Professionally Refurbished Vacuum Pumps

Vacuum pumps are critical for creating controlled, low-pressure environments across diverse applications. Different vacuum pump types include dry pumps for sensitive applications and oil pump models with high tolerance for moisture and particulates.

Our used vacuum pumps for sale may include:

• Rotary vane pumps: These rough vacuum pumps feature vanes that rotate inside a housing, sweeping gas from the inlet. They are commonly used in labs for rotary evaporators, freeze dryers, mass spectrometry and backing turbomolecular pumps. 

• Diaphragm pumps: This dry pump configuration is similar to a lung. A flexible diaphragm moves up and down, pulling gas in and out. This makes it ideal for sensitive applications that handle corrosive, viscous or solid-laden fluids. 

• Rotary piston pumps: This type of pump is a robust, oil-sealed, positive-displacement mechanism that creates a vacuum by trapping and compressing gas with a rotating piston inside a cylinder. 

• Turbomolecular pumps: These turbo pumps use high-speed rotating blades that impart momentum to gas molecules, accelerating them toward the exhaust. They provide a high, clean vacuum and are widely used in analytical instruments, semiconductor manufacturing and physics research.

• Diffusion pumps: This pump design uses jets of heated oil vapor to sweep gas molecules toward the roughing pump connection. It is used for large-scale, high-vacuum applications, thin film deposition and industrial furnaces.

• Ion pumps: These pumps ionize gas molecules and trap them on reactive metal surfaces. They achieve extremely low, clean pressures and are used in ultra-high vacuum (UHV) systems, surface science and particle accelerators.

• Cryopumps: These ultra-high-vacuum pumps use extremely cold surfaces to condense and freeze gas molecules, removing them from the vacuum chamber. They achieve a high vacuum quickly and are commonly used in semiconductor manufacturing, space simulation chambers and research.

Controllers and Monitoring Systems

Accurate vacuum control ensures your process is reliable, safe and efficient, enabling high-quality results run after run. Controllers continuously monitor the pressure in the vacuum chamber and provide immediate feedback to the system. Features often include programmable set points, real-time pressure display and alarm functions.

We offer integrated solutions for single-stage and multistage vacuum systems to ensure seamless compatibility. Our experts can help you select the optimal controller for precise vacuum regulation, from rough vacuum to ultra-high vacuum environments.

Used control and monitoring equipment may include:

• Digital vacuum controllers: Stand-alone and benchtop models feature clear digital displays for precise pressure readings. They connect to and manage various types of vacuum gauges, with programmable setpoints and proportional integral derivative (PID) control to ensure stability.

• Process controllers: These sophisticated systems use programmable logic controllers (PLCs) to manage the vacuum and other interrelated process parameters. They typically feature graphical user interfaces (GUIs), extensive data archiving, remote monitoring and network integration.

Compatible Vacuum Pump Oils and Lubricants

Our integrated equipment solutions include critical consumables that ensure the long-term health and performance of your vacuum system. We supply a range of high-quality vacuum pump oils, including mineral, synthetic and hydrocarbon blends. We can help you match the right oil and lubricant to your system to ensure low vapor pressure and chemical stability.
