Pros and Cons:
+ Two pumps: if one fails, the other takes over — 100% redundancy
+ Submergible reservoir with integrated ball check valve
+ Vortex impeller with 45 mm free passage
+ Alternating operation distributes operating hours evenly across both pumps
- Installation work for DN 80/100 pressure pipe required
Dual-pump lifting station for reliable drainage:
In an apartment complex, hospitality establishment, office, or care facility, wastewater drainage simply cannot fail. That's why there's the HOMA Sanistar dual-pump version: two vortex pumps in one submergible reservoir, with automatic alternating operation. If one pump fails or an extra large volume of water arrives at once, the second pump simply continues to run — the standard often mandates such a dual version for utility buildings.
The sizing works the same as with the single-pump series: the 205 as a base (13 m / 32 m³/hour), the 210 and 220 for more volume, and the 230 D for the highest delivery head (15.5 m). Control via pneumatic level switching with a separate control panel.
Scope of supply:
Reservoir with 2 pumps, ball check valve, elastic adapter piece, connection set for pressure pipe, pneumatic level switching, control panel; pump cable 3 m, control panel cable 0.8 m.
