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.

Page 6: Section 02 - Operation
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 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
2.225 Controlled Ballast Flow Some degree of variation in ballast fl ow may be obtained by the amount of opening applied tot he gas ballast. Two or more turns of the gas ballast are suffi cient to open it wide. With the gas ballast open, the sound of the exhaust is similar to that of a pump operating against a large leak. -
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. -
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 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. -
Page 12: Section 04 - Trouble Shooting Guide
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. - Page 13 Section 5: QUICK REFERENCE CHARTS Motor Options 1374 1397 Repair Kits Wired for 115V, 60Hz, 1Ph 1374B-01 1397B-01 Minor Repair Kit 1397K-07 Wired for 230V, 60Hz, 1Ph Major Repair Kit 1397K-08 Wired for 230V, 50Hz, 1Ph 1397C-03 Base and Belt Guard Kit 1371F Wired for 230V, 60Hz, 3Ph 1374M-01 1397M-01...

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 effi ciencies 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...
