Energy Recovery Inc., a company that produces energy recovery devices for desalination, recently launched its new Aqua line of high-pressure desalination pumps – the AquaBold multi-stage reverse osmosis (RO) high-pressure pump and the AquaSpire single-stage pumps.

The pumps, which ERI obtained with its acquisition of Pump Engineering, LLC and re-engineered, offer nearly 90 percent efficiencies, and complement the company’s product suite of isobaric and centrifugal energy recovery technologies.

The AquaBold high-pressure seawater pump has been optimized for quality, reliability, and durability, and offers enhanced corrosion resistance. A unique new internal component protection system acts as an “anti-crash” feature similar to those found in cars that protect internal components in the event of damage to the pump, offering an elevated level of reliability. Additionally, the new and improved bearing and debris durability increases the lifecycle of the pump and reduces the need for maintenance. Both pumps include process lubricated thrust bearing technology, helping to eliminate efficiency losses.

The AquaSpire high-pressure single-stage seawater or brackish water pump contains ERI’s patented Volute Insert Technology, which allows the custom hydraulics of the pump to be adjusted should system conditions change in the future, such as plant expansions.

ERI acquired the pump product line in December of 2009 and optimized and enhanced them to reduce energy consumption and increase efficiency in specific process conditions.
