Hamworth first introduced a series of new offshore pumps
To meet the needs of the marine market, Hammworths first developed a new series of pumps that consist of a seawater lift pump and a fire pump. Newly launched deep sea lift pumps and fire pumps range from 700 cubic meters per hour to 1,700 cubic meters per hour and head pressures up to 180 bar. The pump is driven by a dry motor mounted on an explosion-proof actuator with a drive Shaft and a lubrication shaft. These pumps not only enrich the type of Hamworth pump, but also have been put into applications such as seawater lifting and fire fighting. Lars Fischer, Director of Marine Sales at Hammworth, said: "With our strong focus on the offshore industry, it has been our overall goal to develop a range of seawater lift pumps and fire pumps that fully meet API 610 and NFPA -20 and ensures long-term repair, reliable and efficient operation. "The company uses a wealth of design experience, through computational fluid dynamics and comprehensive testing, to achieve optimum pump head lift efficiency. The modified impellers increase the head lift per flow unit by more than 15%, while the semi-radiant design provides a more stable performance curve based on higher performance. After finite element analysis, the spacing between molds was chosen as the maximum stiffness, resulting in a reduction of 30% in the area of ​​gravity across the new area compared to similar structural elements. Designers also give considerable attention to the performance of the bearing. Installing a conical thrust bearing on the top of the drive shaft minimizes vibration. In addition, thrust bearing units are designed for oil circulation in order to comply with the requirements of the American Petroleum Institute (API), which also extends their expected service life. The distance between the drive bearings is fully in accordance with the API 610 standard, which also ensures that the pump will operate stably under all operating conditions. According to the different needs of customers, the pump in the design and production, either with labyrinth seals can also be equipped with mechanical seals. The mechanical seal is cartridge and, as an option, it can be delivered exactly as API682 requires. For the installation of seawater lift pumps and fire pumps in caissons, Hamworth offers its patented inflatable intermediate support system. The purpose of this support system was developed to ensure that the pump is properly installed and operated in a caisson. Mr. Fischer said the new DWS 'pumps are available in a wide range of materials, such as AISI 316L stainless steel, biphasic or super duplex. Depending on the selection requirements, the delivered pump can be equipped with filters, current protection and anti-fouling systems. He also said that the initial development of this new series of pumps was intended for seawater upgrading and firefighting but later it was found that these new pumps were also naturally applied to processes involving chemicals, condensates, liquefied natural gas and liquefied petroleum gas in. Other potential areas of application include pumping of CO2, as well as oil storage offshore and on land.
