Sundyne Integrally Geared Pumps in High Pressure Water Applications Sundyne integrally geared pumps are widely used in refineries and petrochemical plants where they typically handle low density, high vapor pressure hydrocarbons. Did you know they’re also used in high-pressure water applications? In the late 1950’s, the Sundstrand Corporation aerospace division developed a sophisticated compact high pressure water injection pump for the Boeing 707 aircraft engine. Sundstrand engineers recognized the opportunity for this new technology in other markets and designed heavy-duty integrally geared pumps and compressors for uses outside of the aerospace industry. |
