The Siflo 150L sewage lifting pump features a sealed tank with 150L effective volume and dual-pump redundancy design, significantly reducing start-stop cycles compared to smaller units and extending the lifespan of key components. The two pumps serve as backups for each other, ensuring continuous drainage even if one pump fails. An integrated control panel supports manual/auto mode switching and fault alarm, while the float switch enables unattended automatic operation. The unit is equipped with 4 × DN100 inlets, 1 × DN100/40 reducer inlet, 2 × DN100 outlets, and 1 × DN50 ventilation port, meeting the demands of multi-point sewage collection and efficient discharge. With low operating noise and no civil works required, it is ideal for high-frequency, high-flow applications such as large basements, public restrooms, and laundry rooms, as well as a hygienic and cost-effective solution for deep renovations of old buildings.
