    Spill-STOP Leak Containment System - Not Just Leak Detection!

    Diaphragm failure of your Air Operated Diaphragm Pump allows process fluid to escape from the pump's air exhaust port. Unmonitored, the spill can create an extreme expense for your company in lost product, material cleanup, and EPA reporting.

    The patented Spill-STOP Leak Containment System prevents costly and hazardous spills caused by pump diaphragm failure. The Spill-STOP's patented design safely captures leaked product while effectively shutting down failing pumps. Optional warning alarm and backup pump switchover further ensures maximum productivity and minimal system downtime.
