APPLICATION:
Pumps referred to in these instructions are designed to pump clean water from the
drilled deep-water intakes or to increase pressure in water supply systems when the
unit is built-up in an air-tight coat.
Pumps can be used in a household (for water supply), at farms (for irrigation), in
heat pumping systems, for water supply for industrial systems.
The pumped water must not contain mechanical impurities.
The pump is designed to pump water without solid or grinding parts.
Pumping water which contains sand leads to rapid wear and in consequence to
damage. In such case the repair may be performed only against payment.
The foregoing does not refer to pumps 4SD nor 4SDM with increased resistance to
sand. For these pumps the permitted content of sand in water may not exceed 5%.
Please remember that lifecycle of the pump with increased resistance to sand will be
much shorter if the pump pumps water contaminated with sand. Wear of the
elements pumping with sand is not covered by the warranty. It is an operational
wear.
The pump is not fit for pumping corrosive, flammable, degrading or
explosive substance (e.g. gasoline, nitro solvents, petroleum etc.), food
stuffs, salt water. Damage caused by pumping these types of liquids in not
covered by the warranty.
Permitted temperature of the pumped water is 35
o
C.
The pump is not fit to pump water containing excessive quantity of
mineral components causing scale deposits on pumping elements. Using
the pump under such conditions leads to premature use of the operating elements. In
this case the repair may be performed only against payment.
The pump must not pump water containing oils or petroleum-derivatives.
The pump’s operation in such water damages rubber elements e.g. cable and
seals and in consequence leads to unsealed of the motor and damage. In this case the
repair may be performed only against payment.
INSTALLATION OF THE PUMP:
Before starting any installation action the feed
current must be cut off. It must be secured against
casual engagement.
Pumps 4SD, 4SDM, 90QJD, 3ti due to their size may be supplied in two parts. One is
the hydraulic part of the pump, the other one is the electric motor.
Before assembling the two parts into one unit undo the screws mounting the cable
protective strip. Then undo the screws mounting the filter screen and remove it.
Undo and remove the assembly nuts and pads from the motor.

3
After the motor has been positioned vertically put the hydraulic part on it so that the
motor shaft ended with multispline is placed in the pump clutch. In case of problems
with composition during the placement, turn the motor shaft in order to adjust the
multispline to the motor clutch.
When the hydraulic part is properly placed on the motor, it should be fully based on
the upper bearing casing of the motor. Having prepared the unit in this manner, you
can start the assembly using nuts and pads.
The nuts must be tightened in a "criss-cross” pattern. The minimal moment for
tightening the nuts is 18 Nm.
Inaccurate tightening of the nuts may cause their release during operation
and „sinking” of the motor in the borehole.
After the hydraulic part has been mounted on the motor and the feed cable has been
placed on the pump, put and tighten the filter screen and then the cable protective
strip.
Lowering the pump in the borehole with a protective strip may
damage the cable insulation. This may damage the pump or cause
electric shock to the operator.
Since the motor needs cooling during operation, the diameter of the
borehole where the pump is working may not be greater than the value
given below in the table of diameters. The values are given in mm. These diameters
depend on the working capacity of a given pump and dimension of pump.

Using the pump in a well of a diameter greater than the
one given in the table might overheat and damage the
motor. If the diameter of the well where the pump is to be
working is greater than the diameter given in the table, the pump
must be installed in a special coat which enforces proper cooling.
The concept of the coat has been shown in the figure.

4
The pump must be installed above the filter of the well. The minimal
distance between the upper edge of the last part of the filter and the lower
edge of the motor may not be less than 30 cm.
The pump may not dry run, without water. Dry run damages the
equipment. In this case the repair may be performed only against payment.
To prevent potential dry run the pump must be installed at such depth so that the
lowest dynamic level of the water (water level established during continuous
pumping at free outflow) is at least 2 m above the liquid feed port of the pump.
If the efficiency of the well prevents such assembly (the well is not as efficient as the
pump) then choose an option from the following:
- install smaller pump
- install a valve for constant reduction of the flow on the delivery pipeline,
- install a safety device against dry run to control the level of water table and in
case of dry run to cut off the power supply to the unit.
When lowering the pump into the well make sure that the feed
cable of the pump is in at least 2m mounted to the delivery pipe with
plastic bands. At a great depth where the pump is installed the cable which is not
mounted to the delivery pipe may break reason high weight of cable.
I It is recommended to lift the pump additionally at a steel line so that in
case of self-rewinding of the delivery pipeline the unit does not sink in
the well.
Right over the pump install a non-return valve to protect the equipment
against the impact of the returning water. The non-return valve installed on
the pump is an auxiliary valve, it may not be treated as the main valve.
The pump’s motor is filled with an environment-friendly oil. In case of a
motor breakdown the oil might be released to the well.
Before lowering the pump into a new well, the user should make sure
whether the drilling company which executed the well has cleaned it by
pumping the water out. When executing the well the water inside the protective
pipe and inside the filter is contaminated with sludge and sand.
Pumping the water containing sand reduces significantly the lifecycle of deep-well
pumps.
When setting the pressure switch and choosing the capacity o
of pressure vessel it is necessary to comply with the rule that
the pump motor may not switch on more often than 30 times
per hour. More frequent switching on might overload and damage the
motor.

