KC and KTC Rotary Piston Pumps can produce the lowest possible pressures from mechanical pumps and are recommended for applications where the operating pressure is below 0.1 Torr. These two stage pumps are extremely rugged and reliable. Because they have no metal-to-metal contact between the pump pistons and cylinder, clearance are filled with oil. Gas ballast operation is possible with single stage pumps. KC and KTC Pumps are air-cooled except the KTC-112 and KTC-225 which are water-cooled. (Optional air cooling systems are available.)

KTC Triplex Pumps are three-piston pumps and have the additional advantage of being vibration-free.
