FLB40 4 HP ThreePhase Water Pump A heavyduty 4 HP (3 kW) centrifugal pump designed for continuous water circulation, transfer, and pressure boosting in commercial and industrial settings. Built for reliable 24 hour operation with robust materials and easy maintenance features. Key benefits flow and lift: Delivers up to 48 m3/h with a maximum head of 18 m, and supports a 2 to 3 m suction lift for effective water intake from tanks or pools. Reliable continuous operation: 100 percent copper wire motor rated for 24 hour running and available for threephase 220 V or 380 V systems. Leak prevention and long life: Silicone sealing ring covers all watercontacting sections to minimize leakage and maintain system integrity. Easy maintenance: Tool filter cover design allows fast access and cleaning of the strainer, reducing downtime. Durable construction: Engineering plastic pump body resists weather exposure, an antirust castaluminum motor cover provides fast heat dissipation, and a PPO plasticsteel impeller resists temperature and corrosion. Protection level IP55: Designed for outdoor and demanding environments with a leak style. Specifications Model: FLB40 Power: 4 HP (3 kW) Voltage: 220 V or 380 V, threephase Frequency: 50 Hz or 60 Hz Maximum head: 18 m Maximum flow: 48 m3/h Port size: 90 mm Motor: 100 percent copper wire Medium temperature range: 5 C to 50 C Protection level: IP55 Suction lift: 2 to 3 m Weight: 26 kg Typical applications Pool circulation and filtration: Continuous circulation and filtration for residential or commercial pools, with easy filter access for routine cleaning. Agricultural irrigation and water transfer: Reliable water delivery for localized irrigation, greenhouse watering, and transfer from wells or storage tanks. Water supply and pressure boosting: Smallscale building water supply, boost systems for pressure maintenance, and industrial recirculation systems. What makes it stand out Combines performance hydraulics with corrosionresistant materials for long service life. Tool maintenance and comprehensive sealing reduce operational interruptions and water loss. Flexible voltage options and threephase design suit a range of industrial and commercial installations.
