THIS BOOK WAS NOT WHAT I EXPECTED FROM A HANDBOOK. THE INFORMATION IS VERY, VERY GENERAL. THERE ARE NO EQUATIONS OR CHARTS. THERE IS AN EXTENSIVE TABLE OF SEAL MATERIALS FOR VARIOUS FLUID SERVICES. IT COVERS ONLY GENERALLY ACCEPTED DESIGN, OPERATIONAL, AND SERVICE CRITERIA. THIS BOOK PROBABLY COULD BE USED BY AN ENGINEER LOOKING FOR GENERAL INFORMATION FOR A POTENTIAL APPLICATION OF MECHANICAL SEALS. THIS BOOK IS VERY LIGHT READING AND IS, AT BEST, A BASIC INTRODUCTION TO MECHANICAL SEALS. I WAS CONSIDERING BUYING IT BUT FORTUNATELY I BORROWED IT FROM A LIBRARY. DO NOT BUY IT, BORROW IT FROM A LIBRARY.
