Waterstry SB IE3 – несамовсасывающие вертикальные многоступенчатые центробежные насосы. Доступны модификации с фланцевым/муфтовым и овально резьбовым присоединениями. Насосная часть состоит из основания и головной части, между которыми располагается набор камер на валу, заключенный во внешний кожух. Вся конструкция стягивается при помощи распорных болтов. Основание имеет всасывающий и напорный патрубки равного диаметра, расположенные на одном уровне по схеме in-line, что облегчает монтаж насоса непосредственно в разрыв трубы. Все насосы оснащены необслуживаемым механическим торцевым уплотнением картриджного типа.
