The Mercury FlowGuard is a flow reduction safety device engineered specifically for the Mercury Quick Attack LE portable fire monitor. It is designed to help reduce hazard risk while providing firefighters with greater confidence during operations.


Features

  • Does Not Shut Down All Flow: Automatically reduces water flow instead of fully stopping it, maintaining controlled operation.
  • Controlled Flow Reduction: Reduces flow to approximately one-third when hazardous movement is detected.
  • Pump Protection: Prevents water hammer and protects the pump from potentially damaging sudden flow changes.
  • Automatic Response: Reduces water flow when excessive or potentially hazardous hose or monitor movement occurs while flowing.
  • Fast Reset: Restores normal operation by closing the monitor valve, turning the reset button one-quarter turn, repositioning the hose, and reopening the monitor valve.
  • Lightweight Design: Weighs only 4.6 pounds or 2 kg for easy handling and transport.
  • Compact Size: Slim profile measuring 9.125 inches or 231 mm in length for easy integration into portable setups.
  • Low Friction Loss: Produces 8 psi or less than 1 bar at 500 gpm or 1900 lpm, with total system friction loss of 14 psi or 1 bar at the same flow rate.


How Is It Used

The Mercury FlowGuard is installed between the hose line and the Mercury Quick Attack LE monitor. During operations, if excessive movement is detected while flowing, the device automatically reduces water flow. Normal flow is restored using a simple manual reset procedure.


Who Used It

The Mercury FlowGuard is used by firefighting professionals operating Mercury Quick Attack LE portable fire monitors in structural firefighting applications where controlled flow and crew safety are critical.


Maintenance Information

No specific routine maintenance procedures are required beyond standard inspection of the unit. The stainless steel valve and Pyrolite construction are designed for durability during firefighting operations.
