Torque Wet Cup

The wet cup is torqued at the factory; however, throat packing seals on Severe Duty pumps may relax over time. Check wet cup torque frequently after initial start-up and periodically after the first week of produc- tion. Maintaining proper wet cup torque is important to

extending seal life.

MaxLife pumps use a special u-cup throat seal that is non-adjustable and does not require periodic

torquing.
