Leo LVR3-7 / 0.55KW 400V Vertical Multistage Pump And Motor
10499
Introducing the LEO LVR3-7, a reliable cast iron vertical multistage pump built for light commercial and agricultural irrigation applications. Offering a flow range of 2~5.5 m3/h, it delivers reliable pressure and flow across its multistage impeller design. A cast iron base and cover deliver structural robustness, complemented by stainless steel wetted components for extended pump life.
