The Wilo dual-pump management makes you forget the tedious setting up of double pumps.

Depending on the application, operation runs with a main and a standby pump (redundant operation) or with a base-load and a peak-load pump (parallel operation). Pumps are changed over or additionally activated automatically depending on the load or fault state. Another advantage is that the double pump in building automation can be handled as a system which is as simple as a single pump. This saves engineering efforts. Furthermore, energy may be saved: Wilo knows exactly when the operation of both pumps at lower speed is more economical than one pump at higher speed.
