The UK firm supplied the original pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform situated within the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because เกจวัดแรงดันปั๊มลมpuma is highly corrosive, Amarinth initially used titanium alloy for all wetted parts.
During a routine capital evaluation, ADNOC decided the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are critical to manufacturing and refurbishment had to align exactly with a selected shutdown schedule.
The shutdown schedule would not permit the pumps to be returned to the UK for a full strip, evaluation and refurbishment, so Amarinth used its UAE facility to undertake the work.

The work wanted to be completed in simply eight weeks. Amarinth prioritised the ordering of the titanium components and was in a position to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second challenge undertook the identical work on the other two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having supplied the original pumps to ADNOC we have a wealth of expertise in working with titanium elements. We are additionally pleased with the expansion of our native UAE facility for service and assist and which enabled us to successfully expediate this explicit refurbishment, benefiting each ADNOC and the native economy.”
