Vacuum Pumps Selection Guide

This guide outlines the applications, features, and performance of various vacuum pumps. Please select a pump based on your specific application and requirements. When choosing a vacuum pump, it is essential to first estimate the necessary pumping speed and then select the appropriate pump type for your process.

Large Dry Vacuum Pumps

A wide range of dry vacuum pumps is available, suitable for everything from demanding industrial processes to lighter laboratory applications. These pumps can be selected based on their intended use and process type. The optimal choice depends on the level of pressure reduction required and the operations to be performed inside the vacuum chamber. The achievable pressure levels are presented in the corresponding performance table. Pump size also varies depending on the volume of the space to be evacuated. Pumping simulations can assist in determining specifications—please consult for further details.

Oil Rotary Vacuum Pumps (Large)

Large oil rotary vacuum pumps are designed for a broad range of applications. Selection depends on both the application type and desired performance characteristics. These pumps are available with various optional accessories to meet different operational needs. Like dry pumps, their pressure capabilities and size depend on the volume being evacuated, and performance can be estimated through simulation.

Available Series:

• VD Series
• VS Series
• PVD Series
• PKS Series
• VS Series

Oil Rotary Vacuum Pumps (Small)

Small oil rotary vacuum pumps are ideal for compact systems requiring efficient evacuation, particularly those below 200 L/min capacity. These units offer excellent performance in limited spaces and are suitable for various laboratory and industrial uses. Pump selection should be based on required vacuum level and intended chamber operation. As with larger systems, simulation can help determine appropriate sizing.

Available Series:

• GHD/GLD Series

Mechanical Booster Pumps

Mechanical booster pumps are offered for applications requiring higher pumping speeds and improved performance in medium vacuum ranges. Depending on the operational setup, air-cooled versions are also available. For detailed selection guidance, please inquire directly.

Turbo Molecular Pumps

These pumps are used for high and ultra-high vacuum applications and are often chosen for their precision and cleanliness. Model selection should be guided by application-specific performance figures. Please refer to product catalogs for detailed specifications.

Sputter Ion Pumps

Sputter ion pumps are widely used for creating ultra-high vacuum conditions, especially in sensitive environments like analytical instruments and particle accelerators. They operate on a simple principle involving an electric field between anode and cathode, eliminating mechanical vibrations and noise. These pumps are oil-free and can be installed in any orientation. Advanced series are available featuring optimized magnetic fields and specialized components to enhance vacuum performance in demanding conditions.

Oil Selection Guide

Using genuine vacuum pump oil ensures optimal pump performance and reliability. High-quality oils extend equipment lifespan, reduce maintenance frequency, and lower operating costs, resulting in improved overall efficiency.
