Integrated systems and services that reduce total cost of ownership

In designing modern desalination plants, cost-effective water production, energy consumption and system availability are major drivers. Our ability to deliver complete, integrated flow control systems that are energy-efficient and scalable enables desalination plants to operate economically and grow with demand.


Regardless of the desalination process, Flowserve supports customers with specialty equipment and aftermarket services to advance plant operating goals and keep key flow control processes running smoothly.


Flowserve offers:


  • Unparalleled experience in the design and operation of high-efficiency fluid motion and control systems.
  • Single point of contact and responsibility for all major equipment, including pumps, energy recovery devices, valves and mechanical seals.
  • Equipment and system optimization to provide the lowest total cost solution.
  • Engineering and technical resources for application support and ongoing life cycle cost-reduction services.
  • Local support of parts, repairs and service through nearly 200 global Quick Response Centers.
  • Condition monitoring and maintenance contracts that guarantee availability and efficiency of equipment.
  • Educational services that train customer personnel in the selection, operation and maintenance of pumps, energy recovery devices, seals and valves.

Experience That Counts

Flowserve equipment is installed in some of the biggest desalination plants in the world and more than two-thirds of the mega SWRO projects use Flowserve pumps and ERDs.

Reverse osmosis desalination

Energy consumption is generally the biggest operating cost driver of RO desalination. Advances in membrane and energy recovery technologies are making SWRO and brackish water reverse osmosis (BWRO) more economical, but it can’t be taken for granted.


We understand RO plants consume a lot of power, much of it by high pressure pumps, so we build optimal efficiency into every one of our RO systems. Our high-pressure membrane feed pumps and ERDs — including Flowserve FLEX™, Calder® DWEER™ isobaric devices and Calder ERT energy recovery turbines — feature optimized hydraulics and advanced material technologies to keep operating costs low and plants running profitably. Moreover, our detailed systems knowledge along with a full menu of technical support services are available wherever and whenever needed to ensure plant availability goals are met.

Multistage flash distillation (MSF) and multi-effect distillation (MED)

Thermal desalination via MSF or MED is most economically advantageous where water salinity is very high. Selecting equipment and materials that can survive elevated brine temperatures and salinity is critical to the success of these plants. Pitting, crevice corrosion and stress corrosion cracking are major challenges in processing seawater and brackish water.


Flowserve is unmatched in materials expertise and applications know-how. Our pumps and valves are available in a broad range of corrosion-resistant materials — both metallic and non-metallic — to provide a competitive total cost solution for the corrosive services found in MSF and MED desalination plants.


Flowserve Beats Performance Demands of Desalination Plant Upgrade

The Cyprus Water Department needed to improve the efficiency of the Larnaca Desalination Plant to offset increasing energy costs. By upgrading the plant with state-of-the-art technologies, including improved high-pressure pumps and DWEER ERDs, Flowserve was able to beat their performance goals.

Understanding the business of desalination

We’ve worked with government-backed fixed engineering, procurement and commissioning (EPC) projects as well as privately financed build-own operate (BOO) and build-own-operate-transfer (BOOT) ventures. Our dedicated desalination experts and project managers understand the business challenges of each commercial model.


For new projects or major upgrades, our dedicated global project managers and engineering experts help streamline execution. They offer a total solution approach, focused on creating the most efficient and technologically advanced systems. They work with your teams to select equipment, maximize overall efficiency, and optimize plant layout. And, they also work tirelessly to ensure installation and commissioning meet requirements and schedules.


For existing operations, we’ve invested in aftermarket services and supporting infrastructure to help plant operators manage risks. Our turnkey maintenance contracts guarantee minimum efficiencies of key equipment. Monitoring and preventative maintenance service plans make sure plant availability and throughput goals are achieved.

A complete, integrated flow control system

By bringing together industry-leading pumps and valves, high-efficiency ERDs, unmatched materials expertise and desalination-specific application knowledge, Flowserve is a single-source provider of complete, integrated flow control systems for desalination plants around the world.


Having equipped water desalination plants for more than a half-century, we have the equipment and system expertise to meet these challenges.
