Engineering Note: The PX-L220 combines the L-series high-flow capacity (220 gpm (49.9 m³/h)) with low-pressure optimization up to 450 psi (31 bar). Ideal for large brackish water desalination trains, municipal water reuse, and industrial process water applications where energy recovery at lower operating pressures is required.
