nXDS pump improve on the basis of traditional XDS pumps, improve the pumping speed , reducing the ultimate pressure , power consumption and noise. Pumping condensable gas ballast allows vapor , including water , solvents, dilute acids and alkalis . nXDS pump also uses the latest end sealing technology, significantly extending the tip seal replacement intervals. Integrated input voltage inverter with automatic sensing function driver optimized to provide the overall pumping performance , nXDS pump can be completely on-site maintenance.
Features and Benefits :
• vacuum enclosure without using a lubricant , completely sealed to ensure thorough cleaning and dry vacuum , to prevent cross- contamination
• No pressure to vacuum seal allows complete isolation bearings , thereby preventing the attack process , the bearing can be run at lower temperatures, the use of longer
• Simple one-sided roller layout and innovative design combined motor and bearings , just the minimum level of special tools , you can achieve easy field service , thus reducing operating costs as much as possible uptime
• Improved motor and transmission efficiency, reduces power consumption and operating costs
• Advanced interface provides a variety of traditional , analog and digital control method , which enables remote control via USB, RS232 or RS485 / monitor
