GENERAL FEATURES
The main purpose of a water booster is to keep the pressurized water in the
installation ready for use at any time.
There are three main parts in a water booster.
- Motor and Pump (Motopump)
- Automatic Control Equipment:
- Pressure Compensating Tank (must be purchased separately)
Motopump: It pressurizes water. ALD water booster motors are three-
phase and vertical.
Automatic Control Equipment: It is the equipment that provides the automatic
operation of the water booster according to the pressure changes in the installation
and whether the feed water is available.
Pressure Compensating Tank: Its main purpose is to compensate pressure changes
in the installation and to keep the number of commissioning and decommissioning of
the pump (number of switches) in the most appropriate number.
Figure 1: Water Booster with Triple Pump Diagram
Note
Ball valve is not supplied with the water boosters with single pump.
Tank and flexible hose should be ordered separately in all water boosters. Standard
delivery does not include tanks and flexible hoses.

INSTALLATION RULES
Location Selection:
The place where the water booster will work should be closed in such a way that
it is protected from external factors such as rain and frost. It should be placed in
such a way that it is not affected by heat sources such as burners and boilers that
may be present in the vicinity. Gaps should be left around the water booster for
maintenance and repair purposes.
If the water booster is to be fed from the tank, the distance (horizontal) between the
tank and the water booster should be at most 10 meters.
Water Suction Installation:
The water booster should be fed from the water tank. Do not connect directly to
the municipal water system.
The bottom of the tank should be in the same plane as the water booster. This
ensures that there is always water in the water booster suction inlet and prevents the
pump from producing air.
Suction from the tank at the lower level should never be done. Damage that may
occur on the water booster as a result of such applications is not covered by the
warranty.
All connections in the suction line must be sealed and air must not enter the
suction pipe.
Pumps should not be forced during water suction. For water boosters with single
pump, the diameter of pump suction pipe should be one size larger than the water
inlet diameter, and for water boosters with twin and triple pump, the diameter of pump
suction pipe should be the same with the suction collector diameter. Inner diameters
of plastic pipes are narrow compared to galvanized ones. If a plastic pipe is to be
used, the dimension providing the inside diameter of the galvanized pipe should be
used.
Other Installation Conditions:
The water booster inlet must be fitted with a gate valve, and its outlet must be
fitted with a gate valve and a check valve. Thus, it will be possible to remove the
water booster from the installation for maintenance and repair.
It is preferable to connect the water booster to the installation with flexible hoses.
Thus, the loads in the installation will not be reflected to the water booster and
the vibration and sound of the water booster will not pass to the installation.
The water booster must be fixed to the floor with bolts. In this way, the sound from
vibration will be prevented to a great extent.
Water Properties:
The water to be used in the water booster should be clean, free of solid particles and
temperature between 0-35 ºC. Ambient temperature should be maximum 40 ºC. The
water in the water booster should not be allowed to freeze.

10
The recommended assembly patterns are shown in the diagrams attached to this
manual.
Precautions to Extend the Service Life of Mechanical Seal:
The mechanical seal is one of the most sensitive parts in the water booster.
Inaccuracies or inadequacies in the installation and operating conditions cause the
shaft seal to break down rapidly. The normal life of the mechanical seal is 8,000 hours
under clean, cold (20°C), solid particle-free (without sodium carbonate, calcium
carbonate) water conditions. Mechanical seal works according to the principle of
forming a water film layer between carbon and ceramic or stainless surface. This
water film layer formed during operation allows the surfaces to slide on each other
without friction. Water also serves as cooling. Lack of water film layer and the dry
running of the seal surfaces by rubbing against each other without a water layer
between them causes burns and deteriorates them within 3-5 minutes.
The mechanical seal is at great risk in the following incorrect or inadequate operating
conditions;
• If the motopump is sucking from the tank at the low level; This type of installation
should not be done. There is a possibility of leakage of the valve at the suction end. In
this case, the water in the suction pipe drains into the tank, no water remains in the
pipe, the pump runs without water.
• If there is a strainer, check valve etc. between the motor pump and the tank: If the
bottom of the tank is at the same level as the water booster base or the tank is higher
than the water booster, a check valve is not required in the suction line. The check
valve makes the water flow difficult. This is also a potential congestion point. The
strainer should be checked and cleaned frequently. Otherwise, the water flow will be
blocked and the pump will run without water or with insufficient water.
• If there is sand in the water: Sandy water will also penetrate into the film layer and
corrode the surfaces, causing the seal to deteriorate.

