The rst condition of innovation is to question.
And the rst condition of sustainable innovation is to question
constantly.
The journey of innovation has started with a question for us too: “How can we develop value-
added technologies in Turkey?”. First turning point in this long journey was the birth of MIT (Made
in Turkey) brand. MIT made us the rst plate heat exchanger producer of Turkey and it’s founding
vision was not to become a local alternative, it was to build a high-quality brand that can compete
on a global level.
While we are working towards this goal in the past 15 years, our products and processes deemed
worthy for documentation by many national and international quality assessment institutions such
as ISO, TSE, CE, GOST and many more. This was the natural outcome of our constant questioning
of the status-quo and our desire to outperform ourselves.
New Generation Engineering
With our engineering approach that focuses on the process, not the problem, we do not just
specialize in a product, we consider the entire ecosystem of that product. Ergo, we produce
all the other components of a system in addition to plate heat exchangers and we focus on the
constant development of engineering staff required to provide an end-to-end application.
We provide a “solution” rather than a product with our business development, presales, sales and
after sales services provided by our expert engineers.
In our 15th year, we continue to grow as a solution partner for projects that need high technology
in more than 60 countries with our internationally approved high-quality plate heat exchangers;
components such as accumulation tanks, boilers, industrial pumps and installation materials that
completes these exchangers to form a system; and complementary services provided by our
expert engineer staff.

SAFETY
Equipment Misuse Hazard
• Fluid to be transferred by the diaphragm pump is notied to authorized dealer or main dealer.
The dealer determines pump that is compatible for uid. Consult to Ekin Endüstriyel before
pumping any other uid than notied uid transfer. 444 35 46 (EKIN)
• Working pressure of the diaphragm pump is (max.) 7 bars. These pressure values should not
be exceeded. Otherwise, diaphragm pump may be damaged or is not included within the
scope of warranty.
• Use noise preventive ear plugs, protection goggles and gloves while installing the diaphragm
pump for the rst time or is put into use and as long as it continues to operate.
• While diaphragm pump is in operation and under pressure, do not lift the pump.
• Comply with necessary re instructions and electricity and security instructions. (Local,
National and Regional)
• Do not make any alteration on parts of the diaphragm pump. Use always (OEM) original spare
parts.
• If you used exible hose while installing the diaphragm pump, pay attention not to bend this
hose during transfer.
• Hose in suction part should not be exible during or after installing the diaphragm pump.
Flexible hoses may be bended during suction and stop suction.
• Fluid to be transferred by the pump and pump body and elastomer (parts manufactured from
rubber) materials should be compatible. If you do not sufcient information whether they are
compatible or not, consult to Ekin Endüstriyel. 444 35 46 (EKIN)
The User’s Manual booklet includes user and instructions and you should absolutely
read it before using diaphragm pump. Manufacturer company does not accept any
responsibility regarding damage of the pump due to improper use.
It is proposed that Ekin Endüstriyel service makes the entire service and maintenance
of the pump. 444 35 46 (EKIN)
The User’s Manual should be considered as an integral part of the pump and you should
keep it around you to apply whenever you want.
Manufacturer company does not accept any responsibility regarding damage of the
pump due to improper use.
Manufacturer can change product characteristics, technical dimensions and informations and diagrams without
notice. Any information provided on this page may not be copied or used without the permission of the manufacturer.
The manufacturer cannot be held responsible for technical information and diagrams.

