The UK company provided the original pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform situated in the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite is highly corrosive, Amarinth originally used titanium alloy for all wetted components.

The first involved a full rebuild, test and warranty of the first pump changing all the titanium parts together with impeller, shaft, bearing brackets and mechanical seals. The work needed to be accomplished in simply eight weeks. เพรสเชอร์เกจลม prioritised the ordering of the titanium elements and was able to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the same work on the opposite two backup pumps to be completed on a 24-week schedule.

We are additionally happy with the expansion of our local UAE facility for service and help and which enabled us to efficiently expediate this specific refurbishment, benefiting both ADNOC and the native economic system.”
