Setup

Wet Cup

Before starting, fill the wet cup (R) 1/3 full with Graco Throat Seal Liquid (TSL) or compatible solvent.

The enclosed wet cup has a fill port in the cover.

Setup

To torque the wet cup, use the following steps.

1.Follow Pressure Relief Procedure on page 12.

2.Use the packing nut wrench (supplied) to torque the wet cup; see the following table for torque values. Do this whenever necessary. Do not overtighten the wet cup.

Displacement Pump	Torque

100cc, 60cc	28-44 ft-lbs (38-59 N•m)

200c, 250cc, 500cc	95-115 ft-lbs (128-155 N•m)

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.
