Intelligent Constant Pressure Operation
The integrated VFD and pressure-control system automatically responds to changing water demand. As water outlets are opened or closed, the pump adjusts its operating speed to help maintain consistent system pressure instead of simply operating continuously at full speed.
This provides a convenient automatic water-pressure solution for homes and smaller commercial installations where water demand varies throughout the day.
Applications
Ideal for:
-
Domestic water pressure boosting
-
Residential water supply
-
Small commercial properties
-
Tank-to-house water supply
-
Constant-pressure water systems
-
Pressure boosting from storage tanks
-
Water transfer applications
-
General clean-water pumping
The ALGO Xstream 204H combines intelligent VFD control, a compact design, stainless steel hydraulic components and automatic constant-pressure operation to provide an efficient and dependable solution for everyday water supply and pressure boosting.
