A quotation of 27th January 1909 from Gwynnes Limited of Newcastle-upon-Tyne refers to the supply of four 18” vertical spindle centrifugal pumps with cross-compound engines complete with shafting and also two Babcock & Wilcox boilers each of 6,000 lbs. evaporative capacity, with suitable donkey feed pump and connections for the sum of £3,000 net delivered free at Wallsend, including the service of a fitter to superintend and assist in the erection and trials on the Tyne. They confirmed the output of 6,000 gallons of water per minute with a maximum head of 28 feet and a mean head of 20.5 feet. This capacity was however, later revised upwards but at the same price, since they realised that the original specification would not be sufficient to supply steam to the two pumping engines, capstans, and salvage pumps if all were working at maximum capacity at the same time.
