Intelligent Constant Pressure Operation
The integrated VFD and pressure transmitter allow the Xstream 405S to automatically respond to changing water demand. As water outlets are opened or closed, the system adjusts the pump speed to help maintain the selected pressure, providing a more consistent water supply without requiring the pump to operate continuously at maximum speed.
Applications
Ideal for:
-
Domestic water pressure boosting
-
Residential water supply
-
Commercial water supply
-
Tank-to-house water supply
-
Constant-pressure water systems
-
Pressure boosting from storage tanks
-
Water transfer systems
-
General clean-water pumping
The ALGO Xstream 405S combines a 1500 W variable-speed motor, strong 55 m maximum head, stainless steel hydraulic components and intelligent constant-pressure control to provide a dependable solution for automatic water supply and pressure boosting.
