FLYGT Sewage Pump Parts Leakage Sensor

Our proprietary brand delivers complete technical solutions for fluid machinery and engineering systems. We specialize in industrial control and drive equipment, mechanical seals, and international field engineering support.

Our ecosystem of specialized technologies and product brands gives clients access to high-level technical advisory, commercial support, and complementary product system integration — from pumps and variable frequency converters, servo drives, PLC-HMI interfaces, industrial control cabinets, and motors, to mechanical seals and assemblies, couplings, gearboxes, and turnkey engineering services (including overseas on-site 3D scanning reverse molding for pump replacement parts and equipment debugging by our dispatched engineers abroad).

FLYGT Leakage Sensor is a precision monitoring component designed to detect the presence of liquid in the pump motor chamber of FLYGT submersible sewage pumps. When moisture penetrates the motor housing seals, the sensor triggers an alarm signal to the pump control panel, enabling early intervention before winding burnout or bearing failure occurs.

Installed as a wet-to-dry contact probe, the leakage sensor is mounted in the pump's motor chamber drain hole. It is compatible with a wide range of FLYGT submersible pump models and control systems. Our replacement sensors are reverse-engineered to exact OEM specifications for plug-and-play interchangeability, requiring no controller modification.

Typical applications: municipal sewage treatment plants, industrial effluent pumping stations, building drainage systems, and flood control installations equipped with FLYGT pump monitoring infrastructure.

Leakage sensors for submersible pumps operate as conductivity probes detecting liquid presence in the motor chamber:

• Conductive Probe Sensor — Two-electrode probe; liquid bridging the electrodes closes the circuit and triggers an alarm relay in the control panel
• Capacitive Sensor — Detects changes in dielectric constant caused by liquid accumulation; suitable for detecting emulsified or low-conductivity liquids
• Float Switch Integrated Sensor — Mechanical float type for pump wet-well level monitoring; separate from motor chamber sensors
• Integrated Smart Sensor — Combined leakage + temperature monitoring probe; outputs digital signal (RS-485 / Modbus) for PLC integration

The most common replacement sensor is the conductive two-electrode probe, which requires no power supply — it operates on the conductivity of the liquid itself to complete the alarm circuit.

Replacing a FLYGT leakage sensor is straightforward:

1. Isolate Pump — Disconnect power supply and lock out/tag out before opening the pump terminal box
2. Locate Sensor — Remove the sensor from its mounting position in the motor chamber drain hole
3. Disconnect Cable — Unscrew the sensor cable connectors and note the polarity
4. Install Replacement — Insert the new sensor; reconnect cable connectors; apply thread sealant if applicable
5. Test — Restore power; manually introduce a small amount of water to the sensor area to confirm alarm activation

Sensors are available for virtually all FLYGT submersible sewage pump series. Provide your pump type designation for immediate compatibility confirmation.

For discontinued sensor models or OEM sensors with no market availability:

1. Sample Analysis — Send the original sensor or high-resolution photos; our engineers inspect the probe geometry, electrical rating, cable spec, and connector type
2. Specification Rebuild — Engineering team reconstructs the technical specification sheet including material grades, insulation class, and electrical parameters
3. Prototype & Testing — First article produced; function-tested in simulated pump motor chamber conditions
4. Production & Delivery — Batch production with 100% functional testing before shipment
