3.INSTALLATION
3.1.Flushing The Pump
The pump was tested with diesel. If diesel may
contaminate the liquid which will pass through
the pump or if the diesel may react with the
liquid, then flush the pump with the appropriate
solvent completely. Read the instructions written
in the ‘3.2.Positioning And Connections’ and
‘4.Operation’ sections.
3.2.Positioning and Connections
3.2.1.Dimensions
Figure 2. Pump Dimensions
3.2.2.Connection and Assembly
Figure 3. Top View of Pump
The connection of pump to base is done from the
bottom of the pump with 4 x M10 screws.
A permanent installation will not only reduce the
noise and vibration but also increase the
performance of the pump. In permanent
installations it is advised that the base chassis
installed to the ground by a anchor bolt and then
the pump screwed to this chassis.
Figure 4. Anchor Bolt Box
3.2.3.Base Plate
The base plate must be earthed whatever the
type it is.
A. In permanent installations, the base plate
anchored to the prepared concrete platform. The
platform must be in balance before the
anchoring.

6
Figure 5a. Permanent Installation
B. In flexible installation, the base plate stands on
the vibration chocks. Thereby the system can not
be effected by the other vibration sources in
around.
Figure 5b. Flexible Installation
C. The adjustable installation is useful when
there is no balanced concrete platform. The base
plate is consist of adjustible legs under to
balance the base easily.
Figure 5c. Adjustable Installation
D. In a portable stand, the pump and the electric
motor is installed on a moving base plate.
Thereby the system can be easily moved to
desired location in anytime.
Figure 5d. Portable Installation
3.2.4.Flange Couplings
The pump has two access points; inlet and outlet.
The pipe comes from the fuel tank is connected
to the inlet and the pipe goes to desired place of
the fuel or the meter is connected to the outlet of
the pump.
The inlet and outlet of the pump must be chosen
correctly before the installation.
THE FLANGE COUPLINGS
MUST BE DONE BY THE
EXPERT PEOPLE!
Be sure the flanges are parallel before
connecting them. Any deviation in parallelism will
cause of a stres on the pump casing. You can
make the parallelism between the flanges
whether aligning the tube system or putting
shims between the flange and the tube.
Do not exceed the torque values in the flange
couplings. The values in the table are the
maximum. The necessary torque value is related
to leakage, shape, material and the temperature
to the pumping liquid.

BE SURE THE PUMP SHAFT
IS ROTATING EASILY AND
NORMALLY BEFORE
CONNECTING THE PUMP
AND THE MOTOR!
Angular Alignment: The coupling is checked in
four points in all 90º angles. Aim of this checking
is to equalize the distances in every points of the
couplings. The 4 points, 90° distant from each
other, between the couplings, can be set by a
centill, can not be longer than 0.127 mm.

7
Figure 6a. Angular Alignment – Top View
Figure 6b. Angular Alignment – Side View
Parallel Alignment: The pump and the motor
shafts axises (centers) must be checked after the
couplings is secured to have equal distances in 4
points. Check the pump and motor shafts centers
using a straight edge. Put the straight edge on
the couplings in 4 points 90° distant from each
other two or more times. Any alignment problem
shows itself by a line gap between the coupling
and the straight edge. This problem can be
solved by sliding the motor to the right or left, to
put some shims under the motor or take back.
These four distances between the couplings can
not be more than 0.127 mm.
Figure 6c. Parallel Alingment – Top View
Figure 6d. Parallel Alignment – Side View
The wrong alignment between the pump and the
motor causes of faster and excessive outwear in
the couplings and the bushings of the pump and
the motor.
The figures show the right coupling
alignment;
Figure 7a. Right Alignment – Top View
Figure 7b. Right Alignment – Side View
3.2.6.Belt Drives
A belt drive is more tolerant than an in-line drive
because of the rubber belts. To align the pump to
the motor, a straight edge used by leaning to the
pulleys.
Figure 8a. Angular Alignment – Top View
In the upper figure; the pump pulley is completely
adjacent, on the other hand the motor pulley
touches in just one point to the straight edge.
This is the reason of the angular alignment.

