Uptime matters. We design our line of high-pressure membrane feed and PX circulation pumps specifically for seawater reverse osmosis (SWRO) desalination applications. We use corrosion-resistant material, yielding a long and reliable service life. When combined with our ERDs, our pump solutions offer you reliable solutions to generate cost savings through high productivity and efficiency. Energy Recovery’s range of pumps features the same precision engineering and high-quality standards as our leading energy recovery devices. Our customers trust them to provide improved productivity and optimized operations in high-pressure operating environments.

High-Pressure Pumps

Pressure is the essential driving force for SWRO desalination. In this process, high-pressure pumps pump the seawater to pressures required by the reverse osmosis membranes. Our high-pressure pumps can deliver pressures up to 83 bar (1200psi). We design them specifically for a SWRO desalination plant’s demanding operating conditions and environment using corrosion-resistant stainless steel alloys.



The AquaBold™ high-pressure pump is a multi-stage centrifugal pump ideal for small- to medium-scale reverse osmosis systems with flows from 25 to 272 m3/h (100-1,200 GPM) and pressures up to 83 bar (1,200 psi). 


The AquaSpire is a single-stage, high-pressure pump made for medium- to large-scale seawater and brackish water reverse osmosis systems, handling flows from 57 to 2,725 m3/h (250 to 12,000 GPM) and pressures up to 45 bar (600 psi). 

Circulation Pumps for PX® Pressure Exchanger®

Low-Flow Horizontal Pumps

Our low-flow horizontal pumps pair with our PX devices for SWRO trains with permeate production rates ranging from approximately 135 to 1,350 m3/day (35K to 356K GPD) 

High-Flow Vertical Pumps

Our high-flow vertical pumps target SWRO plants with permeate production rates ranging from 640 to 10,000 m³/day (168K to 2.64M GPD). To optimize energy recovery, our circulation pumps pair with our PXs [link to page] for an end-to-end energy recovery solution that maximizes efficiency and cost savings.
