About Seller: Harwood Engineering Company has been involved in the research, development, and production of pressure components and systems since 1947. Our focus is on containing, generating, piping, valving, controlling, and measuring flow and pressure at high levels in both liquids and gases. Initially, our commercial equipment offered pressure capabilities up to 200,000 psi, making us the exclusive providers of equipment exceeding 45,000 psi in the United States. Over the years, Harwood has pioneered the "Controlled Clearance" principle, setting the standard for primary pressure standards globally, reaching levels as high as 30 kbar. Presently, we are constructing primary force standards using a modified version of this principle. For half a century, we have manufactured equipment capable of producing pure isostatic pressures up to 30 Kilobar (430,000 psi) at various temperatures, as well as presses for quasihydrostatic pressures up to 10,000 tons. These pressures are essential for applications such as diamond manufacturing and fundamental research in physics, geophysics, and geochemistry. Given the specialized nature of our market, we do not engage in extensive "agency" style marketing. Instead, our focus is on customized solutions tailored to the specific requirements of each client, necessitating direct and personalized interactions. Those interested in high-pressure activities will find ample recognition of our contributions in publications within the field, including our own articles.