8
Figure 8b. Parallel Alignment – Top View
In the upper figure, the motor pulley is parallel to
the straight edge on the other hand but there is a
gap between the staight edge and the pulley.
This problem can be solved by sliding the pump
to forward or backward.
Both the angular and the parallel misalignment
have the negative effect on the belts. Not also
the belts outwear faster but also the electricity
consumption increases because of the excessive
friction.
The figure shows the right pulley-belt
alignment;
Figure 9. Right Alignment – Top View
Belt tension control
The stretch portion of the belts are calculated as
1.5 mm for 100 mm axis distance (the axises of
the shafts of pump and motor) and have to
controlled at the middle of the axis. The
extension of new belts after 15 hours of operation
are about %80 of whole extension. If the belts
have to be stretched, with the parts on the motor
plate, the tension is to be adjusted.
The instructions have to be obeyed while
operating with belts:
Before the operation, the belts are streched as
told upwards.
•Be sure that the pulleys are in the same
direction and the shafts are parallel to each
other.
•Use appropriate belt control device for the
tension of the belt.
•If there is no controlling device, use your
thumb for the control.

3.2.7.By-Pass Valve
The pump is under high pressure when it is
operating. At the moments when the liquid
transfer is stopped, this pressure forces the
pump casing, idler and rotor and causes of
outwears and break downs. The designed by-
pass valve system coupled to the pump casing is
sufficient if the pump operates under technical
specification limits and no need to add a safety
valve on the piping.
If a safety valve need to be installed on the
piping, it must be set between the pump outlet
and inlet. Thereby if there isn’t any liquid transfer,
the pressure under the pump parts will be
minimized.
Figure 10. By-pass Valve

9
3.2.8.Piping Configuration
The pump and the piping shall designed to
prevent the flow of the liquid from the pump
when the system is closed. One way to do this
is to hold the inlet and outlet below the
connected piping system (drainage position). At
the same time it is prevented that the pipe
system must not force the pump casing
excessively. The pipes and the liquid passing
through inside it causes of stress on the
connections. For this purpose the pipes should
be supported by the hangers and carriers. Avoid
using 90° joints as much as possible.
Figure 11a. Piping - Supports
Flexible connections could be used in the piping
system. By this way it is prevented that the
possible vibration on the piping system damages
the pump. Vibration causes of leakages from the
flange couplings in time.
Figure 11b. Piping – Flexible Connection
One of the important subject when piping is the
pitch angle of the pipes. The air particles in the
liquid could make up air pockets in the piping
system. This situation effects the pump
performance, causes of decrease in flow, on the
contrary causes of increase in the speed of the
pump and the electricity cost.
Figure 11c. Piping – Air Pocket
It is satisfied that the liquid stays in the pump by
setting a check valve in front of the inlet of the
pump. Thereby the time of the dry running at the
beginning of the operation while waiting for the
pipes to be filled is minimized.
Figure 11d. Piping – Inlet Check Valve
The movement of the liquid backwards could be
prevented by setting a check valve after the
outlet. The check valve has an assisting effect to
the beginning start-up by reducing the difference
pressure in the inlet and outlet.
Figure 11e. Piping – Outlet Check Valve
The pump dispatches with the gaskets uncut in
the inlet and outlet. The aim of this is to prevent
accessing unknown particles in front of the pump
while shipping or piping work. When the piping
work finishes, the gaskets will be used after
cutting in the dimension of the flange. Before the
piping work, there are labels on the gaskets show
the inlet and outlet.
The pump should be mounted to a cabinet or
somewhere else where it could be protected from
the outer effects. The connection points must be
tight. The untight connections may expose the
pump to vibration. Also the liquid can leak from
these points and can effect the measuring
accuracy.

10
WHEN DOING INLET AND
OUTLET CONNECTIONS, BE
SURE THAT THE WELDING
SLAGS / METAL FILLINGS DO
NOT ACCESS IN FRONT OF
THE PUMP!
The screws and nuts tightness must be done
according to the following table. The excessive
torque may cause of stripping of the screw or the
inadequate torque may cause of leaking from the
gaskets.