Toxic Fluid Hazard
• If the company producing uid for uid to be transferred with the diaphragm pump has any
warning, please consider these warnings.
• Control diaphragm pump body, its diaphragms and other equipment each day. If any wear and
tear is observed, immediately replace the part. When the diaphragm pump stops to operate
and removed from line, if there is risk that uid in it freezes, clean inside with a uid compatible
with this uid. Otherwise, material freezing in the diaphragm pump may damage the body and
diaphragms.
• Do not transfer trichloroethane, methylene chloride, other halogen hydrocarbon solvents or
uids containing such solvents in aluminum equipment that operate under pressure with these
pumps. Use of these uids may cause chemical reaction and their explosion possibility is high.
• Compliance of uid to be transferred with pump body and elastomer parts should be determined
while selecting diaphragm pump. Under improper situations, pump may be damaged, even
there may be injury and death risk. If uid to be transferred and pump body is improper, the
manufacturer company is not responsible for all the damages that may occur in case Ekin
Endüstriyel did not make this selection.
• Make diaphragm pump connections at original inlet and outlet size. When inlet and outlet
sizes are changed or are made smaller, the pump may be damaged and some parts
become deformed. In case of this situation, the manufacturer company is not responsible for
malfunctions and part losses in the pump and pump malfunctions shall not be included within
the scope of warranty.
If toxic uid or fume contacts with eyes or any part of the body during transfer, there may
be permanent damages and may cause death risk.
• You should know features of the uid to be transferred with the diaphragm pump. Take
precautions preventing contact of toxic or harmful uid with environment in parallel with this
information.
• Do not move, remove and remove when the diaphragm pump is under pressure in dangerous
and toxic uid transfers.
• Keep dangerous uid in approved container that uid will not damage.
• Approach uid transferred next to diaphragm pump in toxic and dangerous uid transfers with
compatible protective apron, clothes, gloves, goggles and mask.
• Notify absolutely that pumps sent to Ekin Endüstriyel and authorized dealer for repair make
toxic or dangerous uid transfer.
• Relieve exhaust air (pressure outlet) of the pumps making toxic uid transfer to areas that will
not damage anything. When diaphragms are exploded, toxic uid or gas in the pump shall be
taken out from pressure outlet.
• Make pipe connections of the pump to which dangerous uid shall be transferred in a controlled
manner.
• Clean these uids with the uids that can clean them before transferring toxic, acidic and
explosive uids beforehand and empty uid in the pump.
• These marks were attached on them while dispatching the pump.

3
• The pumps transferring inammable and ammable uids should be grounded against static
electricity (see page 4, gure 1).
• Do not transfer non-conductor inammable uids with non-conductor pump body materials
(polypropylene, PVDF).
• If you encounter any electric shock or sparks while using the pump and equipment, stop the
pump. Do not operate the pump without being sure that problem was resolved.
• If uid transfer is made to the diaphragm pump and it is in a closed environment, ventilate the
environment.
• Carry air outlet to a secure environment with pipe. In case of diaphragm explosion, since
ammable material will move out with pressurized air, some accidents will be prevented (see
page 7, gure 3).
• Do not smoke in an area where pump is installed and do not use lighter, do not weld .
• The pipe, connected to suction line during inammable and explosive uid transfer in
diaphragm pump, should not be exible. Otherwise, vacuum created by the diaphragm pump
during suction may cause that pipe bends and it may also stop uid suction. Besides, there
may be tears in the pipe whose surfaces stick together due to vacuum. These tears may cause
that inammable and explosive uid leaks outside.
• Use protective clothes, protective goggles and face mask in installation or repair of the pump
making inammable and explosive uid transfer.
• Take necessary safety precautions when inammable and explosive uid transfer will be made
with the diaphragm pump or transfer uid temperature is 80°C and above.
Installation in non-ventilated environments and proper grounding of the pumps that
are used in transfer of uids having re and explosion danger may cause dangerous
situations. In this case, there may be serious injuries or even deaths.
Fire and Explosion Hazard
The pump is delivered to user without equipment. The user is obliged to supply protective
equipment and transfer equipment.
Internal parts of the pumps sent to the manufacturer company or authorized dealer for service should be emptied
in a way not to damage environment and package. The manufacturer or authorized dealer should be notied about
uid when pumps via which dangerous, explosive, and inammable uid hazardous on human health is transferred.
The company using pump is responsible for injuries and even deaths that may occur.

INSTALLATION
General Information
Installation of the diaphragm pump is easy. However, if installation characteristics recommended
by the manufacturer company are considered, working life of the pump shall be long and have
high efciency. (see page 4, gure 1). It should be paid attention that there is no leak and ow
from thread connections when air or uid connection components (hoses, pipes, ttings material
and etc.) are interconnected while installing the diaphragm pump. All connection components
should be pressurized well. If necessary, uid seal should be used.
• All bolt and nut connections should be controlled before installing the diaphragm pump and
it necessary it should be re-tightened. There may be loosening in these connections due to
vibrations that the pump suffered during carrying.
• If there is pressure difference more than 25% between air pressure entering in the diaphragm
pump and outgoing uid pressure, the pump operates inefciently. Transferred uid is very
dense. This situation may be prevented by increasing weights of balls used as check valve or
by using stainless steel marbles.
• Rubber wedge should be placed under pump stands in a place where installation is made
while installing the diaphragm pump. This is recommended by the manufacturer company.
Rubber wedge decreases tensions to pump, prevents dissolution of bolts from vibration and
also prevents material fatigue.
• Diaphragm pump installation should be made to uid to be transferred at a close distance as
far as possible.
• Suction line length and ttings number should be kept at a minimum during installation.
• Diameter of suction line of the installed pump should not be decreased to smaller diameters.
• If pipe line is not exible in a place where diaphragm pump was installed, exible hose should
be positioned between pipe line and pump.

