Conventional Fire-Pump Isolation Skid
Purpose
Keep raw sediment and test slurry out of a conventional engine's main pump while retaining the engine as a clean-water source in approved research configurations.
Operating concept
A clean-water inlet from the owner-approved apparatus feeds a physically separated downstream injection skid; check valves, isolation, and a break/containment strategy prevent solids backflow.
Key assemblies
clean-water inlet; double isolation/check arrangement; backflow monitoring; injection connection; pressure relief; drain/containment tray; water-only outlet; owner lockout interface
Operating sequence
obtain equipment-owner approval → connect clean-water path → verify backflow protection → run baseline → enable separate slurry injection → monitor separation → disable injection and flush before disconnect
Instrumentation
intake/discharge pressure; flow; vibration or motor load; bypass state
Safeguards
pressure relief; rated hose/couplings; isolation and depressurization; wear inspection points
Failure modes and mitigations
backflow into pump; overpressure; wrong coupling; operator mode confusion; residual solids at disconnect
Variants
portable skid; apparatus sidecar; fixed training-loop interface; dual- check monitored spool; air-gap tank-fed concept
Validation gates
closed-loop pressure test; leak/coupling review; abrasion trial; fail- safe bypass and purge
Claim boundary
CLAIM BOUNDARY: No certified design, validated recipe, performance guarantee, regulatory approval, or authorization for uncontrolled-fire use is represented.
Unverified concept for qualified research. Not certified equipment, not a validated formula, not fabrication instructions, and not authorization for active-fire use. Individual conventional components are not claimed as separately invented.
