Leo 2AC400H / 4KW 400V Centrifugal Multistage Pump And Motor
5161
The LEO 2AC400H is a robust multistage centrifugal pump engineered for demanding water transfer and pressure boosting applications across industrial, commercial, and residential sectors. Ideal for urban water supply systems, fire fighting equipment, high-rise building pressure boosting, long-distance water transfer, and HVAC circulation, this pump delivers reliable performance wherever consistent water pressure and flow are essential.
Built with a durable cast iron pump body featuring specialized anti-rust treatment and paired with an AISI 304 stainless steel shaft, the 2AC400H withstands corrosive environments and demanding industrial use with minimal maintenance. Its energy-efficient IE2 motor incorporates low-noise, long-life bearings and copper windings, while the built-in thermal protector and IPX4-rated enclosure ensure safe operation in challenging conditions-making this multistage pump an excellent choice for garden irrigation systems, heating and cooling circulation, and any application requiring temperatures up to 60 degC.
