nXDS dry scroll pumps

Offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise levels than other pumps.

nXDS pumps are designed to be completely field serviceable.

Its intelligent control functions and up to five years service interval ensures low cost of ownership, making it the small dry pump of choice for today's most advanced technologies.

The onboard pump controller allows for:

• Wide range voltage input with automatic selection,
• Easy to use manual control buttons including a standby speed control button for efficient process tuning ... and for more convenient operation a remote control interface.

The nXDS takes scroll vacuum technology to the next level:

Improved performance, exceptional pumping capability, quiet operation and extended service intervals make nXDS the ultimate dry choice!

Pfeiffer HiScroll dry scroll pumps

The HiScroll series consists of three dry and hermetically sealed scroll pumps with a nominal pumping speed of 6 - 20 m3/ h. The pumps are characterized in particular by their high performance when evacuating against atmosphere. Their powerful IPM1) synchronous motors with sensorless INFORM® control2) achieve up to 15% higher efficiency compared to conventional drives.

Lowest noise emission on the market

The pumps are also characterized by their very compact design and extremely quiet and low-vibration operation. Therefore, they are ideal for use in quiet working environments, for example on mass spectrometers, research & development institutes or leak detection systems.

Intelligent control

HiScroll pumps can be easily connected to other Pfeiffer Vacuum products (such as turbopumps or display and control units) as well as to a higher-level external controller, via RS-485 or ProfiNet. The interface enables RPM regulation, situation-specific control of the fan and monitoring of the pump performance. This helps to minimize wear and noise emissions, and ensures longer maintenance intervals.

High safety at lower costs

The integrated two-stage gas ballast and safety valve ensure process-specific and safe operation. The proven quality of Pfeiffer Vacuum components guarantees the long lifetime. Easy maintenance of the pumps enables short service times and the efficient motor helps to reduce electricity costs.

ATEX certification

HiScroll pumps are already certified to ATEX II 3/-G Ex h IIC T4 Gc X +5° C ≤ Ta ≤ +40 °C as standard. This means that HiScroll pumps can be used with internal explosion protection of equipment category 3G for Ex zone 2 with gas types IIC. These versions are only available without the optional integrated pressure sensor, as only ATEX certified accessories may also be used in ATEX applications.
