Membrane Housing 8040

Protect Your RO Membranes with Industrial-Grade Housing

Tired of membrane housing leaks, corrosion, or poor flow? Our 8040 FRP membrane housing is built for durability: 100,000 cyclic pressure tests, UV-resistant coating, and precision sealing-ideal for high-pressure RO systems (300-2000PSI). Choose an end/side entry with a 1-8 element capacity to fit your water treatment setup. 

Suitable for RO membrane model 8040.

Why Our Housing Stands Out?

• Smooth Inner Surface: Reduces membrane abrasion during installation (extends membrane life by 20%).
• Conical Thrust Cone: Optimizes water flow, reducing pressure drop by 15% vs. flat-end designs.
• Material Options: Standard FRP (lightweight) or optional 316L stainless steel (for extreme corrosion).

Where to Use It?

• Industrial RO Systems: Brackish water desalination (1000PSI models).
• Municipal Water Plants: Large-scale pure water production (8-element side entry).
• Food & Beverage: High-pressure membrane filtration for juice concentration.
• Outdoor Installations: UV-resistant coating ideal for solar-powered RO units.

Membrane Housing specification (4040/8040)

Membrane housing features

• 1. Smooth Inner Surface Finish: The housing is designed with a smooth inner surface finish, facilitating easy loading and unloading of membrane elements for maintenance and replacement.
• 2. End Entry and Side Entry Options: The housing offers both end entry and side entry configurations, providing installation flexibility based on system requirements.
• 3. Variety of Side Port Sizes: Side entry vessels come with different sizes of side port connections, allowing for compatibility with various plumbing setups.
• 4. UV-Resistant Outer Coating: The housing is coated with outer polyurethane paint, enhancing UV resistance and ensuring durability in outdoor or exposed environments.
• 5. Accurate Head Seal Area: The head seal area is precisely formed on the mandrel surface, ensuring a more accurate and secure seal between components.
• 6. Secure Head Seal Installation: The head seal is designed to be captured and prevented from rolling during the installation of the head assembly, ensuring proper sealing.
• 7. Improved Water Flow: The downstream conical shape thrust cone enhances water flow patterns within the housing, optimizing performance, and allowing for the installation of the head assembly at various angles.
• 8. ISO9001:200 Certification: The housing is manufactured according to ISO9001:200 quality standards, ensuring consistent quality and adherence to industry best practices.
• 9. Hydrostatic Testing: Each housing undergoes a 100% hydro test at 1.5 times the operating pressure, ensuring structural integrity and leak-proof performance under operating conditions.

FAQ: 8040 Membrane Housing

End entry vs. side entry-how to choose?

A: End entry (vertical installation) saves floor space; side entry (horizontal) allows easy membrane loading/unloading in tight spaces (e.g., skid-mounted systems).

What's the max elements I can install?

A: 1-4 elements for 4" end port models; 1-8 elements for 8" side port models. Custom configurations (e.g., 6 elements) are available on request.

Is it compatible with all 8040 membranes?

A: Yes! Fits standard 8040 RO membranes (e.g., Dow BW30-8040, Hydranautics ESPA4-8040).

How to ensure leak-proof sealing?

A: Precision-machined head seal area + captured O-ring design prevents rolling during installation. Each housing undergoes a 1.5× pressure hydro test (e.g., 2000PSI model tested at 3000PSI).
