Designed for maximum efficiency, the PX consumes no electrical power, enabling SWRO facilities to reduce their energy consumption by as much as 60%.
With no scheduled maintenance and proven performance for the long run, our PXs offer unbeatably low life-cycle costs.
Our range of PX capacities provides flexibility to optimize train size to specific project requirements, making the PX the ideal solution for new installations and retrofits alike.
How the PX Pressure Exchanger Works
The PX captures hydraulic energy from the high-pressure reject stream of SWRO processes. It then transfers this energy to the low-pressure feed water with up to 98% efficiency.
The PX Family
PX Q Series
The PX Q Series is the gold standard in energy recovery devices. It includes the PX Q300, PX Q260, PX Q220, PX Q180 and PX Q140.
PX Q devices offer operational sound levels below 79 decibels—comparable to a home vacuum cleaner—to enhance the safety of SWRO plant working environments through reduced audio levels.
PX Q devices provide reduction in fluid mixing, resulting in lower membrane feed salinity and pressure, and higher desalination system performance.
Up to 40 parallel PX Q devices have been successfully installed in a single train, with 10 to 16 PXs commonly installed in parallel.
PX Q devices perform with unparalleled efficiency—up to 98%.
PX S Series
The PX S series includes the following models: PX 90, PX 70, PX 45 and PX 30.
PX S devices are designed to meet the needs of small- to medium-sized plants.
PX S devices can be installed in parallel according to specific plant needs.

Superior Precision and Durability
The PX cartridges have only one moving part and are made with high-purity aluminum oxide ceramic. They’re corrosion-proof and three times more abrasion-resistant than steel. All that adds up to unmatched durability.
We design and manufacture ceramic PX components in-house at our California headquarters. This allows us to control the precision and quality of our core components down to the micrometer level, ensuring every PX device performs with maximum efficiency, durability, and reliability.
