Blacoh SPS-21-2-W-E-3-AT Spill Containment System

BLACOH SPILLSTOP SPS-21-2-W-E-3-AT is a pneumatically operated spill containment system designed for 2‑inch AODD pumps. It mounts on the pump’s exhaust port to capture any liquid expelled by a diaphragm failure and keep it contained within the unit. As liquid collects, a float rises and actuates a shutoff valve that cuts the air supply to the pump, halting operation automatically. The system is configured to run from a regulated shop‑air line, typically via the provided 50 PSIG regulator, and the model designation indicates a 60–80 PSI operating range. The SPS‑21 family carries EC/ATEX certification for use in potentially explosive atmospheres (Group II, Category 2 GD), with conformity to relevant non‑electrical standards such as EN‑13463‑1 and EN‑13463‑5. This configuration supports AODD pump discharge sizes from 1/4 inch to 4 inches, making it suitable for a range of pump sizes and process liquids. Optional accessories include a warning whistle, electrical switch, or additional shutoff valves for backup pumps, enabling integrated spill prevention in multi‑pump or higher‑risk environments. By containing the spill at the source, SPILLSTOP provides a dedicated first line of defense for diaphragm leaks, supporting safer and cleaner operations in hazardous or contamination‑sensitive settings.
