The King Street Wharf precinct, which is the area bound by Lime, Shelly & King Streets Sydney houses a range of commercial offices, Highrise hotel and several restaurants of various cultures. In preparation of the Bicentennial Celebration, the NSW embarked on a huge redevelopment of Darling Harbour which included the King Street Wharf (KSW). Work begun on this area in the mid1990s and was completed in 2000. Like many harbour front commercial properties, the sea water is used as the means of Heat Rejection. Pumps were installed in numerous basement plant rooms that serviced the mechanical requirements of the buildings within the precinct.
The original pumps were designed for a 102l/sec flow rate and 250kpa operating pressure. They had cast iron volute casings, backplate and impellers which were pre-heated and applied with Easyglide 954 coatings. This was deemed to be suitable solution at the time and had been applied extensively on valves and pumps on sea water applications and indeed was the preferred product choice of several pump companies when a cost effective solution was required.
