Membrane Pressure Vessels

Membrane Pressure Vessels

Pure Aqua produces the finest pressure vessels that are designed to handle the highest pressure required by membranes today during treatment operations. These pressure vessels are coated with highly durable fiberglass and incorporate end caps for longer life usage in the face of corrosive conditions.

We ensure that our membrane pressure vessels are easily installed and maintained with little effort, including being painted in order to prevent the growth of algae and other biological organisms. Check out the following list of brands in order to find the right pressure vessel for your application, in addition to learning other benefits down in our advantages section.

Pure Aqua has over 20 years of experience as a global provider of top-quality membrane pressure vessels that are specifically designed to allow RO membranes to withstand high pressure water treatment applications. These pressure vessels are reinforced in fiberglass housings, which greatly increase the strength and durability of the membranes.

Membrane pressure vessels are designed for constant use as a housing for membrane elements. Vessel has been designed to meet the standards of the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section X. At an additional cost, vessels can be checked during fabrication by an ASME Authorized Inspector and Code stamped. Pure Aqua stocks a large quantity of 2.5", 4" and 8" membrane pressure vessels that range in pressure from 300psi all the way up to 1000psi for high pressure membrane systems. Each membrane pressure vessel comes with mounting pads, straps, hardware and also both end caps. All of the membrane pressure vessels offered by Pure Aqua are capable of handling even the harshest of conditions. Protec, Codeline and ROPV are all product lines that Pure Aqua stocks and offers its customers. 

Water treatment systems depend on the provision of secure, long-lasting, and clean membrane pressure vessels as housings for their elements. The membrane pressure vessels within Pure Aqua’s listings are capable of filtering using reverse osmosis or NF treatment or other types of filtration systems. These vessels maintain the texture and conciseness resilience that Pure Aqua dreams up to.

The membrane housing is by far one of the most vital parts within the reverse osmosis system process and our pressure vessels are designed to provide maximum performance in protecting your membrane. The features down below exemplify the benefits of our membrane pressure vessels and their ability to handle the highest pressures necessitated for reverse osmosis.
