Model 41-818836 Conductive Acetal Ball Valve Pump   Page 16

DIAPHRAGM  SERVICING

To service the diaphragms first 

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 composite 

repair parts drawing, and the diaphragm 

servicing illustration.

Using a 1/2" wrench or socket, 

remove the 16 capscrews (items 9 & 

10),  and  flanged  nuts  that  fasten  the 

elbows (items 16 and 17) to the outer 

chambers (items 13). Remove the 

elbows with the manifolds and spacers 

attached.

Step #2:

 Removing the outer 

chambers.

Using a 1/2" wrench or socket, 

remove the 16 capscrews (items 9 

and 10), and flanged nuts that fasten 

the outer chambers, diaphragms, and 

intermediate (item 4) together.

Step #3:

 Removing the diaphragm 

assemblies.

Use a 3/4" (19mm) wrench or 

six pointed socket to remove the 

diaphragm assemblies (outer plate, 

diaphragm, and inner plate) from the 

diaphragm rod (item 30) by turning 

counterclockwise.

Insert a 6-32 set screw into the 

smaller tapped hole in the inner 

diaphragm plate (item 27). Insert 

the protruding stud and the 6-32 

fastener loosely into a vise. Use a 

3/4" wrench or socket to remove the 

outer diaphragm plate (item 26) by 

turning counterclockwise. Inspect the 

diaphragm (item 14) for cuts, punctures, 

abrasive wear or chemical attack. 

Replace the diaphragms if necessary.

Step #4:

 Installing the diaphragms.

Push the threaded stud of the outer 

diaphragm plate through the center hole 

of the diaphragm. Thread the inner plate 

clockwise onto the stud. Insert the loose 

assembly with the above 6-32 fastener 

back into the vise. Use a torque wrench 

to tighten the diaphragm assembly 

together to 90 in lbs. (10.17 Newton 

meters) 120 in lbs. Santoprene (13.56 

Newton meters). Allow a minimum of 15 

minutes to elapse after torquing, then 

re-torque the assembly to compensate 

for stress relaxation in the clamped 

assembly.

Step #5:

 Installing the diaphragm 

assemblies to the pump.

Make sure the bumper (item 6) is 

installed over the diaphragm rod.

Thread the stud of the one diaphragm 

assembly clockwise into the tapped 

hole at the end of the diaphragm rod 

(item 30) until the inner diaphragm plate 

is flush to the end of the rod. Insert rod 

into pump.

Align the bolt holes in the diaphragm 

with the bolt pattern in the intermediate 

(item 4).

Fasten the outer chamber (item 

13) to the pump, using the capscrews 

(items 9 and 10) and flanged nuts. 

On the opposite side of the pump, 

pull the diaphragm rod out as far as 

possible. Make sure the bumper (item 

6) is installed over the diaphragm rod. 

Thread the stud of the remaining 

diaphragm assembly clockwise into the 

tapped hole at the end of the diaphragm 

rod (item 30) as far as possible and 

still allow for alignment of the bolt 

holes in the diaphragm with the bolt 

pattern in the inner chamber. Install 

diaphragms with convolutions facing 

towards center of pump. See sectional 

view on previous page.

Fasten the remaining outer chamber 

(item 13) to the pump, using the 

capscrews (items 9 and 10) and flanged 

nuts.

Step #6:

 Re-install the elbow/

spacer/manifold assemblies to the 

pump, using the capscrews (items 9 & 

10) and flanged  nuts.

The pump is now ready to be  

re-installed, connected and returned to 

operation.

OVERLAY DIAPHRAGM SERVICING

 

The overlay diaphragm (item 15) is 

designed to fit snugly over the exterior of 

the standard TPE diaphragm (item14). 

 

Read these instructions 

completely, before in- 

stallation and start-up. 

It is the responsibility of 

the purchaser to retain 

this manual for reference. Failure to 

comply with the recommendations stated 

in this manual will damage the pump, and 

void factory warranty.
