Edwards Small Oil/Dry Vacuum Pumps

nXDS_Dry_scroll_pumpsThe nXDS range is the next generation in completely oil free, dry scroll pumps and replaces the XDS range.  nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power consumption and lower noise.  Gas ballast allows for pumping of condensable vapours including, water, solvents, dilute acids and bases.  nXDS pumps also feature the latest in tip seal technology giving significantly longer life between tip seal changes.  Integrated inverter drive with auto sensing voltage input delivers optimized pumping performance globally. nXDS pumps are designed to be completely field serviceable.   Interesting scroll pumps You tube videos: nXDS tip seal change and nXDS preview.

E2M0.7 and 1.5 Oil Sealed Rotary Vane Pumps

Small EM series pumps are rugged mechanical oil-sealed pumps with speeds of 0.7 and 1.5 m3/hr. Compact and quiet, they feature advanced lubrication circuits, high reliability, and accessories to suit specific application needs.

The Edwards RV series have become the industry standard for scientific primary pumping applications.  RV pumps are uniquely capable of delivering high or low throughputs with high ultimate vacuum.  This, combined with ultra-low noise levels, makes them ideal for a wide range of applications including GCMS and other small bench top type applications.

All pumps are approved to UL and CSA standards by an external test house.  Pumping speeds ranging from 3 to 12 m3/hr.

The EM range of oil-sealed rotary pumps - renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour - have become the industry standard for laboratory and light industrial applications.  

The E1M18 and E2M18 pumps are direct drive, sliding vane pumps.  The pump is oil sealed and designed for reliable, long-term operation.  The pump is a freestanding unit with the drive provided through a flexible coupling by either a single phase or three phase (four pole) motor.  Medium EM series pumps are rugged mechanical oil-sealed pumps with speeds of 18 and 28 m3/hr. 

ATEX RV pumps have an external ATEX classification of Ex II 2G IIC T4 or Ex II 2G IIB T4 ans are suitable for use in potentially explosive atmospheres.  The share the small internal ATEX classification as the standard RV pumps, namely EX II3G c IIB T4.  

ATEX pumps with flameproof motors require the user to provide 2 off hazardous area cable glands and cables. In addition, connection of the thermistors to an appropriate safety circuit must be made to switch off the pump if overheating occurs.  The pumps are supplied with the gas ballast port plugged.  When pumping flammable gasses or vapours you must fit an inert gas purge to this port to dilute such gases or vapours below the lower explosive limit.  

D-LAB Rotary Pumps

The Edwards D-LAB membrane pumps with their chemically resistant Teflon heads, diaphragms and Kalrez valves offer the chemical or pharmaceutical laboratory user a wide range of choice, either used as stand-alone pumps or as part of a sophisticated system.  The one head, 100 mbar ultimate vacuum pumps are suitable for use with drying equipment or for replacing water jet pumps, whilst the two head, 8 mbar ultimate vacuum pumps are suitable for rotary evaporation, gas transfer and a wide range of medium vacuum applications. 

Edwards Diaphragm Pumps

Diaphragm Pumps

The Edwards XDD1 diaphragm pumps are used for backing small compound turbo molecular pumps in clean, high vacuum applications, They comply with EN61010, EN1012, CSA/UL and are designed to be free standing bench top units. The a.c. voltage motor can be sued on worldwide supplies ranging form 100 to 115V, and 200 to 230V.  The d.c voltage motor runs on 24V via a 15 pin DIN connector.  By selecting the appropriate mode the pump speed can be controlled by the user to provide variable pumping speed.  This version is suited to the customer who is building their own system.
