John Crane is the world’s leading mechanical seal manufacturer, and its seals run in pumps, mixers and rotating equipment across every process industry. A failed seal stops the pump — and the process. Type 21 and Type 1 elastomer bellows seals, 5600 series cartridge seals, API 682 arrangements, replacement seal faces and elastomer kits — sourced from Dubai and Spain, DDP worldwide. 48-hour response on seal RFQs.

Mechanical seal failure is the single most common cause of unplanned pump downtime in process plants. John Crane seals are the global reference — from the Type 21 and Type 1 elastomer bellows seals fitted to millions of general-service pumps, to engineered cartridge seals and API 682 arrangements on refinery and petrochemical duties. When a seal fails, the pump is down until the correct replacement — matching seal type, size, face materials and elastomers to the service — is fitted.
Outside Western Europe and North America, obtaining the correct John Crane seal quickly is a recurring procurement problem: local stock is thin, engineered seals are built to order, and misidentified seals waste weeks. Meliora sources John Crane seals and spares through established supply channels from Dubai and Spain, and ships DDP to plants across the GCC, Africa, Central Asia and South Asia.
The fastest route is the John Crane part or assembly number from the seal or pump documentation. Without it, send the pump make and model, shaft or sleeve diameter at the seal, the sealed fluid with temperature and pressure, and photographs of the failed seal. Face material and elastomer selection must match the service chemistry — we confirm the specification before quoting so the replacement seals correctly the first time.
A seal that fails repeatedly is telling you something about the pump or the process — dry running, misalignment, vibration or the wrong face/elastomer combination for the fluid. When you describe the failure mode with your RFQ, we can flag where an upgraded face material or a different arrangement would outlast a like-for-like replacement, and quote both options.
We ship DDP from our Dubai FZCO entity and EU sourcing hub in Almería, Spain to the GCC, North, East, West and Southern Africa, Central Asia, South Asia and beyond. Airfreight for pump-down urgency.
Seal failure stopping a pump? Send the seal or pump details via the form or WhatsApp. DDP quote within 48 hours; 4-hour response on plant-down emergencies.
Pump make and model, shaft or sleeve diameter at the seal location, the sealed fluid with its temperature and pressure, and photographs of the failed seal. That is sufficient to identify the seal type, size and correct face and elastomer combination for the service.
Yes. We source single and dual cartridge arrangements including API 682 configurations for hydrocarbon duties, with the conformance and material documentation refinery maintenance systems require. State the API plan and arrangement with your RFQ.
Yes. Replacement faces — carbon, silicon carbide, tungsten carbide — and elastomer kits are available for repairable seal types, which is often the economical path on larger seals. We quote both the repair kit and the complete seal so you can compare.
Standard RFQs receive a DDP quote within 48 hours; pump-down emergencies via WhatsApp receive a response within 4 business hours. In-stock seals deliver by airfreight typically within 5 to 10 business days DDP. Engineered and built-to-order seals carry factory lead times which we confirm before you commit.
