CP horizontal radially split multistage barrel pumpCP ISO 13709 / API 610 Type BB5 radially split barrel casing pumps are used in both high-pressure oil production and high-temperature refinery applications.
Sulzer pumps increase recovery rates
Fifteen water injection pumps are optimizing production at Iraq’s largest oil field
Class-leading efficiency and reliability
Following on from initial consultations between the customer and Sulzer oil & gas specialists, the company’s CP pumps were selected for the EOR application. The volute design of the CP range offers improved energy-efficiency over alternative designs: the Sulzer pumps could deliver the required pressure and volume using a 4.6 MW motor running at 3’000 rpm. That would save between 300 and 500 kW of installed power at each pump, reducing the capital cost of the equipment and delivering significant operating cost savings over the lifetime of the installation.
The remote location of the Rumaila field also meant that reliability and straightforward maintenance were a priority. The CP pump offers good solids tolerance, reducing the risk of damage if sand is carried over into the feed water. In addition, the pump casings are axially split, allowing for easy access when maintenance is required. With a long-track record of work with Iraq’s oil and gas industry, Sulzer has specialist local field service teams in the country to support its customers on-site.
Engineered to order
While the CP pump has a standardized and well-proven design, pumps of this size are engineered to meet the customer’s precise operating specifications. For this project, that meant the Sulzer team had to complete an end-to-end design, source, build and test program in line with the customer’s demanding delivery schedule.
As part of the engineering specification, the Sulzer sourcing team had to find a specialist NORSOK-qualified foundry that could produce parts using a particular grade of super duplex stainless steel. The high quality material was central to the design of the pumps and would provide long-term durability in the arduous application.
The fifteen pumps and their drive motors were all assembled on skids and string-tested at Sulzer’s Leeds facility before onward shipment to Iraq. Once in the country, Sulzer field engineers helped the customer install the pumps into three purpose built pumping stations. All 15 were delivered on time in accordance with the customer’s build schedule.
