If the primary pumping diaphragm fails, this modular, watertight unit senses conductive changes if liquid enters the isolation chamber of the pump. Warning lights indicate which side of the pump is tainted. The unit can also be wired for audible alarm or pump shutdown. Low voltage. Simple installation.
Visual Leak Detector
A sight tube style leak detector is installed on each driver chamber. If a pumping diaphragm break occurs, liquid in the sight tube changes.
This type of leak detection is standard construction on all aluminum ET and S Non-Metallic spill prevention pumps.
Mechanical Leak Detector
When a leak chemically attacks an internal o-ring on this detector, it actuates a plunger. This opens an air valve, which in turn activates a customer-supplied solenoid (or similar device) to trigger a signal.
For use with the RuppGUARD™ Spill Prevention SANDPIPER® pumps.
