SOUTHWORTH ENGINES LARGE DOUBLE ACTING

STEAM BOILER FEED PUMP

Originally supplied factory built by Peter Southworth at Southworth Engines

This pump has been designed for full size steam boats and similar applications.

This pump has a Cast Iron Steam Cylinder (ideal for superheated steam) and a Gunmetal Water Cylinder. The pump had a mechanical lubricator fitted, plus a displacement lubricator just in case the main oil feed fails (which is very unlikely - but it looks good).

Alos the pump has an exhaust valve fitted to allow for smmother running & prevent high speed runaway iw the water supply runs out.

This is a beautiful steam boiler feed pump.

6 inch "Southworth" Live Steam Boiler Feed Pump - USED

Made from "Southworth Engines" Gunmetal Castings & Steel. The pump runs very well and in common with all the range of "Southworth Engines" pumps, it moves a good volume of water for its size. Engineering standard is OK and the pump should give years of use. 1/4" x 40tpi unions throughout for 5/32" pipe.

This is a Large "Southworh" Steam Boiler Feed pump. Built to a very high standard by Don English of "Jubilee Fittings".

It runs beautifully - really well - please watch the video. The pump is shown unpainted as can be seen in the photograph.
