nXQi Dry Multistage Roots Pumps
nXQ55i Dry Multistage Roots Pump
This helps minimise gas loss and maintain consistent operation, which is essential in environments where secure gas containment matters. Its dry, dust‑free design supports clean processes, protecting gas purity and system integrity. With strong capability on light gases such as helium‑3 and helium‑4, the nXQ55i delivers stable performance in helium cryostats, dilution refrigeration systems, leak detection setups and other sensitive applications that depend on reliable, repeatable containment.
Features and benefits
- Leak-tight design
The nXQ55i is developed to satisfy leak-tightness standards, achieving rates below 5×10⁻⁸ mbar·l/s. As part of a rigorous quality process, each nXQ55i is subjected to an integral leak test, and every pump is supplied with a certificate confirming the test has been successfully completed and validated. This guarantees reliability and customer confidence.
- Strong light gas performance
Engineered for rare gases such as helium-3 and helium-4, the nXQ55i delivers high pumping speed (up to 52 m³/h for helium) supporting efficient recovery and recirculation in demanding environments. This ensures stable operation even under continuous use, making it suitable for applications where gas purity and conservation are important.
- Dry pump design
Its compact dry pump design is dust-free, ensuring clean processes and results while avoiding unpleasant odours and particulates for a more comfortable working environment. Low noise levels, reduced energy consumption, and the absence of oil changes or disposal requirements make it a cleaner alternative to traditional “wet” pumps. With low maintenance requirements for up to 5 years, the nXQ55i contributes to reduced downtime and, ultimately, a low cost of ownership.
