When developing modern screw vacuum pumps the reduction of energy consumption has been given a high focus— it is now at about the same level of established oil-sealed rotary vane pumps or rotary piston pumps.
To energy savings through modern screw vacuum pumps, similar opportunities arise when using modern Roots pumps or with an optimized operation of rotary vane pumps. Apart from this, the established diffusion pump technology has been improved upon featuring a modern and retrofit power control unit that offers a reduction in the energy demand of these pumps by up to 30%.
In fore-vacuum applications, dry screw pumps have proven themselves even under rugged conditions. They offer a higher degree of robustness and insensitivity towards dust, particles, and vapors at significantly lower maintenance cost.
