Tuthill Kinney KTC112 High Vacuum Pump 107 CFM 7.5 HP Baldor Motor 0.2 Micron

Tuthill Kinney KTC112 High Vacuum Pump 107 CFM 7.5 HP Baldor Motor 0.2 Micron

The Tuthill Kinney KTC112 is a large-frame, oil-sealed rotary piston high vacuum pump rated at 107 CFM displacement. Driven by a Baldor 7.5 HP three-phase industrial motor, it is built for sustained high-vacuum applications demanding deep ultimate pressures — down to 0.2 microns (Torr). The unit is mounted on a steel skid with anti-vibration isolators and includes an integral American Industrial Heat Transfer shell-and-tube heat exchanger, exhaust muffler, gas ballast system, and a United Electric Controls pressure switch.

Applications

The Kinney KTC series (now produced under the Tuthill Vacuum Systems brand) are oil-sealed rotary piston pumps that have been a workhorse of industrial and scientific high-vacuum applications for decades. The KTC112, with its 107 CFM displacement and 0.2-micron ultimate pressure, is well-suited for applications that demand both high throughput and deep vacuum levels — including vacuum furnaces, vacuum coating and physical vapor deposition (PVD) systems, freeze-drying (lyophilization), semiconductor processing, vacuum impregnation, degassing, and large-chamber evacuation in research and industrial settings. The water-cooled design via the shell-and-tube heat exchanger allows continuous-duty operation in demanding production environments. Gas ballast capability helps handle process streams containing condensable vapors. These pumps are commonly used as the primary roughing and holding pump in multi-stage vacuum systems, often paired with a Roots blower (booster pump) to extend the operating range. The KTC112 is a large-capacity unit that would typically be found in facilities such as metal treating, aerospace component processing, electronics manufacturing, or university and national laboratory vacuum systems.
