To ensure safe operation, always use layflat hoses within their rated working pressure, not their burst pressure. Burst pressure is a safety factor only and must never be used for hose selection.
The burst pressure is the maximum pressure the hose can withstand before failure, but it should never be used as a guide for regular operation. Always select hose based on Working Pressure (WP), not burst pressure.
To determine the pressure your hose must handle, consider:
• Vertical lift (static head) Water pressure increases by approx. 1 bar per 10 m of lift.
• Pump discharge pressure The pressure your pump produces at the operating flow rate.
• Friction loss Caused by hose length, internal diameter, fittings and flow velocity.
• Pressure surges Created when pumps start or stop suddenly or when valves are closed quickly.
For high head heights, long hose runs or aggressive pump cycles, always select a higher pressure rated hose.
Regularly inspect hoses for wear, kinks, and signs of damage, and avoid sharp bends or dragging over rough surfaces while under pressure.
