing probes?
Regular blow-downs are essential to prevent sediment build-up in the manifold. Additionally, probes should be removed and cleaned annually to ensure the electronic signal remains unobstructed.
