La pompe centrifuge non auto-amorçante, monocellulaire, est conçue selon la norme ISO 5199 avec des dimensions et une performance nominale conformes à la norme EN 733. Les brides sont PN 16 avec des dimensions conformes à EN 1092-2. La pompe possède un orifice d'aspiration axial, un orifice de refoulement radial et un arbre horizontal. La conception à coulisse arrière permet de retirer l'accouplement, le support palier et la roue sans intervention sur le moteur, le corps de pompe ou la tuyauterie. La garniture à soufflet en élastomère non équilibrée est conforme à la norme DIN EN 12756. La pompe est équipée d'un moteur ventilé asynchrone monté sur pied. La pompe et le moteur sont montés sur un châssis commun.
