History

For more than 140 years Stanadyne, and its predecessor companies, has thrived on creating one-of-a-kind solutions to the world’s most vexing problems in diesel and gasoline fuel systems. The company dates back to 1876 as the Hartford Machine Screw Company and was founded on its revolutionary innovation, the automatic screw machine. In ensuing years, Hartford Machine Screw Company markedly improved the efficiency of manufacturing, helping to fuel the industrialization of America.

In 1900 the company changed its name to the Standard Screw Company, eventually becoming a leading supplier of precision metal components. From 1914 to 1945, Standard Screw handled contracts from the United States government to help produce aircraft parts and war materials.

In the post-World War II era, the company entered a new age of innovation. Vernon D. Roosa joined with his design concept for a diesel fuel injection pump that was smaller, lighter and more technically advanced than the fuel pumps available at the time. The rotary pump, as it became known, greatly improved the efficiency, power, and practicality of diesel engines with new fuel distribution technology, allowing diesel engines to become the primary choice for heavy equipment and machinery.

As the rotary pump design evolved, so did its applications, breaking into the automotive and transportation market, allowing vehicle manufacturers to develop new, more efficient engines. Diesel engine use continued to rise and the Standard Screw Company adapted, meeting the challenges with new pumps and fuel systems, each time introducing innovative changes that increased efficiency and performance. Other notable inventions of this time period include; the DB Model rotary pump (1952) and the Pencil Nozzle® fuel injector (1963).

When Standard Screw Company became Stanadyne in 1970, the company ushered in a new wave of technologies, including fuel filters and additives. At the time, Stanadyne diesel fuel pumps offered the most fuel-efficient design and the company experienced rapid growth during the 1973 oil crisis.

In the following years, the company expanded its portfolio to include electronic governing diesel rotary pumps, diesel common rail pumps and direct injection fuel pumps for gasoline engines. In the early 2000s, Stanadyne introduced the world’s first 200 bar gasoline direct injection pump to the automotive market. It was quickly followed by another gasoline direct injection pump for the racing industry. With rapid innovation in gasoline and diesel fuel systems, the company was at a crossroads. In 2014, the company sold the fuel filters and additives business to focus solely on fuel pumps and injectors.

Today, the company is reimagining its product portfolio and providing tailored solutions for its customers. As the company embraces the future of fuel, it continues to innovate and develop new technology to improve the efficiency, power and performance of fuel systems.
