Hamworthy Svanehoj has launched a range of combined seawater lift and fire pumps for the offshore market. The new DWS deep-well seawater lifting and fire pumps range in capacity from 700 to 1,700 cu m/hr. The pumps are driven by a dry-mounted electric motor in explosion-proof execution through a pipe stack with transmission shaft and cargo lubricated bearings.

According to the company, the pump head is designed for optimum efficiency using computational fluid dynamics and full-scale tests. Impellers have been trimmed to provide 15% higher head per flow unit, while the semiradial design provides a more stable performance curve at higher capacities.

The pumps also can be used for applications involving chemicals, condensate, LNG, liquefied petroleum gas, onshore CO2 pumping, and offshore and onshore oil storage.
