Used Vacuum Pumps

At JM Industrial, we buy and sell used and surplus vacuum pumps from top industry brands such as Edwards, Ruvac/Roots, Flowserve SIHI Germany GmbH, Total Maintenance Solutions, and more.

Vacuum pumps are mechanical devices that create and maintain low-pressure environments in several applications. These pumps remove air and gas molecules from the sealed area, reducing the pressure and creating a vacuum. This can be done by creating a pressure differential, where the outside pressure exceeds the pressure inside the system. This causes air and gas molecules to move from a higher to lower pressure area, effectively creating a vacuum. You can buy surplus and used vacuum pumps with your required specifications based on the application, operating environment, and other factors. Browse our wide range inventory to find the appropriate used pumps for sale. Get in touch with our experts to learn more about our products.

How Do Vacuum Pumps Work?

Vacuum pumps are vital in creating controlled environments by eliminating gas molecules from enclosed spaces, resulting in low-pressure or vacuum conditions. These pumps draw in gas through an inlet port during the intake phase. Subsequently, as the pump’s rotor with vanes rotates, the gas undergoes compression, and the pressurized gas is expelled through an outlet port in the exhaust phase. Lubrication is often employed to minimize friction and establish an effective seal between the vanes and the pump housing. While various vacuum pump designs exist, their ultimate objective remains consistent, which is reducing the pressure within a system by extracting gas molecules.

Types of Vacuum Pump at JM Industrial

There are several types of surplus and used vacuum pumps provided by JM Industrial. Our comprehensive inventory of used vacuum pumps comes in diverse specifications.

  • Pneumotive Vacuum Pump: This type of vacuum pump operates using compressed air or gas to create suction. It utilizes the Venturi effect, where the flow of compressed air or gas creates a vacuum by drawing in and entraining the surrounding air.
  • Single Stage Liquid Ring Vacuum Pump: This type of vacuum pump utilizes a liquid ring, typically water, to create the vacuum. The pump impeller rotates within a cylindrical casing, creating a liquid ring that acts as a seal. As the impeller rotates, it draws in gas and compresses it, resulting in a vacuum.
  • Two-Stage Liquid Ring Vacuum Pump: Similar to the single stage liquid ring vacuum pump, this type of pump also uses a liquid ring to create the vacuum. However, it consists of two consecutive stages of impellers. The first stage compresses the gas, and the second stage further compresses it to achieve a higher vacuum level.
  • Two-Stage Rotary Vane Vacuum Pump: This type of vacuum pump consists of two stages of rotary vane assemblies. The rotary vane design involves vanes (blades) mounted on a rotor that rotates within a housing. As the rotor spins, the vanes trap gas and compress it, resulting in a vacuum. The two-stage configuration allows for improved vacuum performance.
  • Vacuum Pump Package: A vacuum pump package refers to a complete system that includes a vacuum pump along with other components necessary for its operation. These packages typically include items such as an electric motor, coupling, baseplate, and sometimes additional accessories like filters, control valves, and gauges.

How to Choose Vacuum Pumps for Your Applications?

Several factors need to be considered while choosing the right vacuum pump for your application. Here are some important ones.

  • Operating Pressure Range: It is important to determine the required vacuum level for your application. Several pumps can achieve a range of pressures from low to high and ultra-high. The pump should meet and maintain the desired pressure range.
  • Pumping Speed: Another important consideration is the speed of the pump. It is defined as the volume of gas it can remove per unit of time. The pumping speed must match the desired evacuation time and the gas load for your application.
  • Gas Compatibility: Before selecting the vacuum pump, ensure the type of gases you work with. Different pumps are designed to handle different types of gases. Some are ideal for general uses, while others are designed for handling corrosive and highly reactive gases. The pump materials and seals must be compatible with the gases used. 
  • Noise and Vibration: Evaluating the pump’s noise and vibration level is another important consideration. If your application demands a stable working environment, select a pump with low noise and vibration characteristics.
  • Maintenance and Reliability: Thorough evaluation of the pumps structural and functional accuracy is essential for maintenance and reliability. Consider factors such as the longevity of consumable parts, the ease of maintenance procedures, the availability of spare parts, and the reputation of the manufacturer. Prioritizing these aspects ensures that your chosen pump will perform effectively and provide long-term reliability, minimizing downtime and maximizing productivity.
  • Cost: It’s essential to evaluate the cost effectiveness of the vacuum pump in terms of its performance, features, and long-term operating costs. Look beyond the initial purchase price and consider factors such as energy efficiency, maintenance requirements, and the potential for future upgrades or expansions. A pump that offers a higher upfront cost but delivers superior performance and energy efficiency may result in long-term cost savings.
