"Well, hello, Mrs. Cleaver, don't you look lovely today." Haskel International keeps up the pressure, not with the blatant insincerity of an unctuous high schooler named Eddie of "Leave It To Beaver" fame, but with its hydraulic and pneumatic high-pressure pumps, gas boosters, chemical injection pumps, and air-pressure amplifiers. It also offers BuTech high-pressure valves and fittings. A wide range of companies -- including those in the automotive, energy, aerospace, and military industries -- use the company's products in applications such as the pressurization, transfer, storage, and control of liquids and gases. Hamilton Sundstrand, a division of United Technologies, acquired Haskel in 2004.
