In this document you will find warnings and cautions for installation, use and maintenance of the pumps.
Here’s the meaning of symbols you may find in this document and general warnings that you should keep in mind.
WARNING: This symbol aware that there is a danger of serious bodily injury or death if you ignore the warning described.
CAUTION: This symbol aware that there is a danger of personal injury or property damage if you ignore the caution described.
• This equipment is for professional use only.
• Do not degrade the integrity of the equipment. Use only original
replacement components from ALENTEC & ORION AB
• Fluids not suitable for the pump can cause damage to the pump unit
and involve risk of serious personal injury. Always consult ALENTEC &
ORION AB if you have any questions about the compatibility within the
fluids and the pump materials, including elastomers.
• Install and use the pump according to all local and national regulations
and abide all health and safety laws or legislation.
• The pump can produce fluid pressures equal to the air supply pressure.
Do not exceed the maximum allowable pressure of 120 psi (8 bar) air
supply. The total hydraulic pressure (differential pressure + system)
should never exceed 120 psi (8 bar).
• Never use a pump that leaks, that is damaged, that is corroded or
otherwise it may lack the capacity to contain the fluid.
• Frequently check that the bolts on the diaphragm cover of the pump
are torqued correctly.
• Do not use a model with aluminium wetted surfaces to pump fluids for
human consumption, there is a possibility of trace contamination of lead.
• Danger of explosion if used 1,1,1-trichloroethane, methylene chloride
or other halogenated hydrocarbon solvents with aluminium wetted
materials. It could cause serious injury and property damage.
• Inside the pump, diaphragms separate the fluid that is being pumped
from the air supply. If a diaphragm breaks, the fluid can leak out of the
air exhaust and contaminate the environment.
• When handling hazardous fluids, always route the air exhaust into a
suitable container and locate it in a safe place. (Optional conection
system at customer’s request. Not supplied with the unit).
• When the fluid source level is situated higher than the pump, (flooded
suction), the outlet tank must be at a higher level than the product to prevent
spills.
• For pumps handling hazardous fluids that are a danger to humans or
to the environment, install a suitable container surrounding the pump
to prevent any leaks or spills.
• Ensure that the operators of this equipment are trained on the
operation and limitations. Use safety equipment as safety goggles or
other equipment required.
WARNING: CAREFULLY READ THE INSTRUCTIONS AND WARNINGS BEFORE OPERATING THE EQUIPMENT!
WARNINGS AND CAUTIONS
Air operated double diaphragm pumps are air-powered, reciprocating
positive displacement pumps with two pumping chambers. Two
diaphragms, centrally located in the chambers, separate the compressed
air (dry side) from the fluid being pumped (wet side). A shaft transmits the
reciprocating motion of one diaphragm to the other. A directional valve
alternatively distributes the air from one chamber to the other; thus a
reciprocating movement of the diaphragms is created. With each stroke,
fluid is discharged by one of the diaphragms whilst the opposite
diaphragm sucks new fluid into the expanding chamber. Check valves,
two on the discharge side and two on the suction side, control and direct
the fluid flow.

DESCRIPTION
• Remove the pump from its package and install it on the chosen location.
• Try to minimize the suction head. Install the pump as close as possible to the fluid being pumped.
• Remember to have enough space around the pump to perform maintenance tasks.
• Keep in mind to connect the inlet and outlet of the pump correctly.
• In case of diaphragm pump failure, the air exhaust will expel the product being pumped.
• When the pump is installed in a place where a spill of fluid can cause an environmental impact, the exhaust should be directed to a place.where
this spill could be contained.
• When installing the pump in its place, use brackets to secure its base.
• Fasten all bolts with the torques contained in this manual.

FLOODED:
The pumping system was designed with positive pressure at the inlet.
This is the best possible installation when you need to evacuate the liquid
from the drum or tank, or when working with viscous fluids.
Not recommended for hazardous fluids.
SELF-PRIMING:
Pump is designed to generate vacuum. It is possible to evacuate all the air
from a hose or pipe without damaging the pump. Maximum suction height
is (5 m) 16.5 ft, with the suction hose empty and up to 8 m (26.25 ft) with
the hose primed.
NOTE: Use a pressure regulator with built-in filter
inlet.
NOTE: The compressed air supply must be
between 1,5 bar (20 psi) and
8 bar (120 psi).