Temperature values of materials whose operation temperatures are given above are stated by considering use
conditions of the diaphragm pump.
Pressure from the air line connected to the pump should not exceed 7 bar. Install the air line with a
pipe that will not have less size than the connection size so that the pump operates at demanded
efciency. Air line connection size is 1/4 in MIT 160 type pump. Install air line of the pump as
shown in page 4, gure 1. Pay attention that air line between the master air line and pump is
exible. Place a cut-off valve (ball valve) before the air line coming to the pump. Close air inlet
from this valve when necessary or if pump air is cut off.

6
• Make air line connection as shown in page 4, gure 1. Connect accessories to the wall or to a
xed place. Make sure that air line conducts electricity.
• Place conditioner (air regulator) before air line of the diaphragm pump. Water in pressurized
air line may cause frosting or outlet air freezing. This may cause that pump operates in an
unbalanced way or it stops completely. Moisture and water in the pressurized air from the
compressor may be decreased by being used with water retainer that may be used in addition
to air drying unit of user. This will prevent that polluted air enters in this pump. Besides, it will
decrease or prevent freezing in outlet line by keeping a sum of water within line.
• Open air valve approximately between 1/2” and 3/4” to operate the pump. After the pump
operates, air ow may be given to air valve at demanded degree. If valve opening increases
change frequency but does not increase ow speed, it means that uid formed a cavitation
within suction line. In this case, air coming to valve is decreased and the pump is activated
slowly. Thus, cavitation is prevented.
• Fluid ow in the diaphragm pump is controlled in two ways either by controlling pressurized air
line entering in the pump with a pressure regulator, ball valve or solenoid valve or by controlling
uid outlet line of the pump with a pressure regulator, ball valve or solenoid valve.
Suction Line
Connection of the pump to master suction line after suction nozzle should be made with exible
hoses. This situation prevents that some parts of the pump are broken during knocking and that
bolts are loosened.
• Place cut-off valve before the suction line during installation of the pump. The valve shall
provide that pump is removed easily at repair and maintenance times.
• You can observe whether there is regular uid ow in section line of the pump or not via
manometer placed on the line.
• Flexible and master line pipes to be connected to suction line should be conductive. Ground
the pipes if you did not use conductive pipes.
• Diaphragm life becomes shorter in uid inlet pressure higher than 1 bar. The most distinct
characteristic of this is that diaphragm life of the diaphragm pumps connected under high
tonnage tanks is short due to tank pressure.
• The suction is from the bottom by construction in top check valve diaphragm pumps.
• Compression line should be connected to master line with a exible hose just like suction line
so that pipes in the pump are not exposed to knocking, bolts are not dissolved and pump parts
are not damaged.
• Place ball cut-off valve before the compression line in a way to be close to the pump (see
gure 1).
• Place manometer before the compression line to be able to read the pressure (see gure 1).
• Flexible and master line pipes to be connected to suction line should be conductive. Ground
the pipes if you did not use conductive pipes (see gure 1).
Air pressurized between air line connected to the diaphragm pump (shown with 3 in
gure 1) should be relieved. Otherwise, pressurized air provides that the pump acts in
an unexpected way. This situation may cause accidents and intoxications due to moving
parts.

7
Environment should be ventilated properly
according to system installation type. If the uid
transferred by the pump is toxic, inammable
or explosive, air outlet should be kept off from
human, other creatures, areas where food
manufacturing is made and all inammable
environments.
• Excessive limit of the air outlet causes
ineffective and unbalanced operation of the
pump.
• Installation should be made in a way
to gather air outlet in a container by
considering diaphragm explosion. You can
see this in gure 3.
Expansion of the uid in compression line by getting heated causes increase of pressure within
the line. This situation can be observed in long compression lines with sun effect or environmental
factors. Besides, this may occur when valves do not perform their duties in high pressure pumps
supported with the diaphragm pump. In these cases, it is recommended to set up pressure relief
mechanism as it is seen in page 7, gure 2 (by-pass line).

Do not tighten connection parts with excessive specied torque during installation. This situation may damage the
pump.
It is recommended to use pressure relief valve in systems where pressure is used in the highest way. This by-pass
system will prevent excessive increase of pressure or hose breakdown.
• Place uid relieve valve or valve to be able
to relieve pressure on the compression line.
• This valve prevents that harmful uids are
splashed to eyes or skin during relieve of
uid.
• It prevents serious injuries. These injuries
may cause death.

