IMPORTANT

Read the safety warnings and instructions in this manual
before pump installation and start-up. Failure to comply with
the recommendations stated in this manual could damage the
pump and void factory warranty.

When used for toxic or aggressive uids, the pump should
always be ushed clean prior to disassembly.

Airborne particles and loud noise hazards. Wear eye and ear
protection.

Before maintenance or repair, shut off the compressed air line,
bleed the pressure, and disconnect the air line from the pump.

Be certain that approved eye protection and protective clothing
are worn at all times. Failure to follow these recommendations
may result in serious injury or death.

ATEX compliant pumps are suitable for use in explosive atmospheres when the equipment is properly grounded
in accordance with local electrical codes. Pumps equipped with electrically conductive diaphragms are suitable for

the transfer of conductive or non-conductive uids of any explosion group. When operating pumps equipped with
non-conductive diaphragms that exceed the maximum permissible projected area, as dened in EN 13463-1: 2009
section 6.7.5 table 9, the following protection methods must be applied:

• Equipment is always used to transfer electrically conductive uids or

• Explosive environment is prevented from entering the internal portions of the pump, i.e. dry running
For further guidance on ATEX applications, please consult the factory.

When the pump is used for materials that tend to settle out

or solidify, the pump should be ushed after each use to

prevent damage. In freezing temperatures the pump should be
completely drained between uses.

Before pump operation, inspect all fasteners for loosening

caused by gasket creep. Retighten loose fasteners to prevent
leakage. Follow recommended torques stated in this manual.

CAUTION

WARNING

Nonmetallic pumps and plastic components are not UV
stabilized. Ultraviolet radiation can damage these parts and
negatively affect material properties. Do not expose to UV light
for extended periods of time.

In the event of diaphragm rupture, pumped material may enter
the air end of the pump, and be discharged into the atmosphere.
If pumping a product that is hazardous or toxic, the air exhaust

must be piped to an appropriate area for safe containment.

This pump is pressurized internally with air pressure during
operation. Make certain that all fasteners are in good condition
and are reinstalled properly during reassembly.

Take action to prevent static sparking. Fire or explosion can

result, especially when handling ammable liquids. The pump,
piping, valves, containers and other miscellaneous equipment

must be properly grounded.

Use safe practices when lifting

kg

RECYCLING

Many components of SANDPIPER® AODD

pumps are made of recyclable materials.

We encourage pump users to recycle worn

out parts and pumps whenever possible,
after any hazardous pumped fluids are

thoroughly ushed.

WARNING
The use of non-OEM replacement parts will void (or negate)

agency certications, including CE, ATEX, CSA, 3A and EC1935
compliance (Food Contact Materials). Warren Rupp, Inc. cannot

ensure nor warrant non-OEM parts to meet the stringent
requirements of the certifying agencies.

5 • Model HDB2/HDB50

hdb2dl3sm-rev0817

Air-Operated Double Diaphragm (AODD) pumps are powered

by compressed air or nitrogen.

The main directional (air) control valve

①

distributes
compressed air to an air chamber, exerting uniform pressure
over the inner surface of the diaphragm

②

. At the same time,

the exhausting air

③

from behind the opposite diaphragm
is directed through the air valve assembly(s) to an exhaust
port

④

.

As inner chamber pressure

(P1) exceeds liquid chamber

pressure

(P2), the rod

⑤

connected diaphragms shift
together creating discharge on one side and suction on the
opposite side. The discharged and primed liquid’s directions

are controlled by the check valves (ball or ap)

⑥

orientation.

The pump primes as a result of the suction stroke. The
suction stroke lowers the chamber pressure

(P3) increasing

the chamber volume. This results in a pressure differential
necessary for atmospheric pressure

(P4) to push the uid

through the suction piping and across the suction side check
valve and into the outer uid chamber

⑦

.

Suction (side) stroking also initiates the reciprocating
(shifting, stroking or cycling) action of the pump. The suction

diaphragm’s movement is mechanically pulled through its

stroke. The diaphragm’s inner plate makes contact with an

actuator plunger aligned to shift the pilot signaling valve.
Once actuated, the pilot valve sends a pressure signal to the
opposite end of the main directional air valve, redirecting the
compressed air to the opposite inner chamber.

hdb2dl3sm-rev0817

Installation And Start-Up

Locate the pump as close to the product being pumped as possible. Keep the suction line length and number of ttings to a minimum. Do not reduce the suction line

diameter.
Air Supply

Connect the pump air inlet to an air supply with sufcient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to

insure air supply pressure does not exceed recommended limits.
Air Valve Lubrication

The air distribution system is designed to operate WITHOUT lubrication. This is the standard mode of operation. If lubrication is desired, install an air line lubricator
set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9.4 liters/sec.) of air the pump consumes. Consult the Performance Curve to determine air

consumption.
Air Line Moisture

Water in the compressed air supply may cause icing or freezing of the exhaust air, causing the pump to cycle erratically or stop operating. Water in the air supply can

be reduced by using a point-of-use air dryer.
Air Inlet And Priming

To start the pump, slightly open the air shut-off valve. After the pump primes, the air valve can be opened to increase air ow as desired. If opening the valve
increases cycling rate, but does not increase the rate of ow, cavitation has occurred. The valve should be closed slightly to obtain the most efcient air ow to pump
ow ratio.

