Rotary Piston, Rotary Vane and Dry Screw Vacuum Pump



Rotary Piston Vacuum Pump


KT pumps are quiet running vacuum pumps with high pumping capacity at both high and low pressures. The triplex piston design is inherently dynamically balanced and is practically vibration-free. Even in dirty applications, the KT enjoys unequalled durability, as there is no metal-to-metal contact between the pump piston and the

cylinder; clearances are filled with oil. All KT models include an integral, positive pressure lubrication system to insure reliable lubrication at all pressure levels. 

KT pumps are water-cooled; however, optional air-cooling systems are available on several sizes. Adjustable gas ballast valves are included as standard equipment for handling water and other vapor loads. LP series KT pumps incorporate all the features of the standard KT pumps, in addition to an integral oil mist eliminator and a compact, low-profile design.


Typical Applications:

Vacuum Packaging

Vacuum Furnaces

KT-1350VFP   778/1322         40/30


Dry Screw Vacuum Pump


Dry screw vacuum pumps operate without oil or water in the pumping chamber, and

with their straight-through design, the KDP and SDV can handle both condensable vapors and some solids without leaving residue.

There is no metal-to-metal contact inside the pumping chamber, so wear is greatly reduced.

Kinney dry screw pumps are water-cooled, but self-contained air-cooled coolant recirculation systems are available.


Typical Applications:

Chemical and Pharmaceutical Processing

Solvent Recovery



Dry Etching

Rotary Vane Vacuum Pump


KVO/KVOH rotary vane vacuum pumps provide an economical source of vacuum for those applications where the process is relatively clean or filtered. Gas ballast valves for vapor handling applications are included as standard equipment.

of components for your specific needs.


Booster/Rotary Piston Vacuum Pumping Systems


Kinney Booster/Rotary Piston vacuum pumping systems pump high volumes at very low pressures. A high-capacity dry rotary lobe vacuum booster is matched to a smaller rotary piston vacuum pump. For continuous operation below 1 Torr (1.3 mbar a), the vacuum booster can increase the pumping speed of the vacuum pump by a factor of 10 or more, resulting in a higher capacity system with economy of scale. For operation at higher pressure and for faster evacuations, the booster may be approximately twice the capacity of the piston pump. Conventional systems with either direct driven or V-belt driven boosters and low-profile systems with close-coupled boosters are available.


Performance ranges from 200-2700 CFM (340-4590 m3/h) with ultimate vacuum levels as low as 0.2 microns. Custom engineered system solutions to 10,000 CFM (17000 m3/h) are also available. Our application engineers can help you make the best selection for your specific needs.


Typical Applications:

Transformer Oil Drying

Vacuum Furnaces
