เกจวัดแรงดัน250bar has refurbished sodium hypochlorite dosing pumps for ADNOC on schedule using its facility within the United Arab Emirates to fulfill strict shutdown deadlines.

The UK firm equipped the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform located in the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite 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 crucial to production and refurbishment needed to align exactly with a specific shutdown schedule.
The shutdown schedule wouldn’t 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.
Amarinth’s UAE facility was able to full the strip and assessment report inside five working days and propose two refurbishment initiatives. The first involved a full rebuild, test and warranty of the primary pump replacing all of the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work needed to be completed in simply eight weeks. Amarinth prioritised the ordering of the titanium components and was able 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’ve a wealth of expertise in working with titanium elements. We are also pleased with the growth of our native UAE facility for service and support and which enabled us to successfully expediate this particular refurbishment, benefiting both ADNOC and the local economic system.”
