Oil-Sealed Rotary Piston Vacuum Pumps
Rotary Piston Vacuum Solutions for Demanding Applications
Air Centers of Florida offers Kinney rotary piston oil-sealed vacuum pumps, a legacy product line originally developed under the Tuthill name and widely recognized for ruggedness, reliability, and long service life in demanding applications. Kinney rotary piston vacuum pumps are engineered to deliver high pumping capacity at low pressures while handling especially dirty or harsh processes. Models including the KT, KC, KTC, KD, and KDH feature no metal-to-metal contact between the piston and cylinder, reducing wear and ensuring dependable long-term operation. Oil-filled clearances provide effective sealing across a wide pressure range, with configuration options such as duplex or triplex piston designs and air- or water-cooled systems to meet specific operating requirements. Kinney oil-sealed vacuum pumps are widely used in research laboratories, engineering environments, and industrial production facilities, where their compact design, durability, and ability to operate continuously make them a trusted standard—backed by a 30-month manufacturer warranty.
Types of Rotary Piston Vacuum Pumps
KC Rotary Piston Vacuum Pumps
The Kinney KC Series rotary piston oil-sealed vacuum pumps are air-cooled, two-stage systems built for reliable industrial performance. With no metal-to-metal contact and standard gas ballast valves, they handle condensable vapors while minimizing wear. Backed by a 30-month manufacturer warranty.
Available Models: KC5, KC8, KC15
KT Rotary Piston Vacuum Pumps
The Kinney KT Series rotary piston oil-sealed pumps are single-stage, water-cooled units designed for demanding applications. An integral lubrication system and gas ballast valves ensure stable performance across varying pressure levels.
Available Models: KT150C, KT300D, KT500D, KT850D
KD & KDH Rotary Piston Vacuum Pumps
The Kinney KD and KDH Series oil-sealed rotary piston pumps deliver dependable industrial vacuum performance. KD models are air-cooled, while KDH models provide water cooling for higher thermal demands.
Available Models: KD30, KD50, KDH130, KDH150
KTC Rotary Piston Vacuum Pumps
The Kinney KTC Series features a triplex piston design for smooth, low-vibration operation. Air-cooled models are standard, with water-cooled configurations available for higher-demand environments.
Available Models: KTC21, KTC60, KTC112