3.2.9.Direction of Rotation
The direction of rotation of ER 1134Y pump is
shown on the label stitched on the casing. But in
necessary conditions the direction can be
changed.
DO THE DIRECTION OF
ROTATION TEST ONLY WHEN
THE PUMP IS FULL WITH THE
LIQUID. DO NOT RUN THE
PUMP DRY!
It isn’t necessary to disassembly the casing to
change the direction of rotation, changing the by-
pass unit’s place is enough. The pump will have
the same flow rate and pressure for the opposite
direction. The matter here is to change the
direction of rotation means to change the inlet
and outlet of the pump. The inlet of the pump is
going to be the outlet and the outlet of the pump
is going to be the inlet hereafter.
Figure 12. Direction of Rotation
The direction of rotation for the ER 1134Y pump
when looking from the coupling side is; counter-
clockwise if the by-pass valve is set to the left,
clockwise if the by-pass valve is set to the right.
3.3.Earthing
Earth the pump as shown below. Use copper
wire having at least 1,5 mm² section. Fix the wire
to the pump base using base screw. Insert the
other end of the wire to the ground no less than 5
cm.

3.4.Electric Coupling
THE ELECTRIC COUPLINGS
ARE ALWAYS DONE BY
AUTHORIZED PEOPLE
ACCORDING TO THE
STANDARDS AND
REGULATIONS!

11
The electric couplings must be done according to
the instructions and related regulations by a
qualified electrician. Not to obey this instructions
may cause of serious traumas, deaths or
physical damage.
Use a motor switch appropriate to the motor’s
nominal current.
Control the local electric voltage is the same as
the motor voltage written in the label, and the
direction of rotation of the motor is the same as
the pump.
A THERMIC APPROPRIATE TO
MOTOR POWER MUST BE SET
BEFORE THE ELECTRIC
SYSTEM OF THE MOTOR IN
ORDER TO PREVENT DAMAGE
IN CASE OF ANY BREAK
DOWNS OR FORCING!
3.5.Paint
The paint used for the pumps is the Styrene alkid
solvent based primer paint. The high water
resistanant paint protects the pump from
corrosion.
THE PAINT USED CAN BE
RESOLVED IN THE
PETROLEUM PRODUCTS. DO
NOT EXPOSE THE PUMP’S
EXTERIOR SURFACE TO THIS
KIND OF SUBSTANCES!
4.OPERATION
When working with
hazardous liquids or
maintaning the pump, wear
protective clothes, use
protective glasses or face
mask.
To get in touch with
hazardous liquids, to
swallow, splashing to eyes,
to smudge of the body or
breathing the vapours of
them without taking
appropriate precautions may
cause of serious traumas or
even death. Take the
necessary safety
precautions while working
with the hazardous liquids.
To change the parts or
accessories of the pump, to
use outwear or damaged
parts, to use liquids or
chemical substances
inappropriate to inner
mechanism of the pump can
damage the pump parts. In
such a case the subjected
liquid may pour, smudge to
the body or splash to the
eyes. According to the type
of the liquid, this situation
may cause of fire, explosion,
thereby to loss of human life
and property.
The pump consists of
rotating parts. To insert an
organ like finger to these
parts without taking safety
precautions may cause of
woundings or rupturing an
organ.
4.1.Control List
The following clauses must be controlled before
operating of the pump;
1. That the pump should be earthed.
2. That the pump shaft can be turned
around freely.
3. That the pump is connected to an
explosion-proof motor, if the pump is set
up in a potentially explosive atmosphere.
4. That the pump and motor are aligned
precisely.
5. That the thread of the temperature sensor
has not broken off during transportation,

12
handling or installation, if the pump is
fitted with temperature sensor
6. That all isolating valves in the inlet and
outlet pipe are fully open, to avoid the
pressure being too high and the pump
running dry.
7. That any by-pass valve is fitted correctly.
8. That there is no coagulated liquid in the
pump or the pipe system after the last
operation that may cause blockage or
breakdown.
Controlling after a long storage time
If the pump has been in storage for a long period
of time, the followings are to be checked;
1. That the pump is not corroded or dried
out,
2. That the pump shaft can be turned
around freely,
3. That any preservative or anti-frost liquid is
cleaned off before starting the pump if
these are not compatible with the pump
liquid,
4. That elastomers are replaced if they have
been damaged by the anti-frost liquid
used,
5. That gasket and seal maintain their
elasticity. If the pump has been in storage
for more than 6 years, it is recommended
that these parts are changed.
After controlling all these clauses, the pump is
ready for the operating. While the operating, the
gun, valve etc. equipments after the pump must
not be kept close long durations, so the pump
must not be exposed to high pressures.
After the pumping operation, the gun, valve etc.
equipment must be closed and the pump must be
shut down immediately.
4.2.Dry Run
The pump should be protected against dry
running. Otherwise it will expose to unnecessary
abbrasion and breaks down. Dry running causes
heat to develop and the possible creation of
sparks by the pump casing and iner mechanism.
The pumps produced for the potentially explosive
atmospheres must be protected against dry
running.
NEVER DRY RUN A PUMP
BECAUSE OF POSSIBLE
CREATION OF SPARKS
AND MAY CAUSE OF
EXPLOSION!
4.3.Operation Principle
In the following figures, a section of a ER 1134
pump viewed from the front.
The rotor, fixed to the
main shaft, starts
rotating with the drive
and forces the idler
to rotate which is
placed in the rotor
but has a different
axis. Thereby the
flow starts from the
inlet.
The rotor placed
outer is a slower
peripheral speed
than the idler. (The
signs on the rotating
parts give clue about
the rotate operation.)
The liquid fills all the
spaces in the
casing. Rotating
parts force the liquid
to flow in the
direction of rotation.
Figure 14. Operation Principle

