This manual provides installation, operation and maintenance instructions for the Edwards CDX1000 chemical dry vacuum pumps and the IDX1000 and IDX1300 industrial dry vacuum pumps. The pump must be used as specified in this manual. Read this manual before installing and operating the pump. Important safety information is highlighted as WARNING and CAUTION instructions; these instructions must be obeyed. The use of WARNINGS and CAUTIONS is defined below. WARNING Warnings are given where failure to observe the instruction could result in injury or death to people. CAUTION Cautions are given where...

The CDX and IDX pumps are rugged, reliable dry vacuum pumps designed specifically for use in the chemical and pharmaceutical industries, and in industrial processing applications. The CDX and IDX pumps are single stage pumps which use the screw principle, in which a pair of intermeshing, noncontacting rotors are held in correct phase relation by a pair of timing-gears. The gears and the double-row angular contact ball bearings are oil lubricated. The double-ended design means that the bearings, seals and gearbox remain at atmospheric pressure, and that axial loading on the bearings is minimal....

Connect the shut-down thermal snap-switch to a suitable control circuit to shut down the pump if it overheats: refer to Section 3.7. Connect the two pressure switches to a suitable control circuit to shut the pump down if either of the oil circuits loses pressure. This is most easily done by wiring them in series. The shut-down thermal snap switch can be wired in series with the two pressure switches to shut down the pump if any one of the three switches trip. Connect the warning thermal snap-switch to the control equipment to provide an indication that the pump is too hot: refer to Section 3.7....
