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
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 :

against casual engagement. Some pumps 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.
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 .
Before starting any installation action the
current must be cut off. It must be secured
