Page 4: Section 01 - Installation
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.

1.17 Traps (See Accessory section in the back of this manual.) 1.171 The need for a Trap Where corrosive vapors or large quantities of condensable vapors are evolved from vacuum processing, a cold trap may be used in the connecting line to the pump. It will help prevent damage to the pump mechanism and reduce oil contamination. -
Page 7: High Pressure Operation
2.20 Operation and System Optimization 2.21 High Pressure Operation DUOSEAL two-stage pumps are designed to be most efficient 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. When the pump is operated at elevated pressures up to about 10 Torr for long periods of time, the pump will run hotter. -
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 efficiency 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. -
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. -
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. -

Section 4: TROUBLE-SHOOTING GUIDE 4.10 Poor Vacuum Readings 1. Disconnect vacuum pump from your vacuum system. 2. Obtain 1 gallon of DUOSEAL oil, 1 gallon or larger clear plastic container, clear drain hose (1/4 inch ID by at least 2.5 feet long), rubber gloves, goggles, apron and pliers. 3. -

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 FOR MODEL 1376Z-46...
