Products - Steam Engines
Seeing a lucrative market develop for equipment to drive their fans, in the 1870s they introduced their first steam engines. Over the years, both vertical(up to 150HP) and horizontal(up to 250HP) engines were used to drive fans, blowers and electric generators. Only the 20th century designs had letter model names. Technological obsolescence ended that product line in the early 1930s. WW2 briefly brought back the vertical engines. The scarcity of skilled Navy mechanics required the use of relatively simple steam engines. The foundry patterns that were still in storage went back into production and hundreds of Sturtevant engines were built for the famous Liberty ships.
The two types differed in their working pressures, (HS-1) was built for 125lbs, (HS-2) for up to 70lb.
They could be furnished for either high or low pressures, including heating boiler pressures of 15-20 lbs. This made them ideal for driving fans in heating and ventilating systems.
When direct connected to fans, the fly wheel is replaced by a small hand wheel and no governor is used.
They differed only in their oiling arrangements. The VS-7 had a gravity system while the VS-8 used forced lubrication supplied by an oil pump located in the base.
