Apollo Gößnitz GmbH is pleased to announce the successful delivery of two special barrel pumps of the BB5 series according to API610 12 Edition. These machines will be used offshore in the Norwegian oil sector.
Apollo uses the latest calculation programs in the design of the machines to be able to manufacture these multi-stage high-pressure pumps according to the latest technology. These giants are designed to handle flow rates of up to 1000m³/h at maximum operating pressures of up to 300 bar. The resulting power requirement is up to 6MW.
One of the main challenges of this project was the high demands on the material quality of the pressurized components. The pumped medium, warm process/salt water with a certain amount of solids, required special emergency running properties and high wear resistance.
In addition to this application's typical NORSOK requirements, special surface hardening processes were applied to individual components. An additional challenge was the casting of the components, weighing up to 10 tonnes, by specially certified foundries.
A further technical innovation to meet the special NPSH performance requirements of the pumps was the double-suction impeller with a diffuser.
After completing the units in Gößnitz, we successfully tested both machine units, including frequency converters and transformers, on our test field in the presence of the customer.
The pump units, each weighing 25 tonnes, will now be able to operate reliably in the Norwegian sector of the North Sea. With these two pump units, we are once again demonstrating our expertise and many years of experience, and we are proud to be able to support our customers with custom solutions as a reliable partner.
