Better Built with Quality Components

Contact EPRO for Replacement Parts for All Makes of Systems

Part of what distinguishes EPRO RO Systems are the parts we select. Every system is hand built in the USA using high quality, NSF-certified components that meet our stringent engineering requirements.

Multistage Centrifugal Pumps

Every EPRO RO system uses a heavy-duty, multistage centrifugal pump. It’s the heart of the system, which is why we choose rugged, reliable pumps that are made in the USA. They feature a corrosion-resistant, stainless steel lower section and run extremely quietly. And, they’re always in stock.

Tough Pressure Vessels

For the system to get the EPRO stamp of approval, every component needs to measure up. That even includes the pressure vessels we choose. They feature end caps that are reinforced with a stainless steel insert to prevent splitting. Like all our parts, you’ll find them in stock every day.

316 Stainless Steel Fittings

While many RO manufacturers use lesser Type 304 stainless steel valves and fittings, we insist on Type 316 stainless steel for these critical components. With 18% chromium and 10%, it offers increased resistance to corrosion – for more dependable operation. And, we always keep them in stock.

Braided Stainless Steel Hoses

These durable, stainless steel braided hoses are one of the quality features that set EPRO RO systems apart. We insist on them for long term performance. They’re more resistant to UV light and wear & tear, and feature standard NPT fittings. Plus, you’ll find them in-stock if you need one.