WATER BOOSTER OPERATION
1- Check the compatibility of the water and electrical installation.
2- Check that there is sufficient water in the water tank.
3- Check that the waterless running protection (if any) is properly installed.
(See page 21 for details)
4- Check that the membrane tank has been installed correctly and that the pre-gas
pressure is appropriate. (See page 13 for details)
5- Fully open the water inlet valve to the water booster pump.
6- Slightly loosen the bleeder plug of the water booster pump (if equipped). If the
water level in the tank is higher than this point, water will leak from this plug after a
while. If the water booster is to work by suction, fill water from this part. Then close
the plug firmly.
7- Run the pump(s) briefly in a controlled manner. Check that the pump shafts
rotate in the correct direction. If their direction of rotation is reversed, the terminals
in the electrical connection must be repositioned.
8- Check that the pump(s) are running within the required pressure ranges. (See
Table 15 for setting the operating pressure range of the pump)
9- For multi-pump water boosters, check that the pumps rotate each time they run.
If the same pump always runs, there is a fault in the pressure switch connections.
Check it from the diagram.
10- The commissioning of the water booster is complete.

MEMBRANE TANK (Pressure Compensating Tank)
There are different applications for membrane tanks in water boosters;
ALD and ALDF Water Booster:
The user must use a membrane tank with the motopump assembly. The
selection, installation and pressurization of this tank are described below.
Note: These calculations are for finding the minimum value of the tank volume. There
is no inconvenience in using tanks larger than the value obtained from the
calculation. As the tank volume increases;
- Pressure fluctuations in water reduce.
- The commissioning and decommissioning sounds of the motopump reduce.
- The service life of the motor extends.
- Energy expenditure reduces.
In industrial applications where the water consumption rate is more standard
than for social use, a smaller tank can be selected.
0,33*Qmax*(Pmax+10)
Vtank =--------------------------------------------------
△P*a
Vtank : Volume of tank to be used (liters)
Qmax : Total flow rate of the pumps at operating pressure (liters/hour)
Pmin : Starting pressure of pumps (mSS)
Pmax : Stop pressure of pumps (mSS)
△P : Pmax-Pmin
a : Number of switches to be considered for motor (number/hour)
Note: In the “1999 Unit Price and Tariff Book”, the Ministry of Public Works indicated that
the number of switches should be maximum 180 times/hour for engines up
to 1.1 kW
and maximum 40 times/hour for engines above 1.1 kW.
The volume of the membrane tank to be selected for ALDF must be at
least 10% of the membrane tank volume calculated for ALD.
Caution: The maximum operating pressure of the membrane tank must be
higher than the maximum operating pressure of the pump.

