Flygt Leakage

Product introduction

This is the original Xylem‑Flygt leakage sensor kit for submersible sewage pumps, including FLS float‑type leakage sensors and CLS oil‑chamber water‑in‑oil sensor.

Main function

These sensors are installed inside submersible pump cavities (stator housing, junction box, oil chamber / leakage chamber).

Once water penetrates into the pump interior due to mechanical‑seal failure, the leakage sensor will send out alarm signals to the pump monitoring system (MAS‑801, MAS‑711, MiniCAS‑II, SmartRun, MultiSmart). It triggers warning or emergency pump stop, to avoid motor burnout caused by water ingress.

Introduction

Float Switches for Leakage Protection - FLS/FLS10

Submersible machines face exposure to leakage risks. That's why we equip pumps and mixers with leakage detectors for protection and early warnings.

Leakage from the hydraulic end through the seals is detected by using float switches of type FLS or FLS10. These sensors are incorporated in the stator housing or inspection chamber. The same type of sensors are used to protect from water ingress through bushings or cables into the junction box.

Water in Oil Sensor – CLS

Pumps with oil housings can be fitted with a water in oil sensor called CLS. It detects and warns for a water in oil content exceeding 35%. This initiates oil service. At a point when the interval between service occasions becomes short, the seal should be changed.