ELECTRIC CONNECTION:
The electric network from which the pump is to be supplied should have nominal
values as given in the date plate of the motor.
The pump must be connected to the network with active earthing.
The manufacturer and the warrantor is released from liability for
damages to people or objects resulting from the missing proper earthing.
The electrical network feeding the pump must be fitted with an
installation over-current motor switch securing the motor against
overload. To ensure proper protection of the motor, the switch should be set for the
winding current absorption given on the data plate in Ampere [A].
The pump may work without such switch but in case of damage caused by overload,
the costs of repair be covered by user.
The electric installation feeding the pump should be fitted with a
residual current device (RCD) of nominal operating current of I
n
not grater than 30 mA. The manufacture and the warranter is
released from any liability for damages caused to people or objects resulting to
feeding the pump without proper switch.
Pumps 4SDM, MSC reason short length of cable are
supplied with separate control box equipped with capacitor,
overload protector and switch ON/OFF. Control box must be connect to pump
cable. Method of connections are showed in inside cover of control box. Cable
with electric plug is connected in factory. User must connect only cable from
motor.
Peo
ple and animals must not remain in water where
the pump is running.
In case of damage to insulation of the feed cable it is forbidden to use
the pump. In such situation contact the warranter to replace the cable.
Mechanical damage is not covered by warranty. Using the pump with
damaged insulation of the cable may lead at least to flooding of the motor, in the worst
case to electric shock.
Before starting the pump check the voltage at the cable end. Note
that at farther parts of the cable at its end the supply voltage
decreases. Permitted decrease of voltage for the applied motors is ± 6%.
In order to avoid excessive drop of the voltage select proper cable according to the
motor power, length of the cable. See the table below to choose the right cable:

Non-compliance with the above instructions on selection of cable
reduces the voltage excessively and in consequence overloads and
damage the motor.
The pump is originally fitted with a short section of the cable. Depending on the user’s
needs the cable is extended. Water tight connections of cables must be executed by a
person having proper knowledge and experience. The user should commission the
assembly to a well driller company or can do it in a store he bought the pump.
Non-professional connection and insulation of the cables may cause that the
residual current devices will knock out, the motor will be flooded or the user
maysuffer electricshock.
STORAGE:
Clean pump must be stored in a dry place.
Make sure that the pump is placed on even surface on entire length. The
pump’s support in one or several points may bend the pump and cause
damage.
EQUIPMENT DISPOSAL:
The used product must be disposed as waste exclusively in selective
waste collection organized by the Public Network of Electric and
Electronic Waste Collection Points. The consumer may return the used
equipment to the distributor of electric equipment, at least free of charge and
directly provided that the equipment is of the right type and the same functionality
as the newly purchased one.

POTENTIAL PROBLEMS DURING OPERATION AND SOLUTIONS:
© & ™ All rights reserved by PHU DAMBAT
Symptom
:
Possible cause:
Solution to the problem:
The security device against dry run has
been engaged
Wait until the quantity of water in the well
is sufficient so the pump is switched on
automatically.
The security device against over-current
has been engaged
Wait until the motor cools down and
switch on the pump.
Check the cause of the overload. Remove
the cause.
Make sure the electric plug of the pump is
properly inserted in electric socket.
Check the corks at home and all installation
switches which may cut off the power
supply from the network
The pump is not
running
No power supply
Check if power supply is ensured near your
house – the power company may have cu
t
off power in a larger area.
A break in one wire of the feed cable Check resistance between the cable wires
The pump keeps
switching on and
off
Incorrect voltage or drop during start-up
Check voltage
The filter screen is blocked at suction
Disconnect the pump from electrical supply.
Take the pump out of the well and clean
the filter
Incorrect direction of the motor revolution
(Valid only for 3 phase motor)
Change the two veins of the feed
cable on the feeding strip (only for
three-phase motors)
Too high resistance during the flow
through the delivery pipe (hose).
Check if the permitted lifting height
for this
specific type of pump is not exceeded .
The
lifting height to be generated by the pump
depends on the level difference between
water table in the well the water is pumped
out and the level at which the water is
pumped , the length of the delivery pipe
(hose) and its diameter . If resistance is too
high for this specific type of pump replace
the pump with a different one, of greater
Sand in the pump (dirty water)
Remove sand from the pump. Clean the
well.
Supply voltage is too low Check the supply voltage
The pump is
running but is
not feeding
water or is
feeding too little
water
Too little water in the well
Check the pump’s position. The pump’s
fuel feed port should be at least 2 m from
the lowest dynamic level of water table.
Pressure vessel is too small Replace the vessel with a bigger one
No airbag in the pressure vessel
Check the air pressure in the vessel.
Add if necessary. If the situation repeats
often check if the diaphragm in the vessel
is not broken
The difference between the switching
on and switching off pressure at
pressure switch is too small
Adjust the switch
Frequent switching on
and off the pump
Suspended non-return valve Take the pump out and replace the valve.
