EDWARD Edward vacuum pump oil-free dry scroll pump 20I electric backing pump scan

product description
The nXDS pump is improved on the basis of the traditional XDS pump, increasing the pumping speed and reducing ultimate pressure, power consumption and noise. Gas ballast allows the pumping of condensable vapors including water, solvents, dilute acids and bases. nXDS pumps also feature the latest end seal technology, which significantly extends the time between end seal replacements. An integrated frequency converter drive with automatic voltage input sensing provides overall optimized pumping performance, and nXDS pumps are fully field serviceable.
The nXDS6i is the next generation of completely oil-free dry scroll pumps and replaces the XDS5. Compared with traditional XDS pumps, nXDS has stronger performance, higher pumping speed, lower ultimate pressure, lower power consumption and lower noise. Gas ballast allows the pumping of condensable vapors including water, solvents, dilute acids and bases. nXDS also features the latest in end seal technology, significantly extending the time between end seal replacements. Integrated frequency converter drive with automatic voltage input sensing provides overall optimized pumping performance nXDS pumps are fully field serviceable.
The nXDS10i is the next generation of completely oil-free dry scroll pumps and replaces the XDS10. nXDS improves the performance of traditional pumps with higher pumping speeds, lower ultimate pressures, lower power consumption and less noise. Gas ballast allows the pumping of condensable vapors including aqueous solvents, dilute acids and alkalis. nXDS also features the latest in end seal technology, significantly extending the time between end seal replacements. An integrated frequency converter drive with automatic voltage input sensing provides overall optimized pumping performance, and the nXDS is fully field serviceable.
The nXDS15i is the next generation of completely oil-free dry scroll pumps that can replace comparably sized dry pumps and mid-size oil-sealed pumps in a variety of applications. nXDS improves the performance of traditional XDS pumps with higher pumping speed, lower ultimate pressure, lower power consumption and less noise. Gas ballast allows the pumping of condensable vapors including water, solvents, dilute acids and bases. nXDS also features the latest end seal technology, which significantly extends the time between end seal replacements. An integrated frequency converter drive with automatic voltage input sensing provides overall optimized pumping performance, and the nXDS is fully field serviceable.
The nXDS20i is the next generation of completely oil-free dry scroll pumps that can replace equivalent sized dry pumps and mid-sized oil sealed pumps in a variety of applications. nXDS improves the performance of traditional XDS pumps with higher pumping speed, lower ultimate pressure, lower power consumption and less noise. Gas ballast allows the pumping of condensable vapors including water, solvents, dilute acids and bases. nXDS also features the latest in end seal technology, significantly extending the time between end seal replacements. An integrated frequency converter drive with automatic voltage input sensing provides overall optimized pumping performance, and the nXDS is fully field serviceable.

Feature

• lubricants are required in the vacuum housing, and the complete seal ensures a thorough clean and dry vacuum, preventing cross-contamination
• The non-atmospheric pressure to vacuum shaft seal can completely isolate the bearing, thereby preventing process attacks, and the bearing can also run at a lower temperature and last longer
• Improved motor and transmission efficiency, which can reduce power consumption and operation costs
• Advanced interfaces provide a variety of traditional, analog and digital controls
