PRODUCT OVERVIEW

250 LPM, with pattern control.

The 38 mm Constant Flow Nozzle combines a stated 250 LPM discharge with a straight-stream-to-wide-fog pattern. A pistol grip and bale-operated ball valve provide manual handling and shut-off on a 1½″ handline connection.

The hard anodized aluminium alloy body is supported by a nitrile rubber bumper and precision fog teeth. The catalogue describes pressure compensation within the designed operating range; confirm the permissible pressure range and selected inlet connection with your quotation.

INSPECTION & MAINTENANCE

Keep the nozzle
ready for service.

The product catalogue sets out the following inspection and care guidance. Keep the original document with your equipment records.

01Inspection before use

Inspect the body for damage or corrosion, and check the inlet coupling, locking lugs, fasteners and retaining pins.
Verify smooth movement of the bale handle and pattern control ring.
Check O-rings and rubber seals for cuts, wear or deformation.

02Cleaning and lubrication

Flush with clean fresh water after use, especially following foam, sea water, chemical or contaminated-water exposure. Work through the spray patterns while flushing.
Clean the exterior with a soft cloth. Avoid abrasive cleaners, steel brushes and aggressive solvents.
Apply a light coating of silicone-based or manufacturer-approved lubricant to the pattern ring, bale pivot points and moving joints. Avoid excess lubricant.
Do not lubricate the discharge or internal flow passages.

03Functional checks

Check for leakage at the inlet and shut-off valve, and verify smooth opening and closing.
Verify flow performance at the rated operating pressure and a uniform discharge across the pattern settings.
Test the nozzle after maintenance before returning it to operational service.

04Storage and replacement parts

Drain the nozzle and store it in a clean, dry, ventilated location, protected from sunlight, dust and corrosive chemicals.
Keep inlet protective caps fitted and protect the nozzle from impact or heavy loads.
Replace worn seals, gaskets, pins, handles or coupling components with genuine Frozenfire parts.

05Maintenance precautions

Completely depressurise the hose line before inspection or maintenance. Never dismantle a nozzle connected to a pressurised supply.
Do not modify components. Replace damaged parts promptly and have routine maintenance carried out by trained personnel.

Recommended inspection intervals
