The Smart Pump N series allows customers to select the optimal model based on their application and installation conditions, with options for semi-custom processing. Additionally, models equipped with a backup function are available, enabling drainage even in the event of a failure. They can be selected for various situations, such as renovation work where slopes are difficult to achieve, basements, and temporary toilets. They are used for drainage in supermarket refrigerated display cases, handwashing sinks for convenience store health department measures, kitchen drainage in restaurants, as well as in offices, clinics, and underground single-family homes.
