Scroll Pumps Vs Rotary Vane Pumps

In the world of vacuum pumps, innovation is key. Our video shares a short comparison on why our PSP12 Scroll Pump takes the lead ahead of rotary vane pumps.

The CryoDry® PSP12 Scroll Vacuum Pump is an efficient and reliable pump for your freeze drying needs. It boasts a powerful pumping speed of 12 m3/h and ultimate vacuum of 8×10-3 mbar, making it a great replacement for rotary vane pumps.


The PSP12 Scroll Pump excels in efficiency, providing higher pumping speeds and lower energy consumption.


With fewer moving parts, Scroll Pumps offer enhanced reliability and longer service life.

Service Intervals Comparison

Service for the PSP12 Scroll Pump is needed every 12,000 usage hours or 2 years – whichever comes first which means lifetime costs are lower. Whereas rotary vane pumps require oil changes every six months or after 3,000 use hours which can add up over time.


The PSP12 Scroll Pump is lubricant-free, keeping your product free from contamination with hydrocarbons. The oil-free design eliminates the need for frequent oil changes, oil mist filter replacements, and costly waste oil disposal.

Reduced Vibration and Noise

Along with being sealed tight using joint spiral scrolls, the PSP12 creates less vibration and noise which makes it quieter.

With a noise level of less than 54 dB(A), the PSP12 operates quietly, making it a great addition to any laboratory or facility.
