Pentair Codeline pressure vessels hold the membrane elements in virtually every SWRO and BWRO plant in the Gulf. When an end closure, permeate port or seal fails, the vessel — and often the train — is out of service. End closure assemblies, permeate port kits, seal and O-ring kits, locking segment sets and adaptors for Codeline 40 and 80 series vessels — DDP from Dubai and Spain. 4-hour response on plant-down enquiries.

Pentair Codeline is the most widely specified membrane pressure vessel brand in RO desalination. Codeline 80 series (8-inch) and 40 series (4-inch) FRP vessels — in pressure ratings from low-pressure BWRO service up to 1,200 psi seawater duty — house the membrane elements in SWRO and BWRO plants across Saudi Arabia, UAE, Qatar, Kuwait, Oman, Bahrain and throughout Africa and Asia. The vessels themselves last decades; the serviceable components do not. End closures, permeate ports, seals and locking hardware are opened at every membrane replacement and are the points where wear, corrosion and handling damage accumulate.
A failed or damaged closure takes the vessel out of service and can hold up an entire train during a membrane change-out. Codeline spares are highly specific — components differ by series, diameter, pressure rating and vessel generation — and local stock in the Gulf and Africa is limited. Meliora sources genuine Codeline replacement components and ships DDP to your plant, with 4-hour response on plant-down enquiries.
Codeline components are matched to the vessel model code on the vessel label — typically stating series, diameter, pressure rating and side/end port configuration. Send the full model code, the vessel pressure rating and a description or photo of the failed component. If the label is unreadable, photos of the closure and port arrangement are usually sufficient for positive identification. Ordering closure components against the wrong vessel generation is the most common and most costly mistake in vessel maintenance — we verify the match before quoting.
Every membrane replacement means opening every vessel in the train. Seals should be replaced at each opening as standard practice, and a stock of spare closures per hundred vessels protects the change-out schedule against handling damage. We quote seal kits and closure spares in train quantities alongside membrane element supply — one RFQ, one DDP shipment covering elements, interconnectors, seals and closures together.
We ship DDP from our Dubai FZCO entity and EU sourcing hub in Almería, Spain to the GCC, North, East, West and Southern Africa, the Maldives, South Asia and beyond.

The vessel model code from the vessel label — covering series, diameter and pressure rating — plus a description or photo of the required component.

Yes. Head seals and port O-rings are single-service components in best practice — replacing them at every opening prevents the leaks and re-openings that extend membrane change-out shutdowns. We quote seal kits in full train quantities for scheduled change-outs.
Yes. We combine membrane elements, interconnectors, seals, closures and adaptors into a single RFQ, one DDP shipment and one USD invoice — so the complete change-out scope arrives together.
We respond to plant-down enquiries with availability and DDP pricing within 4 business hours. Airfreight delivery of in-stock components is typically 5 to 10 business days DDP, with overnight final delivery capability across the GCC from Dubai.
