This inverted vertical triple expansion pumping engine, built in 1910 by Hathorn, Davey & Co Ltd of Leeds, is representative of the last phase of modern reciprocating steam pumping engines. It is a highly efficient design and was used at Southfields Pumping Station, Newmarket until c1964. It was removed to Kew Bridge in 1978 and later re-erected and returned to steam.
The three Corliss valve cylinders are 12″, 21″ & 30″ bores x 30″ stroke. The two flywheels are 7′ 6″ diameter. It was rated at 110 hp at c30 rpm on steam at 160 psi.
This view is at the cylinder level and shows the layshaft operating the Craig’s Corliss gear. This was with the permission of the site’s operators. The whole engine is seen here – [[2202003]]. This shows how steep the access ladder is and how cramped this platform is.
