CPP Product Details

Weight Operated Leak Detector with Split Housing Adapter

The Weight Operated Leak Detector with Split Housing Adapter is engineered to capture and manage fluid leaking past stuffing box packing, helping operators prevent spills, protect equipment, and maintain safer production operations. This system operates by monitoring the accumulated weight of fluid collected in the stainless steel reservoir. Once the preset weight is reached, the electrical switch automatically shuts down the pumping unit to prevent overflow and environmental contamination.

Available in explosion-proof and non-explosion-proof configurations, the leak detector features an adjustable spring mechanism that allows operators to fine-tune the activation point for specific operating conditions. Paired with APT’s Split Housing Adapter, the system easily adapts to bolt-style stuffing boxes and can be installed without the need for a rig, reducing downtime and installation costs.
