Rotary Piston Vacuum Pumps

Rotary Piston Vacuum Pumps - Piston Vacuum Pump with Gear Reducer and motorGasho is proud to offer the Kinney® line of rotary piston vacuum pumps from Tuthill Vacuum & Blower Systems. This line of oil-sealed piston pumps covers a broad range of sizes in both single stage and compound pump design. The design of these rotary piston vacuum pumps give them low blank off, high pumping speeds at low pressures and great durability.

Rotary Piston Vacuum Pump Features

KT Series Vacuum Pumps

The KT Series of rotary piston vacuum pumps are designed to provide unequalled durability in all types of applications, including dirty applications. Installation is simple, with no special preparation required.

  • Full Pumping Speed Down to 1 Torr
  • Operate Continuously at any Pressure up to 100 Torr
  • Ultimate Pressure 10 Microns (McLeod Gauge)
  • Quiet, Vibration-Free Operation
  • No Metal-to-Metal Contact in Pumping Chamber
  • Adjustable Gas Ballast Permits Handling of Condensable Vapors

KC Series Vacuum Pumps

The KC Series of two-stage vacuum pumps are designed to achieve lower pressures than can be reached with single-stage pumps. Features include unsurpassed durability, even when used in dirty application environments.

  • Pumping Speed at Pressures Below 10 Microns. Lower than Attainable with Single-Stage Pumps
  • Flows from 5 – 15 CFM (8 – 25.5 m3/h)
  • Ultimate Pressure: .2 Microns (McLeod Gauge)
  • Can Operate at Any Pressure up to Atmosphere
  • Adjustable Gas Ballast Permits Handling of Condensable Vapors
  • No Metal-to-Metal Contact in Pumping Chamber
  • Air-Cooled

KTC Series Vacuum Pumps

The KTC Series of two-stage high vacuum pumps incorporates the “triplex” design, which includes a single shaft and three sets of cams and pistons, each set larger than the other. Pumps in this series maintain lower pressures than are attainable with single-stage pumps.

  • Triplex Piston Design for Quiet, Vibration-Free Operation
  • High Pumping Speed at Pressure Below 10 Microns, Lower than Attainable with Single-Stage Pumps
  • Ultimate Pressure: .2 Microns (McLeod Gauge)
  • Can Operate at Any Pressure up to Atmosphere
  • Adjustable Gas Ballast Permits Handling of Condensable Vapors
  • No Metal-to-Metal Contact in Pumping Chambers
  • Unequalled Durability, Even in Dirty Applications

KD and KDH Series Vacuum Pumps

The KD and KDH Series are single stage vacuum pumps featuring a duplex design. A controllable gas ballast permits handling of condensable vapors and to minimize oil changes due to vapor contamination of the sealing oil.

  • Full pumping speed down to 1 Torr
  • Ultimate Pressure: 0.010 Torrv
  • Can Operate at Any Pressure up to Atmosphere
  • Adjustable Gas Ballast Permits Handling of Condensable Vapors
  • No Metal-to-Metal Contact in Pumping Chamber
  • KD pumps are air cooled; KDH pumps need water cooling for most applications
