Section 1: INSTALLATION 1.10 Introduction This manual has been complied not only for the care and maintenance of the DUOSEAL pump now in your possession but as a helpful reference and guide for many problems which are usually associated with mechanical vacuum pumps. - Page 5 1.15 Electrical Power 1.151 Power Source Review Review the power source and the motor rating to be sure they agree in voltage, phase and frequency. On three- phase applications the direction of rotation of the motor must be considered. Make a momentary check rotation at the time of power installation and wiring.

Commonly used refrigerants are liquid nitrogen or dry ice and acetone. The refrigerant to be used depends upon the freezing point of the contaminations. A variety of cold traps are available from Welch-Ilmvac. 1.172 The care of a Trap When using a cold trap the refrigerant should be maintained at a high level in the fl... -
Page 7: Operation And System Optimization
2.20 Operation and System Optimization 2.21 High Pressure Operation DUOSEAL two-stage pumps are designed to be most effi cient when operated at or near their ultimate blanked off pressure. The pump is designed to remove air from a vacuum system at atmospheric pressure to a deep vacuum. -
Page 8: System Leaks - Impact And Detection
2.226 Other Forms of contamination control The application of the gas ballast is a moderate and very successful method for the removal of condensable vapors. For very heavily laden systems, other means of removal such as oil separators may be required. For mild cases of contamination the simple expedient of a cold trap or a change of oil serve the purpose. -
Page 9: Section 03 - Maintenance
Section 3: MAINTENANCE 3.10 Vacuum Problems 3.101 Pressure Determinations Leakage, contamination and unusual outgassing are the general causes of problems associated with poor vacuum. To operate at maximum effi ciency a system must be thoroughly clean. If the system is completely clean and free from leaks, and unwarranted vacuum problems still exist, the pump should be checked. -

3.203 Forced Oil Flushing Procedure 1. Check the oil level, if the oil level is well above the fi ll mark (This may indicate either the pump has been overfi lled with oil or has ingested a liquid or a large amount of vapor water or organic solvents). Please go to step 2. -
Page 11: Repairing Oil Leaks
3.40 Repairing Oil Leaks 3.41 Location, Cause and Effect Oil leaks may develop wherever two mating faces are sealed with a gasket. Such seams may fail as the result of deterioration of the gasket material, loosening of the screws caused by temperature variations, or improper care as the result of previous reassembly. -
