Heavy-Duty Diaphragm Repair

If your pump uses standard diaphragms, see page 19.

Tools Required

•Torque wrench

•19 mm open end wrench

•O-ring pick

•Lithium-base grease

Disassembly

A Fluid Section Repair Kit is available. Refer to page 27, 35, or 43 to order the correct kit for your pump. Parts included in the kit are marked with an asterisk, for example (401*). Use all the parts in the kit for the best results.

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, always follow the Pres- sure Relief Procedure on page 11.

1.Relieve the pressure.

2.Remove the manifolds and disassemble the ball check valves as explained on page 18.

3.Remove the clamps (106) holding the fluid covers

(101)to the air covers (23). Pull the fluid covers

(101)off the pump. See FIG. 12.

4.Once the fluid covers are removed, the diaphragm on the side of the pump which was last pressurized with air will be separated from the center section/air cover. This allows you to grip the diaphragms.

5.Diaphragms are assembled handtight. To loosen, grip both diaphragms securely around the outer edge and rotate counterclockwise. One diaphragm assembly will come free and the other will remain attached to the shaft. Remove the freed diaphragm

(403)and air side plate (104).

6.Pull the opposite diaphragm assembly and shaft

(24)out of the center housing (1). Hold the shaft flats with a 19 mm open end wrench and remove the diaphragm and air side plate from the shaft.

7.Inspect the diaphragm shaft (24) for wear or scratches. If it is damaged, inspect the bearings (19)

in place. If the bearings are damaged, refer to page 24.

8.Reach into the center housing (1) with an o-ring pick and hook the u-cup packings (402), then pull them out of the housing. This can be done with the bear- ings (19) in place.

9.Clean all parts and inspect for wear or damage. Replace parts as needed.
