\n Dry scroll pumps <\/h4>\n
\n

These pumps operate using two interlocking spiral scrolls, one orbiting and one fixed. As the orbiting scroll rotates it creates pockets of gas that are compressed towards the centre where the gas in expelled, creating a vacuum.
\nOil-free and compact these pumps provide clean and efficient vacuum generation. <\/p>\n

Our range of dry scroll pumps include:
\nmXDS, nXDS\/XDS scroll pumps with pumping speeds going up to 46 m\u00b3h\u207b\u00b9.<\/p>\n <\/div>\n <\/div>\n <\/div>\n

\n Dry screw pumps <\/h4>\n
\n

By rotating two parallel non-contacting helical screw rotors in opposite directions, these pumps trap and compress gas as the screws turn. This moves the gas from the inlet to the exhaust port without the use of lubricants or sealing fluids.
\nEfficient and clean our dry screw pumps include:<\/p>\n

EDS pumps are available in variants ranging from 210 and 460 m\u00b3h\u207b\u00b9 and GXS this range delivers pumping speeds between 160 \u2013 1900 m\u00b3h\u207b\u00b9.
\nBoth ranges of pumps can be further enhanced with the addition of the Stokes 6\u201d mechanical booster pump.<\/p>\n <\/div>\n <\/div>\n <\/div>\n

\n Multi-stage roots pumps <\/h4>\n
\n

Multi-stage Roots pumps utilize multiple pairs of counter-rotating, lobed rotors mounted on a shared shaft within a single pump housing. As these rotors turn in opposite directions, they trap gas between the rotors and the stationary housing (also referred to as the stator), transporting it through successive stages. Each stage incrementally increases the pressure of the gas, effectively compressing it without internal contact between moving parts. This design ensures a clean, oil-free operation with minimal wear and maintenance.<\/p>\n

The compact and energy-efficient nature of these pumps makes them ideal for laboratory environments. Our range includes models such as the nXR30i with a pumping speed of 30 m\u00b3h, and the nXR120i offering 120 m\u00b3\/h, catering to various application needs.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/td>\n <\/tr>\n <\/tbody>\n