13
4.4.Initial Start-Up
In a new and dry system, when the vanes open,
there may be a high pressure in the piping
system and this pressure pass through the
pump by force. The high pressure and the air
volume makes the pump operating faster.
The suggested start-up procedure for any
system is overflowing the piping system
gradually. This enables the pump to discard the
air slowly from the piping.
Protecting Unknown Particles
In new piping systems, attention must be paid to
protect the pump in start-up. Welding slacks,
corrosion, sludges may cause of damage in the
pump. To protect the pump against these kind of
damages, control the filters set up before the
inlet of the pump.
5.TRANSPORTATION-STORING
5.1.Transportation
Figure 14. Packaging
While transporting and carrying, pay attention for
the safety of the pump. The transportation must
be done with the pump’s package.
•Use double layered corrugated card
board.
•The product is folded with the balloon
nylon to protect against dust, moist and
impacts, surrounded by the adhesive
band.
•The folded product put to a box.
•The banded box is reinforced by a plastic
strap.
•The strapped product is ready for the
transportation.
•That put in the car with care not to fall
over or not any materials to fall off above
it.
Use the figure below to carry the pump after
putting out of the box.
Always carry the pump lifting it under the casing.
Never try to lift holding it from the coupling or the
by-pass unit.
Use a nylon rope at least 30 kg tensile force.
Figure 15. Lifting of Pump
5.2.Storing
If the pump is stored for a period of time, the
storeroom must be o dry, clean and free of moist.
Do not detach the gaskets from the inlet/outlet or
cut the closed gaskets until the time of
installation. Clean the pump prior to assembly.

14
1. To store the pump left in the system,
flow about 150 liters of clean water
through the pump.
2.
After that, pump %70 antifreeze and
%30 water mixture to all the system
(instead of the mixture, %100 RV
antifreeze can be used). While the
pump is operating, close one of a
valve after the pump to guarantee
the antifreeze solution will be kept in
this zone. After that close one of a
valve before the inlet of the pump,
thereby you will be sure the pump is
full of antifreeze solution.
3. Before starting the system after storing,
do not forget to apply the clauses
written in the title of “4.1. Control List” .
6.MAINTENANCE
The pumping liquid is
hazardous for the skin. Use
full face mask (if not use
glasses) and wear your
plastic gloves. To protect
your skin against smudging
the liquid.
The pumping liquid is
hazardous for breathing. In
case of breathing, head
ache, vertigo or more
serious health problems
may occur. Stop your work
and go out for a fresh air
immediately!
The possibility of a spark
result to rubbing of two
metals, assembling or
disassembling is very
dangereous when there is
liquid in the pump. A fire or
an explosion danger exists
according to the
specification of the liquid.
The pump consists of
rotating parts. To insert an
organ like finger to these
parts without taking safety
precautions may cause of
woundings or rupturing an
organ.
We recommend you to keep records of the
periodic or other controls and maintenances. To
apply this kind of maintenance procedure will
make your pump work in good condition and
prevent from the high cost malfunctions.
6.1.Filter
The filter should be controlled periodically and
make sure of its cleanliness. That the filter is the
most important equipment in effective working of
the pump has never been forgotten.
FILTER IS AN OPTIONAL
EQUIPMENT. TO USE OF IT IN
FRONT OF AN INLET OF THE
PUMP WILL MAKE THE PUMPS
PHYSICAL LIFE LONGER!
Figure 16. Disassembly of the Filter
A disassembly of an IPT marked filter shown in
figure. After untighten 6 pieces of M10 screws,
the cover is detached. Now it is possible to reach
the filter. The filter keeps the possible unknown
particles in the liquid flowing to the pump, that
means the inside of the filter will be dirty and the
outside of its will be clean. After detaching the
filter, clean it by exposing the outside of it to the
pressurized air.
BECAUSE OF NOT
PROTECTED AGAINST
UNKNOWN SUBSTANCES,
PUMP USING WITHOUT
FILTER IS OUT OF
GUARANTEE!

