QV Vacuum Pump Key Features

Quincy QV rotary vane vacuum pumps have a simple yet effective principle of operation. This makes them an excellent choice for customers interested in reliable vacuum without overly sophisticated mechanics or control systems. The QV rotary vane series contains 6 different all-purpose models with varying horsepower capable of handling a broad range of demands.

These versatile pumps are used in many applications. Used often as point-of-use pumps for plastics thermoforming, food packaging, woodworking hold-down, and more. Quincy QV Pumps can also be combined into systems to provide greater flow, redundancy, and a more “plug-and-play” solution.

Primary features include:

  • An integrated non-return valve helps prevent backflow.
  • A cast-iron, precision-machined rotor with non-metallic vanes promotes minimal wear and extended machine life.
  • A heavy-duty flange-mounted motor ensures proper alignment with no belts
  • Oil return mechanisms allowing for optimum ultimate vacuum
  • Oil cooling circuits using only air. No water requirements.

QV Pump Performance

Quincy QV rotary vane vacuum pumps have relatively flat performance curves.  This ensures they provide consistent volumetric capacity to meet the needs of the most demanding operations.

The pitch of the vanes, size of the separation chamber, and sealing of the surfaces have all been optimized to ensure stable temperatures throughout the vacuum range.  This allows the pumps to be operated continuously with no pressure limitations.

Maintenane for QV Vacuum Pumps

The mechanical simplicity of the rotary vane pump means it’s a great technology for those maintenance DIYers. Routine oil changes, including oil filter and oil separator elements, will ensure product longevity and minimal downtime. The non-metallic vanes and other seals have been designed to operate in the harshest conditions. Consider extending routine maintenance intervals by using full synthetic vacuum vane oils.