13
CONNECTION OF MEMBRANE TANK
The duty of the membrane tank is to reduce the number of switches (the number of starts
and stops of the motor within 1 hour). Thus, the motopump does not need to be
commissioned for small-scale uses. Therefore, the larger the tank, the lesser the number of
switches.
Membrane tanks can be connected to the motopump assembly in two ways.
1- Connection to Collector:
There is a membrane tank connection outlet on the water booster pressure collector. The
tank can be connected with a flexible steel braided hose, galvanized pipe or plastic pipe. In
this connection, a piping at least at the membrane tank outlet diameter in the water booster
pressure collector should be used. If the installation has a small diameter, the water transfer
rate between the tank and the installation decreases. The required efficiency cannot be
obtained from the tank. There may be disruptions in the operation of the water booster.
2- Connection to Installation:
It is possible to connect the tank directly to the installation. In this case, the membrane tank
connection end in the collector should be closed and the total distance of the tank to the
motopump assembly should not exceed 5 meters. Otherwise, the pressure switch will be
delayed to detect pressure changes and irregular operation may occur.
PRE-GAS PRESSURE SETTING OF MEMBRANE TANK
Motopump assembly can not be used without tank. An active tank must be used. Konforal
membrane tanks can be used for this purpose provided that the operating pressure values
are appropriate. When the membrane tanks are shipped, very little amount of gas is
pumped into them. The air pressure of the membrane tank should be adjusted according to
the conditions of use.
Tank Pressure = Water Booster Operating Pressure - 0.5 (bar)
Tank pressure for ALDF = Water booster set pressure x 0,7
Example 1:
If the booster is operated between 5-7 bar, the air pressure of the tank should be 4.5 bar.
Example 2:
The pressure of the tank of a water booster with triple pump with pressure switch
adjustments of 5-7, 4.5-6.5 and 4-6 bar should be 3.5 bar.
The table below has been prepared to assist the users for operating the ALD water boosters
with the assumption that the water booster will operate at the pressure values on page 16.

While the air is being pumped, the water booster must be disconnected from the water
in the installation and any water remained in the water booster must be drained.
Otherwise, the static water pressure of the building will cause additional pressure in
the tank and the correct adjustment will not be made. A compressor or pedal air pump
can be used to pump air.
Caution:
It is inconvenient to use tanks (galvanized tanks) where air and water are in direct
contact as water booster tanks. Because in such tanks, the air in the tank dissolves in
the water and continuously leaks from the tank with the water. In the motopump
assembly, there is no air suction device to reinforce this decreasing air. Therefore, the
motor-pump does not reinforce the decreasing air in the tank. The air ends after a
while. The tank is completely filled with water and becomes unable to function. The
number of switch of the motors increases excessively.
Caution:
The pressure of the air in the membrane tank should be checked periodically (every
month, etc.). The air reduces by diffusion through the rubber membrane inside the MT
into continuous water or by leaking in the flange and valve connections. If the air
pressure drops in the tank, the number of switches of the water booster increases.
Therefore, fluctuation in sound and water increases.

PRESSURE SWITCH ADJUSTMENT BY DEVICE TYPE ON ALD WATER
BOOSTERS
The pressure switch adjustment for water booster with single pump should be
made by the service at the place of use according to the table on the back page.
The pressure switches of the water boosters with twin and triple pump are adjusted
at the factory and shipped according to Table 3.
Water Booster with Single Pump:
The "Pressure Switch Setting" procedure on page 15 is applied.
Water Booster with Twin or Triple Pump:
Note: In the water boosters with twin and triple pump, there is a delay of about 3
seconds for the motopump to detect the signal to prevent the pressure switch from
being affected by the water hammer pulse. This delay should be considered as
standard deviation during adjustment.
The water booster must be operated in manual mode for adjustment.
CAUTION: In manual mode, the pressure switch is activated and stops and start
the motopump according to its output.

16
The pressure switch adjustment should be made as follows.
1.Determine which pressure switches should be set to which values according to
the table below.
2.Set the water booster to manual mode. For this purpose, press button 2 shown
on page 20 for 10 seconds.
3. It is enough to use only one motopump when adjusting the pressure switch. The
pressure in the installation will be increased by running the motopump, the pressure
will be reduced by draining the water from the drain valve (or waiting for the water to
be used in the installation). Pressure switches should be adjusted during these
pressure changes.
4. Run the motopump. The key 6 is used for this purpose. Once the key is pressed,
the motopump starts. If it is pressed again, the motopump stops.
5. Firstly set the low pressure switch. Use the short and long bolts specified above
for this purpose.
6. If the water booster has two pumps, the operation is ended by adjusting the high
pressure switch. If it has three pumps, after the low pressure switch, the medium
pressure switch should be set and then the high pressure switch should be set as
well.
7. After the pressure switch adjustment is complete, press key 3 shown on page 20
to set the water booster to automatic mode.
8. In automatic mode, check that the water booster operates at the desired pressure
values and that the motors are switched on and off in sequence.