6.3.Junk Pump
Take the cautions to prevent the environment from the risks of the pump can damage.
• Empty the pump completely.
• The pump is made of recyclable materials as iron, steel etc. Make effort for the recycling.

6.4.Periodic Maintenance
MOUNTLY
Measure the temperature of the bushings by a thermometer not by your hand. The
working of the bushings in high temperature (over 60°
C) may be the result of
outwearing of the teflon. Dismantle and change the bushings.
The impermeab
ility materials as elastromers (seals) may cause of the high
temperature. To correct the situation, oil the impermeability materials.
3 MONTHS
TIME
Control the bushings against outwear. If there has not been unknown particles or has’nt
been accessing any dust from seal, there won’t be a problem. If there is a problem as
being outwear or damage, changing will be a good solution. Also the bushings are
changed for the beter performance.
6 MONTHS
TIME
Control the gasket or the seal and change if necessary. Use the suggested class. Be
sure the gasket/seal is in the proper place.
Take the records of the vibration values in the casing. Compare the values (previous
and actual) due to a possible malfunction pump part.
Control the shaft due to the scratcs. The scratcs speed up the abbrasion of the gasket.
Check the alignment of the pump and the motor. Calibrate the system if necessary. If
the alignment problem
repeats time and time again, control the whole piping system.
Control whether there is a flexion in the pipes after untighten the bolts on the inlet and
outlet flanges. By this way, determine the stress on the pump casing. Check all the
pipes whether they are supporting effective weight support. Fix properly if necessary.
ANNUALLY
Detach the back cover. Check the pump well against abrasion and order new spare
part if necessary. Control the idler and the rotor gaps. When the gaps become as three
times more than the original or a noticeable pressure loss for the same motor speed,
change the idler and the rotor.
Clean the sludges. Measure the total dynamic pressure and flow rate. Record the
numbers and compare them with the accurate ones. This is important when the liquid
makes sludges up in the casing.
Check the by-pass unit coupled to the casing. Check the by-
pass vane to set for
assisting the by-pass unit especially with the stopping of the flow when the pump is still
operating.
NOTE: The schedule upwards was prepared in the assumption of the pump has been checked regularly
and it was noticed that this kind of a schedule is appropriate to the operating. When determining the
maintenance periods, excessive or off-beat procedures or conditions must be considered.

The Possible Solutions
Cause
Solution
01
Control the fuel tank. Be sure the piping system is under the liquid level.
02
The motor may be too powerful for the pump, the appropriate one must be chosen.
The inlet piping may be smaller than the necessary, consult to IPT.
03
Find the source of leakage and prevent all the leakages. The pump can not maintain its duty
because of air suction. This can be tested by closing the beginning of the inlet piping or sending
pressured air in the piping system. The gauge shows the leakage as decrease in the pressure.
04
Control the voltage of the motor. Check the rpm value in the marking of the pump versus motor
rpm.
05
Check the rotor, idler, bushings and the shaft. Change the parts which were worn, or damaged.
06
The liquid may dilated due to temperature and the liquid may become thinner. The fuel tank and
the piping should be get colder.
07
Be sure there isn’t any closed valves to prevent the incoming or outgoing of the liquid to the
pump. There may not be any liquid in the inlet side.
08
The electric voltage or frequency may be lower than the determined or there may be a fault in the
motor. The motor is not ventilated because of wrong placing.
09
You can adjust the pressure partially by opening or closing the by-pass vane grade by grade. Be
sure the inlet side piping has the sufficient width.
10
Be sure the by-pass unit coupled to the pump casing is working properly.
11
The pump had to carry the piping system weight. Immediately support the piping system with the
hangers or carriers. Do not let the pump carry the piping system’s weight.
12
Check the alignment. Check the pump for the abrasion between rotor, idler and casing. Change
