Amarinth has refurbished sodium hypochlorite dosing pumps for ADNOC on schedule using its facility in the United Arab Emirates to meet strict shutdown deadlines.

The UK firm 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.
During a routine capital assessment, ADNOC decided the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are crucial to production and refurbishment had to align precisely with a selected shutdown schedule.
The shutdown schedule wouldn’t enable 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.
Amarinth’s UAE facility was able to complete the strip and assessment report inside five working days and suggest two refurbishment initiatives. The first concerned a full rebuild, take a look at and warranty of the first pump replacing all of the titanium elements including impeller, shaft, bearing brackets and mechanical seals. The work wanted to be completed in simply eight weeks. Amarinth prioritised the ordering of the titanium components and was able to have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the same work on the other two backup pumps to be completed on a 24-week schedule.
เกจวัดความดันpressuregauge , managing director of Amarinth, stated: “Having supplied the original pumps to ADNOC we now have a wealth of experience in working with titanium elements. We are additionally pleased with the growth of our local UAE facility for service and support and which enabled us to efficiently expediate this particular refurbishment, benefiting both ADNOC and the native economic system.”
