Gorman-Rupp self priming pumps were recommended for the pumping of
filtered seawater at the Daydream Island Resort in Queensland.
Filtered seawater needed to be pumped to the Living Reef on the North
Side of the Daydream Island Resort at a flow rate of 180m¬≥/hour using a dual
pump arrangement. The use of submersible pumps in this application would have necessitated
the construction of a wet well with lifting apparatus while standard
centrifugal pumps would have required a dry well.
Given the challenges, self priming pumps were considered for the
application because they could be installed relatively inexpensively when
compared with the other options. However, the tropical temperature seawater demanded
a pump made of materials that could resist corrosion in the marine environment.
Gorman-Rupp self priming centrifugal pumps constructed from CD4MCu, a
duplex stainless steel offering greater corrosion resistance than 316 marine
grade stainless steel, was recommended for the application.
Being self priming, and more importantly, a ‘guaranteed’ re-priming
pump, the pump assembly could be mounted high above the seawater, with only a
simple concrete slab needed to mount the pumps. A 100mm pump was used for the resort
Gorman-Rupp self priming centrifugal pumps are available in a broad
range of sizes from 50mm to 250mm, and are constructed in various materials to suit
diverse applications. The pump can pass large solids measuring up to 75mm in diameter,
and features a large inspection cover-plate for operators to gain access to the
pump internals during maintenance.
