DIAPHRAGM SERVICING

To service the diaphragms irst shut

off the suction, then shut off the

discharge lines to the pump. Shut off the

compressed air supply, bleed the

pressure from the pump and disconnect

the air supply line from the pump. Drain

any remaining liquid from the pump.

Step #1: See the pump assembly

drawing and the diaphragm servicing

illustration.

Using a 1/2" wrench or socket,

remove the 16 capscrews (item 9) that

fasten the manifolds (items 19 & 20) to

the outer chambers (item 13).

S t e p # 2 : R e m o v i n g o u t e r

chambers.

Using a 1/2" wrench or socket,

remove the 16 capscrews (item 10), that

fasten the outer chambers (item 13),

diaphragms (item 14) and intermediate

(item 5) together.

Step #3: Removing the dia-

phragms and diaphragm plates.

Use a 7/8" wrench or six point

socket to remove the outer diaphragm

plate assemblies (item 24), diaphragms

(item 14) and inner diaphragm plates

(item 23) from the diaphragm rod

(item 27) by turning counterclockwise.

Inspect the diaphragm for cuts, punctures,

abrasive wear or chemical attack.

Replace the diaphragms if necessary.

DO NOT USE A WRENCH ON THE

DIAPHRAGM ROD. FLAWS ON THE

SURFACE MAY DAMAGE BEARINGS

AND SEALS.

S t e p # 4 : A s s e m b l i n g t h e

diaphragm and diaphragm plates to the

diaphragm rod.

Push the threaded stud of one outer

diaphragm plate assembly through the

center of one diaphragm and through

one inner diaphragm plate. Install the

diaphragm with the natural bulge facing

away from the diaphragm rod and make

sure the radius on the inner diaphragm

plate is towards the diaphragm, as

indicated on the diaphragm servicing

illustration. Thread the assembly onto

the diaphragm rod, leaving loose.

Step #5: Installing the diaphragm

and rod assembly to the pump.

Make sure the bumper (item 6) is

installed over the diaphragm rod. Insert

rod into pump.

On the opposite side of the pump,

pull the diaphragm rod out as far as

possible. Make sure the second bum-

per is installed over the diaphragm rod.

Push the threaded stud of the other

outer diaphragm plate assembly through

the center of the other diaphragm and

through the other inner diaphragm

plate. Make sure the radius on the inner

diaphragm plate is towards the

diaphragm. Thread the assembly onto

the diaphragm rod. Use a 7/8" wrench

or socket to hold one outer diaphragm

plate. Then, use a torque wrench to

tighten the other outer diaphragm plate

to the diaphragm rod to 500 in. lbs.

(56.5 Newton meters).

Align one diaphragm with the

intermediate and install the outer

chamber to the pump using the 8

capscrews. Tighten the opposite

diaphragm plate until the holes in the

diaphragm align with the holes in the

intermediate. Then, install the other

outer chamber using the 8 capscrews.

Step #6: Reinstall the manifolds to the

pump using the 16 capscrews.

The pump is now ready to be

reinstalled, connected and returned to

operation.

OVERLAY DIAPHRAGM SERVICING

The overlay diaphragm (item 15)

is designed to it over the exterior of the

standard diaphragm (item 14).

Follow the same procedures

described for the standard diaphragm

for removal and installation, except tight-

en the outer diaphragm plate assembly,

diaphragms and inner diaphragm plate

to the diaphragm rod to 500 in. lbs.

(56.5 Newton meters).
