Pressure Atomizing Oil Burner Equipment and Systems – Oil Pumps
Single stage rotary gear pump, with light weight die cast body, two hole flange and barrel mount for close, direct motor coupling; with internal pressure regulating and cut-off valves, inlet oil strainer and oil bypass, it would set a new standard for fuel oil pump assemblies, part of a 4th wave in engineering design, characterized by compacted and functionally integrated engineering, Fuelstat, EN, Tuthill Pump Co. Chicago, Circa 1937.
Technical Significance:
From the vantage point of the early 21st century, the evolution of oil fired, automatic home heating equipment would be seen as generally advancing in four broad waves, each of which would take place over a considerable period of time, each producing many variations of the genre:
1. Vaporizing, non-motorized and non-electrified, technology [see Group 11.01 artifacts, no. 11.01-1]
2. Elemental, motorized, platform mounted technology with peripheral piping and valving components [see Group 12.01, artifact no 12.01-1, and pump assembly 12.06-1]
3. Compacted motorized technology with inherent, peripheral component parts engineered into the pump assembly [see pump assembly Group 12.06, artifact, and 12.06-2]
4. Functionally integrated, motorized technology, beyond being compacted, a number of functions would be smoothly integrated into a single pump assembly, including piping and valving [see Group 12.01, artifact 12.01-2 and pump assembly 12.06-2]
This pump assembly stands as an example of 4th wave of fuel oil pump assemblies, compact and functionally integrated in light weight die cast body.
Industrial Significance:
Tuthill would be widely acknowledged in the industry as an early innovator in the field, providing many of the engineering ideas, principles, products and breakthroughs which the industry would build on – see for example ID#271, 272, 273.
