Rodelta NSM
The pump type NSM is a vertical overhung, close coupled pump. The hydraulics comply with and exceed the hydraulic design parameters stated in EN733 (ISO 2858). These pumps are suitable of clean or slightly contaminated liquids. For heads above 45m at 1450rpm a number of sizes are available with a second stage, and include a diffuser to gently guide the flow from the first stage to the second. This design is available with bearing housing and is close coupled for use where space is restricted.
