Estas bombas incorporan un impulsor semiabierto con un paso libre de 10 mm y son aptas para bombear:
|
El diseño compacto de estas bombas hace que resulten aptas para su uso en instalaciones tanto provisionales como fijas.
Las bombas están fabricadas en hierro fundido e incorporan un puerto de descarga y un motor trifásico sumergible con una carcasa hermética con aislamiento de clase F (155 °C).
Asimismo, también incluyen un puerto de descarga lateral y un cierre mecánico doble.
Pueden instalarse tanto de forma independiente como en sistemas con acoplamiento automático.
Estas bombas cuentan con un sensor de temperatura bimetálico que protege el motor frente al sobrecalentamiento.
Además, tienen un cable de 10 m.
