Leo LVR1-11 / 0.55KW 400V Vertical Multistage Pump And Motor
10487
Introducing the LEO LVR1-11, a reliable cast iron vertical multistage pump built for residential and light commercial applications. Offering a flow range of 0.7~2.3 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.
