Warnings and cautions
In this document you will find warnings and cautions for installation, use
and maintenance of the Direcflo pumps.
This symbol aware that there is a danger of serious bodily injury or death
if you ignore the warning described.
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 Samoa Industrial, S.A.
• Fluids not suitable for the pump can cause damage to the pump unit
and involve risk of serious personal injury.
• Always consult Samoa Industrial, S.A. 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 115 psi (8 bar) air
supply. The total hydraulic pressure (differential pressure + system)
should never exceed 115 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.
Warning Caution
• 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.
• 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.
Carefully read the instructions and warnings before operating the equipment!
Warning
Here’s the meaning of symbols you may find in this document and
general warnings that you should keep in mind.
Description
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.

Installation
Installation recommendations
• 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 expell 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.
DF pumps are very easily configured and easy to install.
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 19.69 ft (6 m), with the suction hose empty and up to 26.25 ft
(8 m) with the hose primed. (See page 1 for corresponds suction lift).
Submerged:
All pumps can be immersed in fluids. It is important to verify that all
components that are in contact with the fluid are chemically compatible.
In this case, air exhaust and fluid must be carried by hoses (optional air
connection).
Recommended installation
The figure below shows the recommended
configuration for the installation of a
diaphragm pump.
Read the warnings and recommendations of
the previous page before starting.
NOTE: Use a pressure regulator with built-in
filter inlet.
NOTE: The compressed air supply must be
between 43.5 psi (3 bar) and 115 psi (8 bar).
Air exhaust disposal
• Optional kit is required for remote exhaust.
• Remove the muffler.
• Connect a hose to the exhaust port of the pump and install the muffler
at the end of the hose. Use a hose with the same diameter as the
exhaust port. (If the hose is more than 5 feet (1.5 m), consult your
dealer or Samoa Industrial, S.A.).
• Have a moat, a protective housing, etc. at the end of the hose.
The pump exhaust should be directed to a safe place, away from people,
animals and food.

Operating instructions
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
Installation
Warning
Air connection
To ensure that the air supply is sufficient to meet the demand of the
pump, the diameter of the pipe must be equal to the diameter of the
supply port of the pump. Choose auxiliary air treatment equipment and
fittings with sufficient airflow to exceed the air consumption of the pump.
In addition, peripheral air treatment equipment must be installed as close
as possible to the pump unit.
The use of a coupler to connect the hoses aids future operation and
maintenance tasks.
regulation of fluid pressure, the unit must be supplied with an air
pressure between 43.5 and 115 psi (3 and 8 bar). Adjust the discharge
valve on the discharge side to control flow. For the performance
characteristics of the pump see the capacity curve shown on page 3.
Stopping the pump
• Close the inlet valve of the pump and stop the air supply.
• Make sure for your safety that the air valve is closed.
• Turn off the air compressor, or close the valve on the air supply side of
the auxiliary equipment.
• Close the discharge valve on the discharge side, then begin to slowly
open the drain valve and discharge pressure fluid.
• Open the air valve of the pump, turn on the pump and flush the
remaining fluid.
• After ensuring that the pump was turned off and the pressure was released,
fully open and close the regulator valve and drain valve of the pump.
Grounding the pump
• 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).
STICKER THAT SHOWS
THE POSITION OF THE
GROUND WIRE
• 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.
Warning
• 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
Torques necessary for the proper functioning of the pump
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 DF50
Diaphragm cover 48.67 - 53.1 lbf·in (5,5 - 6 N·m)
Directional valve 44.25 lbf·in (5N·m)
Valve cap 35.4 lbf·in (4 N·m) Aluminium - 30.9 lbf·in (2 N·m) composite
Diaphragm replacement
Torques DF30
Diaphragm cover 70.81 lbf·in (8 N·m)
Directional valve 44.25 lbf·in (5 N·m)
Valve cap 30.9 lbf·in (2 N·m) composite
Torques DF100
Diaphragm cover 137.7 lbf·in (15 N·m)
Directional valve 44.25 lbf·in (5 N·m)
Valve cap 35.4 lbf·in (4 N·m) Aluminium - 30.9 lbf·in (2 N·m) composite
Before any intervention: DISCONNECT AIR SUPPLY OF THE PUMP.
IT IS NOT NECESSARY TO REMOVE THE PUMP FROM THE FLUID LINE.
1. Close fluid valves.
2. Drain the fluid inside the pump. Anticipate a drainage of fluid from inside
the pump.
3. Remove the directional valve while being careful not to damage the
seals shown in the figure.
4. Remove the diaphragm cap.
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 diaphragm and place the new one in the proper
position.
Assemble components.

Repair and maintenance procedures
Ball valves replacement
1. Close fluid valves.
2. Drain the fluid from inside the pump.
Anticipate a drainage of fluid from inside
the pump.
3. Loosen the screws to remove the directional
valve. Take special care with the seals.
4. Remove the valve cover by loosening the
screws with an Allen wrench. Take note of
the orientation of the cap, as it is critical to
replace it correctly during reassembly.
5. Install a new set of valves according to
these assembly drawings. Ensure that the
ball guides are assembled as shown in the
figure on the left, and tighten the screws
with a maximum torque (see torque table
page 18).
6. Assemble the directional valve with
being careful not to damage the O-rings
and tighten the screws with a maximum
torque of 44.25 lbf·in (5 N·m).
To avoid fluid restriction and leakages, follow
the position of the ball checks guides in the
figure above. the valves cups must be placed
with the area indicated in the figure below
facing the body.
Attention
Air sensor (only for models with directional valve)
The air sensors are on the inside part of the diaphragm covers. To access
them, follow the procedure for “Replacing diaphragms".
Once removed the covers following procedure:
1. Remove the two screws that secure the air sensor to the top.
2. Remove all components of the sensor. Clean the area.
3. Introduce new components in the order shown.
4. Fit the cover on the pump and tighten the screws to the body of the
pump. Maximum tightening torque (see torque table page 18).
Fit the remaining components in reverse order.
