Diseño de la bomba
Las bombas sumergibles SP de Grundfos presentan
componentes que contribuyen a un mayor desempe-
ño y durabilidad de la gama.
Menores costos de instalación
El acero inoxidable representa una menor peso que
facilita el manejo de las bombas, resultando en me-
nores costos del equipo y menor tiempo de instala-
ción y mantenimiento.
