Girovac Ltd


NGB pumps are standard NXDS/XDS pumps but with the gas ballast feature removed. They are for applications where it is advantageous to have the control knob and machining removed so that it cannot be accidentally opened. Example applications include rare gas recirculation and gas recovery.


• Lubricant-free within the vacuum envelope and hermetically sealed means a totally clean and dry vacuum to prevent cross contamination.
• Advanced scroll-form and tip-seal technologies deliver best-in-class vacuum performance and unrivalled ultimate vacuum levels.
• Unique tip seal design significantly reduces wear to minimise maintenance and extend service life.
• Quiet operation with typical noise during operation
• Advanced interface providing a variety of traditional and analogue and digital control methods enabling remote control/monitoring via RS232 or RS485.
• Integrated inverter drive with auto sensing input delivers optimised pumping performance globally.
