The Graco 25F108 Leak Sense Kit helps protect compatible QUANTM™ electric diaphragm pumps by detecting diaphragm leaks and automatically stopping pump operation to reduce damage and downtime.
The Graco 25F108 Kit, Accessory, Leak Sense is designed for use with compatible Graco QUANTM™ Electric Double Diaphragm Pumps installed in standard (non-hazardous) environments. It helps detect diaphragm leaks and automatically stops the pump to help prevent product contamination and equipment damage.
The Graco 25F108 Kit, Accessory, Leak Sense is a genuine OEM leak detection accessory designed to enhance the safety and reliability of compatible QUANTM™ electric diaphragm pumps. The system continuously monitors the pump's leak chamber for fluid caused by diaphragm wear or failure.
When a leak is detected, the sensor communicates with the pump control system, causing the status indicator to flash and automatically stopping pump operation. This helps minimize downtime, reduce maintenance costs, and protect both the equipment and the material being transferred.
