Integrated Non-Return Valve Factory-fitted check valve prevents backflow, eliminating the need for separate installation and reducing system complexity.
Internal Pressure Membrane Integrated membrane provides smooth pressure response and reduces pump cycling for extended equipment life.
Pressure Gauge Visual pressure indication allows easy monitoring of system pressure at a glance.
Dual Voltage Operation Works with both 115 VAC and 230 VAC power supplies (50/60 Hz), providing installation flexibility worldwide.
Alarm Indication LED alarm indicator alerts users to fault conditions requiring attention.
Anti-Jam Function Prevents impeller seizure during periods of inactivity by automatically exercising the pump.
Automatic Restart Resumes normal operation automatically after fault conditions are cleared, minimising downtime.
Self-Priming Function Assists pump priming for reliable startup in self-priming pump installations.
