Step 1: 

With manifolds and outer chambers 

removed, remove diaphragm assemblies from 

diaphragm rod. 

DO NOT

 use a pipe wrench or similar 

tool to remove assembly from rod. Flaws in the rod 

surface may damage bearings and seal. Soft jaws 

in a vise are recommended to prevent diaphragm 

rod damage.

Step 1.A: 

NOTE: 

Not all inner diaphragm plates 

are threaded. Some models utilize a through hole 

in the inner diaphragm plate. If required to separate 

diaphragm assembly, place assembly in a vise, 

gripping on the exterior cast diameter of the inner 

plate. Turn the outer plate clockwise to separate the 

assembly.

Always inspect diaphragms for wear cracks or 

chemical attack. Inspect inner and outer plates for 

deformities, rust scale and wear. Inspect intermediate 

bearings for elongation and wear. Inspect diaphragm 

rod for wear or marks. 

Clean or repair if appropriate. Replace as required. 

Step 2:

 

Reassembly: There are two different types 

of diaphragm plate assemblies utilized throughout the 

Sandpiper product line: Outer plate with a threaded 

stud, diaphragm, and a threaded inner plate. 

Outer plate with a threaded stud, diaphragm, and 

an inner plate with through hole. Secure threaded 

inner plate in a vise. Ensure that the plates are being 

installed with the outer radius against the diaphragm. 

Step 3:

 Lightly lubricate, with a compatible material, 

the inner faces of both outer and inner diaphragm plates 

when using on non Overlay diaphragms (For EPDM 

water is recommended). No lubrication is required. 

Step 4: 

Push the threaded outer diaphragm 

plate through the center hole of the diaphragm. 

Note: 

Most diaphragms are installed with the 

natural bulge out towards the fluid side.  S05, 

S07, and S10 non–metallic units are installed 

with the natural bulge in towards the air side.  

Step 5: 

Thread or place, outer plate stud into 

the inner plate. For threaded inner plates, use a 

torque wrench to tighten the assembly together.  

Torque values are called out on the exploded view. 

Repeat procedure for second side assembly. 

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 6:

 Thread one assembly onto the diaphragm 

rod with sealing washer (when used) and bumper. 

Step 7: 

Install diaphragm rod assembly 

into pump and secure by installing the outer 

chamber in place and tightening the capscrews. 

Step 8: 

On opposite side of pump, thread the 

remaining assembly onto the diaphragm rod. Using a 

torque wrench, tighten the assembly to the diaphragm 

rod. Align diaphragm through bolt holes, always going 

forward past the recommended torque. Torque values 

are called out on the exploded view. 

NEVER

 reverse 

to align holes, if alignment cannot be achieved 

without damage to diaphragm, loosen complete 

assemblies, rotate diaphragm and reassemble as 

described above. 

Step 9: 

Complete assembly of entire unit.

One Piece Diaphragm Servicing (Bonded PTFE 

with integral plate) The One Piece diaphragm has 

a threaded stud installed in the integral plate at the 

factory. The inner diaphragm plate has a through 

hole instead of a threaded hole. Place the inner 

plate over the diaphragm stud and thread the first 

diaphragm / inner plate onto the diaphragm rod only 

until the inner plate contacts the rod. Do not tighten. A 

small amount of grease may be applied between the 

inner plate and the diaphragm to facilitate assembly. 

Insert the diaphragm / rod assembly into the pump 

and install the outer chamber. Turn the pump over 

and thread the second diaphragm / inner plate onto 

the diaphragm rod. Turn the diaphragm until the 

inner plate contacts the rod and hand tighten the 

assembly. Continue tightening until the bolt holes 

align with the inner chamber holes. 

DO NOT LEAVE 

THE ASSEMBLY LOOSE.

Diaphragm  Servicing

IMPORTANT

Read these instructions completely, 

before installation 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.
