Reliable & Durable Rotary Vane Vacuum Pumps

Rotary Vane Vacuum Pumps by Kinney

Kinney rotary vane vacuum pumps are widely recognized for their versatility, high-end vacuum capability, and proven performance across a broad range of industrial applications. These rotary vane pumps are designed to provide stable vacuum output, low noise levels, and minimal vibration, contributing to safer, quieter, and more efficient operating environments.

Each rotary vane vacuum pump is oil-lubricated to improve sealing, tighten internal clearances, and maximize pumping efficiency. The oil also plays a critical role in optimized oil-water separation and enhances tolerance to high water vapor loads, making Kinney rotary vane vacuum pumps well suited for demanding processes where moisture or condensable vapors are present. With proper maintenance, this design contributes to an extended service life and reduced total cost of ownership.

Kinney rotary vane vacuum pumps are built to address both rough and medium vacuum requirements, offering a broad range of pumping speeds to match specific system demands. Their rugged construction makes them suitable for continuous-duty operation, even in applications with fluctuating process conditions or varying levels of carry-over.

Key advantages of Kinney rotary vane vacuum pumps include:

• Oil-assisted filtration that protects internal components while removing contaminants from the process stream
• Broad vacuum range coverage for industrial, manufacturing, and laboratory applications
• High reliability under continuous-duty conditions
• The ability to continue operating, even in adverse scenarios such as vane damage, until scheduled maintenance can be performed

By combining robust mechanical design with efficient oil-lubricated operation, Kinney rotary vane vacuum pumps provide dependable performance and the flexibility needed to support today’s most demanding vacuum processes.

Industries/Applications

Oil-sealed rotary vane vacuum pumps are simple, quiet, and efficient, and offer a very attractive $/CFM ratio when compared to other vacuum technologies. Rotary vane vacuum pumps are used in a wide variety of end markets and applications in which vacuum is used to pull a given product. They include:

• Transformer drying that is used for oil purification. Vacuum is applied to pull impurities and water from oil so that it can be reused.
  
  
• Thermoforming or injection molding where plastic is formed into the desired shape by heating and pulling vacuum on a mold. This technology allows smooth uniform product free of air bubbles and impurities. The plastic is then cooled, holds the shape, and is ready for use. Molded plastics are used in the automotive (dashboards) and food and beverage (packaging) industries, among others.
  
  
• Plastics extrusion which uses heated plastic pellets to form a desired shape, which is then formed and cooled through an extruder. Rotary vane pumps provide the vacuum needed to allow the product to hold its shape during the process. The technology is used to produce products such as plastic pipes for the construction industry.
  
  
• Food packaging where rotary vane pumps are used to remove air from products while they are being packaged and sealed. This allows meat and other food products to remain fresh for a longer amount of time.
  
  
• Freeze drying is another vacuum application used in food packaging. Rotary vane pumps are used here to pull moisture out of various food products such as freeze dried fruits and vegetables before they are packaged.
  
  
• Central vacuum systems that provide vacuum to numerous inlets installed in a building’s walls. Such systems can be used for vacuum cleaning. When installed in hospitals, they support various medical vacuum applications including the operation of surgical beds, the dosing of anesthesia and the aspiration of liquids, gasses and residues.
