1/ INTRODUCTION
1.1 - GENERAL
The air operated diaphragm pump series AD is manufactured by ALBIN PUMP and is marketed and sold by
a net of authorised distributors.
This instruction manual contains important information on the AD range and must be read carefully before
installation, service and maintenance. The manual must bekept easily accessible to the operator.
IMPORTANT !
The pump must not be used for other purposes than recommended and quoted for without consulting
the ALBIN PUMP distributor.
Liquids not suitable for the pump can cause damages to the pump unit and imply risk of serious
personal injury.
1.2 - RECEPTION AND STORAGE
1.2.1 - Reception
Remove all packing materials immediately after reception. Check the consignment for damage at once and
make sure that the name plate/type designation is in accordance with the packing slip and your order.
In case of damage and/or missing parts a report should be drawn up and presented to the carrier instantly.
Notify your ALBIN PUMP distributor.
All pumps have the type specication (Type) printed on the name plate which is located on the pump hous-
ing above the inlet port. This specication should always be quoted in all correspondence with your dis-
tributor.
The model specication (Type) describes the pump materials and options - see section 1.5
The manufacturing date (Mfg. date),
e.g. 090128 states year, month and day of
manufacturing.
The serial number (Mfg. No.) is a
consecutive number registered at Albin Pump.
The arrow on the name plate shows the ow
direction.
1.2.2 - Storage
If the pump is not installed immediately it is recommended to store it in a dry, clean and cool location.
The pump is tested with compressed air in a completely dry condition so there is no liquid left in the pump.

1.3 - SAFETY
IMPORTANT !
The pump must not be used for other purposes than recommended and quoted for without consult-
ing your ALBIN PUMP distributor.
Liquids not suitable for the pump can cause damages to the pump unit and imply risk of serious
personal injury. Always consult your ALBIN PUMP distributor if you are not sure of the compatibility of
uids with the pump materials including the elastomers.
HAZARD WARNING - POSSIBLE EXPLOSION HAZARD can result if 1, 1, 1-Trichloroethane, Methy-
lene Chloride or other Halogenated Hydrocarbon Solvents are used in pressurized uid systems hav-
ing Aluminium wetted parts. Death, serious bodily injury and/or property damage could result.
The pump must always be installed and used in accordance with existing local and national sanitary
and safety regulations and laws.
The pump can create uid pressures equal to the air supply pressure. Do not exceed the maximum
permissible air supply pressure of 7 bar. The total hydraulic pressure (system pressure + differential
pressure) must never exceed 7 bar.
Do not exceed the recommended operating temperatures of the pump. The maximum temperature
limitations are based on mechanical stress only and various liquids/chemicals may reduce the maxi-
mum safe operating temperatures of the pumps.
Diaphragms : PTFE can operate continuously between -30°C and +85ºC.
Pump housing : PP (polypropylene) can be used in the interval ±0°C and +85 ºC.
Aluminium can be used in the same interval as the diaphragms.
Inside the pump two diaphragms are separating the pumped liquid from the air supply.
When a diaphragm ruptures uid may be expelled through the air exhaust port. If dangerous liquids
are handled always connect the air exhaust port with a suitable container in a safe location. When the
product source is at a higher level than the pump (ooded suction), the exhaust should be piped to a
higher level than the product to prevent spills caused by siphoning.
Never operate a pump that is leaking, damaged, corroded or otherwise unable to contain the internal
uid or air pressure.
Never exceed the recommended service and inspection intervals for the diaphragms and air motor
parts.
Never put your face or body near the pump air exhaust while the pump is operating.
Always shut off the air supply and disconnect it from the pump before making repairs to the pump.
Be sure to relief all pressure from the discharge and suction pipes/hoses prior to disconnecting the
pump from the system.
Static electricity can be created when the pump is operating. Always use conductive polypropyl-
ene pumps in hazardous environments or for ammable uids. Pumps must be properly grounded.
Strictly follow the local safety regulations for hazardous environments.

IMPORTANT !
The pump must not be used for other purposes than recommended and quoted for without consult-
ing your AlLBIN PUMP distributor.
Never use, under no circumstances, the pumps for pumping non-conductive ammable or explosive
uids.
The AD pumps do not exceed a noise level rating of 80 dB(A) but still it is advised always to wear ear
protection when you are working or standing close to an operating AODD pump. Noise can be sub-
stantially reduced by leading the exhaust air away through a hose connected to the air exhaust port.
Always wear suitable safety clothing when handling the pump.
Install shut-off valves on both side of the pump to be able to shut off the in- and outlet before service
and maintenance. Check to see that the pump can be drained without injuring anyone and without
damaging the environment or nearby equipment.
Always install a separate shut-off valve for the air supply easily accessible for manoeuvring.
Pressure variations may cause vibrations in the piping systems. Connect the pump to the pipes via
flexible coupling/hoses. Ensure that the pipes/fittings are securely bolted to the foundation.
Improper installation can cause fatal injuries.
If the pump handles liquids hazardous for person or environment, some sort of collector must be in-
stalled into which leakage can be led.
If the surface temperature of the system or parts of the system exceeds 60°C, these areas must be
marked with warning text reading ‘‘Hot surface’’ to avoid burns.
Never use other compressed gases than air to operate the pump.
Before starting the pump always make sure that the discharge point of the piping system is clear and
safe and that all persons have been warned to stand clear.
Always check the flow direction prior to start-up.

1.4 - OPERATING PRINCIPLE
The AODD pump is an air-powered, reciprocating positive displacement pump with two pumping chambers.
Two diaphragms, centrally located in the chambers, separate the compressed air (‘‘dry side’’) from the liquid
being pumped (‘‘wet side’’). A shaft connects the two diaphragms to each other.
A valve (air motor) distributes the air from one chamber to the other alternately, thus a reciprocating move-
ment of the diaphragms is created. At each stroke liquid is displaced by one of the diaphragms while the
opposite diaphragm sucks new liquid into the expanding chamber. Check valves, two on the discharge side
and two on the suction side, control and direct the liquid ow.
1.4.1 - OPERATING PRINCIPLE FOR THE AD PUMP
Compressed air enters the air chamber (a) on the left side of the pump. The diaphragms are pushed to the
right and liquid is displaced from chamber (A). Simultaneously pressure is reduced in chamber (B) and new
liquid enters. Used air is pushed out from the right air chamber (b).
Note the short ow path through the centre of the pump and how the check valves are opening and closing.
In the AD pump the diaphragms are not xed to the shaft. Thanks to this Flexible Diaphragm Suspension
(FDS-invention) and the spring at the shaft end, the diaphragms can move a short distance independently
of each other. At the end of each stroke both diaphragms are exposed to compressed air for a very short
period. When the left diaphragm has come to the end position, the right one has already started to move
back to the left and the spring is compressed. Thereafter the left diaphragm starts to move to the left and
the spring expands.
The two diaphragms are overlapping each other and thus there is no complete dead end at the same mo-
ment - pulsation is reduced.
This operating principle requires an extremely short reversing time of the compressed air.
The traditional sliding air valve could not be used and a new low friction air motor (FPV-invention - Friction-
less Pivoting Valve) with a rocking motion was developed. The new air motor is nothing less than a patented
sensation - extremely simple with very few parts and completely insensitive to the quality of the compressed
air.
The cycle is completed and the two diaphragms are now moving back to the left.
