Some of you may already know but this Sunday & Monday we are running 3 Lancashire boilers at The Claymills Victorian Pumping Station. This marks the end of a 2.5 year project to return number 1 boiler to steam.
A little history for those who don’t know what I’m on about -
The main pumping plant at Claymills consists of four Woolf compound, rotative, beam pumping engines. These are arranged in mirror image pairs, in two separate engine houses, with a central boiler house and chimney. The engines were built in 1885 by Gimson and Company of Leicester.
The engines were normally run in pairs, never all together, although a third engine was occasionally employed during times of heavy load. These operated at about 10 rpm and two engines had a combined pumping rate of 5.5 million gallons per day. Each engine house contains a single cylinder horizontal air compressing engine, for charging the air vessels (anti surge vessels) on the pump discharge mains. At a later date, horizontal single cylinder barring engines were added (one for each pair of engines).
Steam was supplied at 80 psi, by a range of five Lancashire boilers. Two boilers were steamed with a third on hot standby & one undergoing maintenance with another cold but in operational condition. Alternated every 8 weeks. The originals were replaced in 1937 by the current five. These are fitted with Green's economisers and Meldrum's mechanical stokers. There is one horizontal single cylinder, rotative boiler feed pump by Buxton and Thornley of Burton upon Trent and a vertical by Halls. The boilers also supplied steam to over thirty auxiliary engines. Most of these survive on, and off, the site. Three of these are housed in a more modern block behind the engine house. The best are the pair in the dynamo house. These are a horizontal single cylinder engine, by Buxton and Thornley, dating from 1889, and an inverted vertical duplex engine, built at Claymills circa 1906.
We believe this will be a preservation first & will only be done for a short time while we have 3 boilers in ticket.
If you’d like to see 3 Lancashire boilers generating steam to run the entire site - around 35 working steam engines! We’d love to welcome you on the 3rd & 4th of May 2026 10am - 5pm
