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.

Step 1: With the unit removed from service. Remove

each bottom boss plug (item 51). Drain the uid from

spill containment chambers. 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 uid 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 torqueing, and 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

reassemble containment chamber then the pumping

diaphragms (item 45) secure by installing the outer

chamber in place and tightening the capscrews.

Replace bottom boss plug (item 51) and O-Ring

(item 48) NOTE: The spill containment option has

two additional pumping diaphragms (item 45). These

diaphragms are installed with the natural concave

curve toward the outer chamber.

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: Reassemble containment chamber then the

pumping diaphragms (item 45) secure by installing the

outer chamber in place and tightening the capscrews.

Replace bottom boss plug (item 51) and new O-Ring

(item 48).

NOTE: The spill containment option has two

additional virgin pumping diaphragms (item 45). PTFE

diaphragms are installed with the natural concave

curve toward the outer chamber.

NOTE: 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 rst

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.

FILLING CHAMBERS WITH LIQUID

THE CHAMBERS ARE FILLED WITH WATER AT

THE FACTORY.

If you prefer to substitute another liquid, to prevent

system contamination consult the factory rst to

determine compatibility of the substitute with pump

construction.

Spill Containment Servicing

Follow the steps listed here to replace the liquid in the

pump after disassembly or liquid loss:

10. With the top two boss plugs (items 50) removed.

The spill containment chambers are lled through the

exposed ports.

11. Install safety clip (item 1-K) into the smaller

unthreaded hole in one end cap (item 1-E). This locks

the valve spool to one side, keeping the pump from

shifting. Apply air pressure to the air distribution valve.

12 Face the side of the pump with the installed safety

clip. If the safety clip is installed in the top end cap, ll

the left spill containment chamber. If the safety clip

is installed on the bottom end cap, ll the right spill

containment chamber. The volume of uid is 1198 ml

(40.49 . oz.). It is important that the exact amount

of uid is used. Too little or too much uid causes

premature diaphragm failure and erratic pumping.

13. Loosely reinstall one boss plug (item 50) to the

lled spill containment chamber.

14. Shut off air supply. Remove safety clip. Manually

shift air valve by pushing stroke indicator pin in the

opposite direction of current position. Install safety

clip (item 1-K) into the smaller unthreaded hole in the

opposite end cap (item 1-E). This locks the valve spool

to one side, keeping the pump from shifting. Adjust

the airline regulator so that air pressure slowly lls the

pump. The diaphragm expands, forcing the uid in the

chamber to be slowly displaced.

15. Loosen the top boss plug on the lled chambers.

This allows uid in the chamber to purge trapped air

from the chamber. This can be seen by watching the

column of uid in the sight tube. When uid appears at

the top of the port, quickly tighten the boss plug. Fluid

loss of 1 to 2ml is acceptable.

16. Tilt the pump so the uppermost pipe tee (item 52) is

in the vertical position. Loosen the pipe plug (item 49).

This will allow trapped air to purge through the pipe tee.

When uid appears at the tee opening, reinstall the pipe

plug. NOTE: If all air is not purged using this procedure,

remove the check valve components from the top

port of the outer chamber (item 44). Apply manual

pressure to the pumping diaphragm by inserting a blunt

instrument into the top port of the outer chamber and

applying pressure to the diaphragm. Loosen the pipe

plug (item 49) allowing the uid to purge any remaining

trapped air. Reinstall the plug.

17. Repeat steps 12 through 16 to ll opposite spill

containment chamber.

18. Reinstall the check valve components, discharge

manifold and elbows to the pump. The pump is now

ready for operation.
