Boughton Pumping Station
Hathorn Davey 'Differential' engine at the Boughton Pumping Station of Nottingham City Waterworks. Date of photo unknown.
The Davey 'differential' was a non rotative engine in this case having two cylinders 24" & 44" bore. This engine is almost certainly the one installed over the pilot well at Papplewick during well sinking operations so dates from around 1881. It was removed to Boughton to carry out a similar task. It pumped 1.5 million galls per day from 400 ft and delivered to a triple expansion engine for high lift duty. Another photograph appears in George Watkins' book "The Steam Engine in Industry" Vol.1. This photo was donated by the last Papplewick Deputy Superintendent, Michael Paul.
From Wiki: Hathorn Davey was a British manufacturer of steam engines, based in Leeds. The Sun foundry was established in 1846 and made railway engines and pumping machinery until 1870.
