The document provides comprehensive specifications and operational guidelines for Edwards' CDX1000 and IDX1000/IDX1300 dry vacuum pumps, including flameproof and safe area versions. It addresses ATEX compliance for systems requiring it and offers general information on pump motors, with specific details available in a separate manual.
The manual includes operating conditions, performance metrics, mechanical and electrical data, lubrication, and cooling requirements. It also details materials of construction and connection specifications.
Guidelines for safe unpacking, inspection, and pump location are outlined, along with instructions for connecting sensors, electrical supply, and cooling systems. Commissioning procedures and leak testing are also covered.
Operational safety measures and system control for both ATEX and non-ATEX systems are discussed. Procedures for starting, warming up, and shutting down the pump are provided.
The document outlines safety information and a maintenance plan, including checks for oil levels, coolant levels, and shaft-seals purge gas supply. Instructions for removing and replacing components like the inlet filter are included.
The product complies with EU directives on machinery safety, ATEX, RoHS, and REACH regulations. Material exemptions and hazardous substance declarations are specified, particularly concerning lead content.
Figures illustrate the components of the IDX and CDX pumps, including the pump motor, gearbox vent filter, heat exchanger, and other essential parts for operation and maintenance.
Operating conditions include ambient temperatures from -20 to 40°C, with a maximum humidity of 90% RH and altitude of 1000 m. The pumps have a minimum pumping speed of 800 m3/h and a maximum outlet pressure of 1.15 bar. Lubrication and cooling systems are specified, with Mobil SHC 629 recommended for oil.
CDX pumps are suitable for hazardous areas with specific certifications, while IDX pumps are for safe areas only. Prohibited uses include using the pump as a compressor or in explosive atmospheres.
Various accessories are available for specific applications. Maintenance guidelines include using specific cleaning solutions and coolant types.
The document emphasizes compliance with safety standards, including ATEX directives for hazardous environments, and provides warnings against misuse that could lead to safety hazards.
Coolants must be amine-free, automotive-grade ethylene glycol antifreezes, diluted to 35%-50% with water. Edwards recommends using their own coolant for optimal corrosion protection.
Construction materials include SG iron for stators, rotors, and gear covers, steel for bearings and gears, and stainless steel for seals and flame arrestor elements.
Installation must be performed by trained technicians. Safety clothing is required when handling contaminated components. Proper leveling and securing with bolts are crucial to prevent distortion and overheating.
Leak-test the system post-installation and seal any leaks. The pump's leak rate is tested to be less than 1 x 10-3 mbar l s-1. Commissioning involves isolating the pump, turning on cooling and purge systems, checking for leaks, and adjusting the TCV for temperature control.
The CDX pump can handle flammable vapors and must be operated with a shaft-seals purge in ATEX systems. Maintain pump case temperature below specified limits to prevent automatic shutdown.
Maintenance frequency should be adjusted based on process conditions. Clean processes may require less frequent maintenance, while harsh processes may necessitate more frequent checks.
Regularly check the oil levels in the gearbox and end cover. If oil levels are frequently low or there is a sudden loss, it may indicate a fault, and the pump should be shut down for inspection.
A maintenance plan outlines tasks with recommended frequencies, such as weekly oil level checks, monthly inspections of bleed filters, and yearly cleaning of the cooling system.
Instructions are provided for checking and refilling coolant levels, with warnings about pressure release and potential overheating.
Regular inspections of all pipelines and connections are necessary to ensure they are not corroded or damaged.
Annual oil and filter changes are recommended, with detailed steps for draining and refilling oil, cleaning sight-glasses, and replacing filters.
Other tasks include removing inlet filters after initial operation, inspecting process and exhaust pipelines, and replacing components like the pump motor and flexible coupling insert as needed.
If storing the pump in temperatures below -14°C (7°F), drain oil and coolant. Ensure the pump is shut down, disconnect from electrical supply, and store in clean, dry conditions. Dispose of the pump and related materials safely, adhering to local and national safety and environmental regulations.
Edwards products and services are available globally. Spare parts should be ordered with specific model and item numbers. A global network of service centers offers decontamination, repair, and rebuild services.

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....
