The PX Q650 pressure exchanger is an energy recovery device designed to meet the scale, efficiency, and reliability requirements of the desalination industry. As part of Energy Recovery’s PX® Pressure Exchanger® portfolio, the PX Q650 delivers higher flow capacity and efficiency with lower mixing, all while maintaining the durability and reliability customers know and trust.

Engineered with a patented corrosion-resistant ceramic core and a single moving part, the PX Q650 minimizes total cost of ownership across diverse operating conditions and can reduce a plant’s reverse osmosis energy use by up to 60%. With no scheduled maintenance required and a 30-year design life, it delivers high uptime and long-term reliability. Its flexible design and straightforward installation make it well-suited for both new facilities and retrofit applications.

The PX Q650 offers a flow capacity of 56.8 to 147.6 m³/hr (250 to 650 gpm) and operates at pressures up to 83 bar (1,200 psi). It achieves up to 99% peak efficiency, with volumetric mixing as low as 2%.