THIS PUMP IS SELF-PRIMING
To prime it the first time, you must connect the air pump supply to a low pressure using the pressure regulators while keeping the outlet valve open.
When fluid begins to flow from the pump outlet, the pump is primed. For regulation of fluid pressure, the unit must be supplied with an air pressure
between 1,5 and 8 bar (20 and 120 psi). Adjust the discharge valve on the discharge side to control flow. For the performance characteristics of the
pump see the capacity curve.
• Stop the air supply.
• Make sure for your safety that the air valve is closed.
• Close the discharge valve and the suction valve. Open inlet and outlet drain valves.
• Open the air valve of the pump, running bring on the pump and flushing the remaining fluid.
• Close the air valve.
• After ensuring that the pump was turned off and the pressure was released, pump is ready for its maintenance.
WARNING
Connect grounding wires to the pump, piping and all other
equipment too.
When the pump operates ungrounded or with an incorrect
connection, friction between parts and abrasion caused by some
fluids that flow inside the pump, can generate static electricity.
Moreover, according to the type of fluid pump and the installation
environment (such as gases in the air or the type of the
surrounding facilities) static electricity can cause fire or electric
shock.
When installing the pump, be sure to perform grounding in the specified
location.
Also connect ground wires for the auxiliary equipment and piping.
Use a grounding cable of at least 12 gauge (2.0 mm2).
If the pump you have purchased is valid for Atex, a specific Atex manual
will accompany this one. Read this manual before operating the pump.
If the unit is marked with the symbol , it can be used in potentially
explosive atmospheres. Below this symbol, in the nameplate of the pump,
are indicated the areas for which the equipment is approved. You will also
find the maximum allowable surface temperature in the same plate.

REPAIR AND MAINTENANCE PROCEDURES
For proper operation of the pump and to prevent accidents which may
damage equipment and in the worst case, people, you must periodically
review the torques of the diaphragms covers and the DIRECTIONAL
VALVE. In the next table are shown the appropriate torques for this
purpose:
TORQUES
DP200
Diaphragm cover 132 lbf·in ( 15 N·m)
Directional valve 70 lbf·in ( 8 N·m)
Manifolds 132 lbf·in (15 N·m)
TORQUES NECESSARY FOR THE PROPER FUNCTIONING OF THE PUMP
DIAPHRAGM MAINTENANCE
Before any intervention: DISCONNECT AIR SUPPLY OF THE PUMP.
IT IS NOT NECESSARY TO REMOVE THE PUMP FROM THE FLUID LINE.
REMOVING THE DIAPHRAGM:
1. Close inlet and discharge fluid valves.
2. Drain the fluid inside the pump.
3. Remove the directional valve while being careful not to damage the
seals between air valve and diaphagm.
4. Remove the diaphragm cover screws.
NOTE: To tighten these screws you must use a torque wrench
calibrated to (see torque table in this page).
5. Remove the cover by gently pulling back.
6. Remove the used diaphragms.
INSTALLING THE NEW DIAPHRAGMS - ASSEMBLING PROCEDURE
CAUTION: Follow next procedure to ensure the diaphragms are
correctly installed. If not followed diaphragm bead could be
extruded out of its housing with the resulting damage over the
diaphragm bead and thus possible fluid leaks or premature
diaphragm failure.
1. Correct assembly of the diaphragm
before the diaphragm cover assembly.
2. Incorrect assembly of the diaphragm.
Possible damage when assembling the
diaphragm cover.
Avoid instally the diaphragm without preparing the central rod in its proper position.
Diaphragm bead could be damaged when installing diaphragm cover.
1. PREPARING THE CENTRAL ROD FOR DIAPHRAGM INSTALLATION
Using a soft head hammer displace the central rod out of the body enough to install the
diaphragm without deforming it.
NOTE: Be careful to not lose the seals
between valve and diaphragm cover.
CAUTION!
SOFT HEAD
CAUTION!: DO NOT OVERTIGHTEN FASTENERS.
ANTICIPATE A POSSITE LEAKAGE OF FLUID INSIDE THE PUMP.

2. FIRST DIAPHRAGM ALIGNMENT
Using the soft head hammer, againg align the diaphragm bead until the bead touches
the housing without deformation.
The diaphragm bead touches
the housing without
deformation.
3. DIAPHRAGM COVER INSTALLATION
Place the diaphragm cover and approximate it using the bolts (follow the TIGHTENING
SEQUENCE).
Once approximated, torque @132 lbf·in (15 N·m).
CAUTION!: DP200 pump body is fitted
with two nipples that fit with two holes in
the diaphragm cover to ensure that the
cover is placed in its correct possition.
TIGHTENING SEQUENCE
5. SECOND DIAPHRAGM ALIGNMENT
Install the remaining diaphragm and again, using the soft head hammer, align the
diaphragm bead until the bead touches the housing without deformation.
6. SECOND DIAPHRAGM COVER INSTALLATION
Follow same procedure as for the first diaphramg cover described inpoint nº3.
4. CENTRAL ROD RELEASE FOR SECOND DIAPHRAGM ALIGNMENT
Using an air gun fed with 1bar (15psi) maximum air pressure, inject
air in the air chamber of the diaphragm cover trough the hole nº1
meanwhile closing the holes nº2 and nº3 . Compresed air will push
out the central rod allowing the diaphagm installation without
deformation.
When we hole nº1 is feed with compressed air while closing nº2 and nº3 air enters in the
chamber, displacing the central rod and allowing to install the diaphragm.

aluminum, stainless steel), use
additional o-rings for sealing. See
seat position in the drawing to
ensure correct assembly. The
bigger diameter o-ring is
assembled over the seat and the
smaller one below it.
Balls must be always assembled
over the seat.
CAUTION!
