Attach Second Fluid Cover

To reduce the risk of serious injury, do not put your fingers or hand between the air cover and the diaphragm.

To ensure proper seating and help attain expected diaphragm life, attach the second fluid cover with air pressure on the pump. This procedure is needed for overmolded diaphragms (PO and CO) and for the following standard diaphragms: TP, SP, GE, PT.

1. Place the supplied tool (302) where the air valve gasket (113*) normally goes. Arrows (A) must face toward the fluid cover that is already attached.

NOTE: If you are replacing the diaphragms but not the air valve, you still must remove the air valve, and replace the gasket with the tool so the air valve can be used for proper installation of the second fluid cover. Remember to remove the tool and replace the gasket when finished.

Reassembly of Overmolded Diaphragms

NOTE: If your pump has standard diaphragms, see

page 16.

1. Clamp the shaft flats in a vise.

2. If diaphragm setscrew comes loose or is replaced, apply permanent (red) Loctite

phragm side threads. Screw into diaphragm until tight.

3. Assemble the air side plate (14) and washer (18) onto the diaphragm. The rounded side of the plate must face the diaphragm.

4. Apply medium-strength (blue) Loctite or equivalent to the threads of the diaphragm assembly. Screw the assembly into the shaft as tight as possible by hand.

or equivalent to dia-

IG. 8. Diaphragm Installation Tool

2. Reattach the air valve.

3. Supply the pump with low pressure air, just enough to move the diaphragm. For standard diaphragms, use about 10 psi (0.07 MPa, 0.7 bar); for overmolded diaphragms use about 20 psi (0.14 MPa,

1.4 bar). Shop air may be used. The diaphragm will shift so the second fluid cover will seat properly. Keep air pressure on until the second fluid cover is attached.

4. Attach the second fluid cover (2). See Torque Instructions, page 20.

5. Grease the shaft u-cups (101*) and the length and ends of the diaphragm shaft (108*). Slide the shaft into the housing.

6. Reattach the first fluid cover (2). Arrow (A) must point toward the air valve. See Torque Instruc- tions, page 20.

7. Repeat Steps 2 - 4 for the other diaphragm assembly.

8. Follow directions under Attach Second Fluid Cover, page 19.

9. Reassemble the ball check valves and manifolds as explained on page 12.

5. Remove the air valve and the tool (302), replace the

gasket (113), and reattach the air valve. See Torque Instructions, page 20.

Torque Instructions

See FIG. 9 for fluid cover and air valve fasteners. See F

IG. 10 for manifold fasteners.

NOTE: Fluid cover and manifold fasteners on the polypropylene pumps have a thread-locking adhesive patch applied to the threads. If this patch is excessively worn, the fasteners may loosen during operation. Replace screws with new ones or apply medium-strength (blue) Loctite or equivalent to the threads.

If fluid cover or manifold fasteners have been loosened, it is important to torque them using the following procedure to improve sealing.

NOTE: Always completely torque fluid covers, then torque the manifold pieces together, then torque the assembled manifolds to the fluid covers.

Start all fluid cover screws a few turns. Then turn down each screw just until head contacts cover. Then turn each screw by 1/2 turn or less working in a crisscross pattern to specified torque. Repeat for manifolds.

Fluid cover fasteners:

Polypropylene and Stainless Steel: 40-45 ft-lb

(54-61 N•m)

Aluminum: 55-60 ft-lb (75-81 N•m)

Manifold fasteners: Polypropylene: 40-45 ft-lb (54-61 N•m) Aluminum:

Refs 1-8: 11-21 ft-lb (15-28 N•m) Refs 9-16: 55-60 ft-lb (75-81 N•m)

Stainless Steel:

Refs 1-4: 110-120 in-lb (12-13 N•m) Refs 5-12: 40-45 ft-lb (54-61 N•m)

Retorque the air valve fasteners in a crisscross pattern to specified torque.

Air Valve fasteners

Plastic Center Sections: 45-55 in-lb (5-6.2 N•m) Aluminum Center Sections: 75-85 in-lb

(8.5-9.6 N•m)

Also check and tighten the nuts or bolts (X) holding the manifold feet to the mounting brackets.
