QV Vacuum Pump Key Features

Quincy QV rotary vane vacuum pumps can consistently provide enough volumetric capacity to meet the needs of the most demanding operations. These pumps are ideal for many applications, particularly in the aerospace and automotive industries. Automakers depend on these pump designs for manufacturing products that involve fluid movements, like transmissions, power steering systems and brakes.

The QV rotary vane vacuum pump series contains 13 different all-purpose models with varying horsepower capable of handling a broad range of demands. Each QV pump is a stand-alone supply system with the flexibility to quickly relocate if needed. The Quincy QV can work as part of a simplex, duplex or triplex package.

Stacked systems and tank mounting options are also available for installations where floor space is limited.

Primary features include:

  • An integrated valve eliminates return air and lubricant into the pump by preventing backflow.
  • A cast-iron, precision-machined rotor with non-metallic vanes promotes minimal wear and extended machine life.
  • A heavy-duty flange adaptor provides permanent motor alignment.
  • The discharge check-valve eliminates reverse flow.

QV 1.5 to 10 Horsepower Vacuum Pump Performance

We engineer the QV series pumps to run continuously throughout their lifetime, similar to the larger, long-lasting QSV pumps. The pump’s core features a module containing heavy-duty industrial bearings for long service life. Control options are available for applications that require on/off or load/no-load operations.

We can package the QV series to accommodate the needs of almost any vacuum system.

Sound levels have become a critical consideration for applications using rotating equipment. QV series vacuum pumps operate quietly to provide an effective option in areas where people work close together.

Quincy vacuum pumps use a high-tech sealant and lubricant to seal the compression chambers and provide cooling within the pumping module. Air entrained with lubricant passes through a multistage separation system to deliver a clean air discharge. The ratio of media-surface-area-to-volume flow is the highest and most efficient in the industry.

Maintenance for Quincy QV 1.5 to 10 Horsepower Vacuum Pumps

Following a routine maintenance schedule is essential for a long product life with minimal downtime. The simple design of the QV series makes them easy to service. We supply fluids and genuine parts to serve all your maintenance needs.

No other components need routine servicing outside of a yearly oil and filter change. We engineer our non-metallic vanes to have at least a 35,000-hours service life. These features add up to a maximized life span between system overhauls.

In addition, our extensive dealer network can provide prompt maintenance and repair services whenever you need them.
