How to choose

Building height: The catalogue quick selection gives 406 models for 6 floors, 408 for 9 floors and 410 for 14 floors. The catalogue booster table takes 18.75 m head for 1 floor and adds 3.75 m per extra floor.
One or two pumps: COE1 has one pump. In COE2 two pumps alternate, so the building keeps water while one is serviced.
Power supply: M models are single-phase, T models three-phase. The 410 is three-phase only; the 408 comes in both.
Connections: COE1 pump ports are DNA 1¼" / DNM 1"; COE2 manifolds are DNC 2" / DNB 1½".

What is the difference between COE1-MSV and COE2-MSV?

COE1 has one pump. COE2 has two MSV pumps that alternate in rotation, and the manifold connections are larger (DNC 2" / DNB 1½").

Is the control panel included?

Yes. Both types come with an Xtreme panel, one pressure switch per pump and one level float switch.

Which model for how many floors?

The catalogue quick selection lists 406 models for 6 floors, 408 for 9 floors and 410 for 14 floors. Confirm the final choice on the pump curve with the required head and flow.

Can it be used for fire-fighting?

The catalogue lists fire-fighting as an application; check the regulatory requirements for the fire installation separately.