Troubleshooting Guide

For additional troubleshooting tips contact After Sales Support at [e-mail] or 419-524-8388

Symptom: Potential Cause(s): Recommendation(s):

Pump Cycles Once

Deadhead (system pressure meets or exceeds air
supply pressure).

Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.
(Does not apply to high pressure 2:1 units).

Air valve or intermediate gaskets installed incorrectly. Install gaskets with holes properly aligned.

Bent or missing actuator plunger. Remove pilot valve and inspect actuator plungers.

Pump Will Not Operate
/ Cycle

Pump is over lubricated. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation.

Lack of air (line size, PSI, CFM). Check the air line size and length, compressor capacity (HP vs. cfm required).

Check air distribution system. Disassemble and inspect main air distribution valve, pilot valve and pilot valve actuators.

Discharge line is blocked or clogged manifolds. Check for inadvertently closed discharge line valves. Clean discharge manifolds/piping.

Deadhead (system pressure meets or exceeds air
supply pressure).

Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.
(Does not apply to high pressure 2:1 units).

Blocked air exhaust mufer. Remove mufer screen, clean or de-ice, and re-install.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.

Pump chamber is blocked. Disassemble and inspect wetted chambers. Remove or ush any obstructions.

Pump Cycles and Will
Not Prime or No Flow

Cavitation on suction side. Check suction condition (move pump closer to product).

Check valve obstructed. Valve ball(s) not seating
properly or sticking.

Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.
Clean out around valve ball cage and valve seat area. Replace valve ball or valve seat if damaged.

Use heavier valve ball material.

Valve ball(s) missing (pushed into chamber or
manifold).

Worn valve ball or valve seat. Worn ngers in valve ball cage (replace part). Check Chemical
Resistance Guide for compatibility.

Valve ball(s) / seat(s) damaged or attacked by product. Check Chemical Resistance Guide for compatibility.

Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.

Suction line is blocked. Remove or ush obstruction. Check and clear all suction screens or strainers.
Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.

Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.

Pump Cycles Running
Sluggish / Stalling,

Flow Unsatisfactory

Over lubrication. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation.

Icing. Remove mufer screen, de-ice, and re-install. Install a point of use air drier.
Clogged manifolds. Clean manifolds to allow proper air ow.

Deadhead (system pressure meets or exceeds air
supply pressure).

Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.
(Does not apply to high pressure 2:1 units).

Cavitation on suction side. Check suction (move pump closer to product).

Lack of air (line size, PSI, CFM). Check the air line size, length, compressor capacity.

Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.
Air supply pressure or volume exceeds system hd. Decrease inlet air (press. and vol.) to the pump. Pump is cavitating the uid by fast cycling.
Undersized suction line. Meet or exceed pump connections.

Restrictive or undersized air line. Install a larger air line and connection.

Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.

Suction line is blocked. Remove or ush obstruction. Check and clear all suction screens or strainers.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.

Check valve obstructed. Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.

Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.
Entrained air or vapor lock in chamber(s). Purge chambers through tapped chamber vent plugs. Purging the chambers of air can be dangerous.

Product Leaking
Through Exhaust

Diaphragm failure, or diaphragm plates loose. Replace diaphragms, check for damage and ensure diaphragm plates are tight.

Diaphragm stretched around center hole or bolt holes. Check for excessive inlet pressure or air pressure. Consult Chemical Resistance Chart for compatibility

with products, cleaners, temperature limitations and lubrication.

Premature Diaphragm
Failure

Cavitation. Enlarge pipe diameter on suction side of pump.

Excessive ooded suction pressure. Move pump closer to product. Raise pump/place pump on top of tank to reduce inlet pressure.

Install Back pressure device (Tech bulletin 41r). Add accumulation tank or pulsation dampener.

Misapplication (chemical/physical incompatibility). Consult Chemical Resistance Chart for compatibility with products, cleaners, temperature limitations

and lubrication.

Incorrect diaphragm plates or plates on backwards,

installed incorrectly or worn.

Check Operating Manual to check for correct part and installation. Ensure outer plates have not been

worn to a sharp edge.

Unbalanced Cycling

Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.
Undersized suction line. Meet or exceed pump connections.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.

Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.

Check valve obstructed. Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.

Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.
Entrained air or vapor lock in chamber(s). Purge chambers through tapped chamber vent plugs.

Model HDB2/HDB50 • 13

hdb2dl3sm-rev0817

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. T orque 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 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.
