The ERI PX-260 (also written PX260) is a 260 GPM (59 m³/h) isobaric pressure exchanger designed for seawater reverse osmosis systems in the 15,000–35,000 GPD range. Standard PX series delivers 97%+ pressure transfer efficiency, cutting SWRO energy by 55-60%. The PX-260 contains a single ceramic rotor that spins hydraulically (no motor) at 1,200-1,800 RPM. As the rotor spins, axial channels alternately fill with low-pressure feed water and high-pressure brine. The pressure transfers directly fluid-to-fluid, recovering the high-pressure brine energy and pressurizing incoming feed at 97% efficiency. This eliminates the need for the high-pressure pump to handle the full feed flow — only the permeate fraction (~40%).
