ALGO Xstream 1203S – VFD Constant Pressure Booster Pump
The ALGO Xstream 1203S is a high-performance Variable Frequency Drive (VFD) constant pressure booster pump designed to maintain stable and consistent water pressure as demand changes. Its intelligent variable-speed control automatically adjusts pump operation according to water usage, making it suitable for residential, commercial and general water pressure boosting applications.
The Xstream 1203S features a 2200 W, 220 V single-phase motor, delivering a rated flow of 10 m³/h at a rated head of 42 metres. With a maximum head of 55 metres and a maximum flow of 16 m³/h, it provides substantial water delivery for higher-demand pressure boosting systems.

Intelligent Constant Pressure Operation
The integrated VFD and pressure transmitter enable the Xstream 1203S to automatically adapt to changing water demand. As outlets are opened or closed, the pump adjusts its operating speed to help maintain the selected system pressure.
This variable-speed operation provides consistent water pressure while allowing the pump to operate according to actual demand rather than continuously running at maximum output.
Applications
Ideal for:
-
Residential water pressure boosting
-
Commercial water supply
-
Multi-outlet water systems
-
Tank-to-building water supply
-
Constant-pressure water systems
-
Pressure boosting from storage tanks
-
High-volume water transfer
-
General clean-water pumping
The ALGO Xstream 1203S combines a powerful 2200 W single-phase motor, 16 m³/h maximum flow, stainless steel hydraulic components and intelligent VFD control to provide a dependable constant-pressure solution for higher-demand water supply systems.
