Page 4: Section 01 - Installation
Where extreme exhaust conditions are encountered it is best to pipe the exhaust direct out of the building. Welch recommended wire reinforced PVC, metal pipe or thick walled rubber hose be used as exhaust lines to avoid potential of line becoming crimped or collapsing resulting in the exhaust port being clocked. - 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 Vacuum, Thomas Industries, inc. 1.172... -
Page 7: High Pressure Operation
Leaky vacuum systems, too large a vacuum chamber for pump size or high gas loads to the vacuum systems are causes for extended runs of the pump at elevated pressure. If you need additional information, please contact Welch Vacuum at 847-676-8800, extension 1, for further information and precautions. 2.22 Principle of Gas Ballast 2.221... -
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
This is why a regular maintenance schedule for the oil is critical to obtain the longest service life out of your DUOSEAL pump. Welch recommends that you examine the condition of the oil on a daily basis in the early days of a new process or experiment. -
Page 10: Oil Changes And Oil Level
3.203 Forced Oil Flushing Procedure 1. Check the oil level, if the oil level is well above the fill mark, (This may indicate either the pump has been overfilled with oil or has ingested a liquid or a large amount of vapor water or organic solvents.) Please go to step 2. -

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. -

Section 7: PUMPING SPEED CURVES HIGH EFFICIENCY PUMPING CHARACTERISTIC OF DUOSEAL® PUMPS The low RPM design of DuoSeal vacuum pumps makes it possible to maintain high pumping efficiencies into the low micron range. High RPM direct drive vacuum pumps, on the other hand, experience a rapid fall off of pumping speed below 100 microns. - Page 16 Section 8: EXPLODED VIEW...