Ground the diaphragm pump as shown below (page 8, gure 4). Surfaces that contact with uid
in the diaphragm pump should be grounded with metal stainless wire or power cable. Suction
and compression lines should be selected from the conductive materials while transferring
inammable and explosive uids. Grounding should be made just like in the pump in two lines. Do
not use nonconductive polypropylene and PVDF bodies in inammable and explosive uid
transfer. All equipment should be grounded to prevent sparks and res that may occur due to
static electricity and to decrease risks (pump, air and uid hoses, air compressor, inammable
matter buckets, uid supply container and etc.).
• Clips should be also grounded in clip type pumps.
• Fluid pressures should be less than 2x1012 ohm centimeters in the diaphragm pumps.

Washing and Cleaning The Pump
The diaphragm pump to be installed was exposed to pressure and leakage test with water by the
Ekin Endüstriyel. If any food product will be transferred with this pump or any uid transfer to
react will be made in case of contact with water, wash the pump with a compatible solvent or
compatible uid before commissioning the pump.
Diaphragm pump should be grounded against the static electricity.
Grounding cable section should be minimum 6,5 mm in exproof pumps. Besides, HFFR (Halogen free ame
retardant) cable should be used instead of standard cable. Place to which cable to be used in the pump will be
connected was stated with a special mark on the pump. The customer supplies this cable.
Commissioning of The Pump
Connection of the diaphragm pump is very easy. The uid is absorbed inside the pump from the
bottom inlet pipe having suction nozzle and transfer uid is pressed to outside from the pump
from top outlet pipe having pressure nozzle. Diaphragm pumps have a knocking ow. One of the
ways to prevent knocking ow is to install exible hose before inlet and outlet line of the pump in
installation place. Another ow regulation is to place damping volume (balance tank, tranquilizer)
before the compression line.
Figure 4

Discharging Of Pressurized Equipment
The pump and equipment are under pressure until pressure in the pump is relieved. While the
pump is at this stage, the user may be damaged from material to be sprayed, poured or splashed
accidentally from the pump or equipment. Apply pressure relief procedure to decrease damage
and risks that may be occurred.
Situations when pressure relief procedure is applied:
• When you should relief pressure.
• When you stop the pump.
• When you control, clean or maintain any system equipment.
Manometer and valves are placed to inlet and outlet line to determine pressure values that
may occur in inlet and outlet of the pump and to be able to make ow adjustments. When one
valve or both valves are closed, the pump does not operate. When both valves are opened, the
diaphragm pump continues to operate. The diaphragm pump is not damaged in the meantime.
Pressurized air is needed so that diaphragm pump operates. Air inlet hose should have the same
diameter with air inlet line so that the pump operated with full capacity. It is recommended by
the manufacturer company to place conditioner before the air inlet line. The conditioner controls
pressure adjustments and lubricates air diverter valve. Fluid ow rate is adjusted by controlling
air ow with valve to be placed before the air inlet line.
Subjects to be considered while installing the diaphragm pump;
• The diaphragm pump should be close to uid to be transferred as much as possible.
• Suction line length and elbow number in the suction line should be kept minimum as much as
possible.
• Inlet - outlet dimension of the diaphragm pump should not be different from connection size in
a place where installation was made.
• Pipe connections should be made exible in a place where the diaphragm pump was installed.
• If the pump does not pull when it is operated, it means cavitation occurred.
• Cavitation causes that diaphragm life becomes shorter. Control suction height.
• Do not operate the pump fast, control suction line diameter. They may cause cavitation.
• Control all threaded connections and air connections against leakage and leaks during rst
commissioning of the pump. If there is any leak, its entering in inammable, explosive or acidic
uid environment may constitute risk.
• Damping tanks should be used to prevent knocking in the pipe line in long push distances.

How Should It Be Made?
• Close the air line entering in the pump from the valve. Open air pressure relief valve for relieving
pressure air remaining between air line valve and pump.
• Close the valve in the push line. Open the valve by opening a compatible container under uid
pressure relief valve. Empty remaining uid in the container. Remove outlet hose from the pump.
How Is The Fluid Remaining In The Pump Drained?
• Wear clothes compatible for uid transferred by the pump.
• Close valve, if any, in suction part of the pump.
• Use a compatible container to keep the uid that will ow or drop from the suction hose.
• Remove the suction hose from suction nozzle. Remove it if it is connected to ground (see page
10, gure 5).
