Amarinth Secures Major Order from ENPPI for 27 API 685 Magnetic Drive Pumps

The MERAM initiative is one of ADNOC’s gas processing infrastructure developments, engineered to increase ethane extraction and deliver feedstock to downstream facilities. Following the award of the EPC contract to ENPPI, ADNOC recommended Amarinth to the Egyptian engineering contractor for the magnetic drive pump package, according to Amarinth. Amarinth already has more than 450 pumps installed throughout ADNOC facilities.

The contract encompasses 27 API 685 magnetic drive pumps, specified in a combination of horizontal and vertical configurations to satisfy diverse duty points and footprint requirements across the plant. The API 685 magnetic drive design was selected over conventional mechanically sealed API 610 pumps as it features a hermetically sealed, stationary containment shell, with torque transmitted contact-free from the drive motor through external and internal permanent magnets. This construction is designed to prevent fugitive emissions and product loss under aggressive process conditions, and can reduce maintenance demands and overall equipment footprint.

Nitrogen Purge System

A technical demand of the MERAM project arose during Hazard and Operability (HAZOP) safety reviews regarding the pump drain line system. In standard installations, high back pressure within the drain can impede effective liquid drainage and vapour clearance during shutdown, flushing, or maintenance cycles. Any accumulation of trapped, volatile hydrocarbons presents potential safety and operational risks.

To address this issue, Amarinth engineered an integrated nitrogen purge system. This design counteracts downstream drain line back pressure by delivering a controlled, positive-pressure nitrogen sweep through the casing and containment shell. Volatile fluids and trapped vapours are evacuated into the disposal system to allow operational isolation during inspection and maintenance without venting hydrocarbons into the atmosphere.

To align with ENPPI’s on-site construction and installation schedule, this 27-pump contract has been structured into three phased deliveries and manufacture is now underway, with delivery of the first batch scheduled for autumn 2026.

Oliver Brigginshaw, Managing Director of Amarinth, commented: “We are delighted to receive this significant order from ENPPI for ADNOC’s MERAM Phase 2 project. ADNOC’s insistence on working with Amarinth is a testament to the trust they place in our engineering expertise and our proven ability to deliver complex projects on time. This contract also underlines the technical innovation of our engineering team in designing a unique nitrogen purge solution that directly answers the project’s HAZOP and back-pressure challenges. Combined with our agile supply chain model, which consistently achieves 98% on-time delivery, we look forward to delivering the first batch this autumn and providing seamless support throughout the installation phase.”
