The pumps were obtained as part of ERI’s acquisition of Pump Engineering, L.L.C. and have been re-engineered. ERI says they now offer offer best-in-class efficiencies (up tp 90%), and complement the company’s product suite of isobaric and centrifugal energy recovery technologies.
The ERI AquaBold and ERI AquaSpire pumps have mechanical wear of the components, and are manufactured for a 20+ year service life with little to no scheduled maintenance required. When combined, ERI’s pumps and energy recovery devices offer the highest efficiency packaged solution with minimum power consumption for desalination plants around the world.
The ERI AquaBold offers enhanced corrosion resistance and it has a new internal component protection system (ICPS)which acts as an “anti-crash” feature similar to those found in cars that protect internal components in the event of damage to the pump. It has new bearing and debris durability which increases the lifecycle of the pump and reduces the need for maintenance. The ERI AquaBold and ERI AquaSpire pumps feature process lubricated thrust bearing technology.
The ERI AquaSpire can cope with both seawater or brackish water and incorporates a patented Volute Insert Technology, which allows the custom hydraulics of the pump to be adjusted should the system conditions change in the future, such as plant expansions. This allows users to change out the lightweight internal volutes to bring the pump back to its best efficiency point (BEP).
