6 Description of the Pump
In an average household, around 10 to 20% of the energy consumption is caused by common
standard pumps. The Delta Plus pump can reduce energy consumption by up to 80% compared
to a standard circulation pump, whilst maintaining the same level of hydraulic power. The pump
output can be adjusted to the actual needs of the system, as it works according to the propor-
tional pressure process.
