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.
