Capacities given are nominal at maximum 60 cycle
speed, based on 26" HgV inlet pressure |
|
|
All capacities and curves are based on dry air
performance with 60 degree F seal water temperature |
Use of Mechanical Seals Offer Many Benefits:
 |
Improved shaft stiffness |
|
|
Reduced shaft length resulting in shorter overall pump
length |
|
|
Prevents pump water leakage to shaft bearings |
|
|
Prevents atmospheric air leakage into low pressure areas
of pump |
|
|
Reduced maintenance
