Flygt ENM-10 Non-Mercury Pump Control Float Switch

The Flygt ENM-10 Non-Mercury Pump Control Float Switch is a reliable liquid level regulator/float switch designed for water and wastewater tanks, available with 20, 40, or 65-foot cables. Housed in a smooth, waterproof teardrop-shaped casing, it resists deposits and impurities. Suspended by its cable, the float tilts with rising liquid levels, triggering a mechanical micro switch (SPDT, 250 VAC/10A) to start/stop pumps or activate alarms. It can be wired normally open or closed and is typically mounted on an adjustable bracket in lift station pits for customizable level control.

Flygt MiniCAS II Pump Monitoring Relay

The Flygt MiniCAS II Pump Monitoring Relay is a compact, high-performance monitoring relay designed to protect small and medium-sized pumps and mixers from overheating and seal leakage. It monitors thermal switches and supports various leakage sensors—including FLS, FLS10, and CLS—to detect faults early and prevent damage. Upon detecting an issue, it stops the pump or triggers alerts via lamps and relays. Supporting up to two leakage sensors, MiniCAS II offers reliable protection and integrates seamlessly with MultiSmart and SmartRun systems, making it a versatile solution for minimizing pump downtime and maintenance costs.

FAQs

1. What is the purpose of a float switch in a waterworks system?

A float switch is a device used to detect the level of liquid within a tank or reservoir and automatically control the operation of pumps, valves, or alarms. In waterworks systems, float switches help prevent overflow, dry running of pumps, and ensure consistent water levels, making them crucial for water tank management, wastewater treatment, and irrigation systems.

2. How do float switches differ from pressure switches in water applications?

Float switches operate based on liquid level changes, using a floating mechanism that rises or falls with the water, while pressure switches detect water pressure and activate at set thresholds. Float switches are more accurate for controlling liquid levels, whereas pressure switches are better for detecting line pressure, making them suited for different roles within the same waterworks system.

3. Can float switches be used in both clean and dirty water?

Yes, but the type of float switch used matters. For clean water, standard float switches are sufficient, while in dirty or wastewater applications, heavy-duty or encapsulated float switches with protective housings are recommended to prevent fouling and ensure reliable operation in sludge or high-solid environments.

4. Why are multiple float switches sometimes installed in one tank?

Multiple float switches are used to manage different control points such as low-level cutoff, pump start, high-level alarm, and emergency shutdown. This layered approach ensures redundancy and more precise control, especially in critical waterworks applications where overflow or pump failure can lead to damage or service disruption.

5. What are the key materials to consider when choosing a float switch for water systems?

Material compatibility with the liquid is essential. Common float switch materials include polypropylene, stainless steel, and PVC. For potable water, food-grade plastic is often preferred, while stainless steel is ideal for corrosive or high-temperature environments to ensure durability and hygiene.
