UWAGA The pumps and hydrophores have a maximum suction capacity of 8m water
column. However, it should be remembered that the section called the water column consists
of the distance from the water level to the pump, both vertical and horizontal. In addition, the
diameter of the pipe is also important.
- Every 1 meter vertically is counted as 1m water column.
- Every 1 meter horizontally at the pipe with a diameter of 1 "should be counted as 0,15m
water column (It should be remembered that in periods when rain falls rarely and also
during summer periods, water mirrors tend to fall).
Example:
The booster set is set at the distance of 10 m from the well where the depth to the water level
is 5 m. A suction pipe with 1" diameter was used in assembly. The negative pressure
connected with the depth is 5 m. The negative pressure connected with the length and
diameter of the suction pipe is (5vertical section+10horizontal section) x 0.15for diameter 1"
= 2.25 m In total, the negative pressure is 5_2.25 = 7.25 m. In this example the negative
pressure of 8 m is not exceeded and the booster pump should operate without problems. If the
negative pressure of 8 m is exceeded during operation (e.g. when the water level decreases
during pumping), the booster pump can be damaged due to operation without water flow. This
type of failure is not subject to warranty repair. Bearing the aforementioned in mind, if it is
possible that the water level will decrease, e.g. during droughts or intensive plant watering,
the booster set must be installed in such a manner that a possibly high negative pressure
reserve is preserved. For this purpose, it is preferable to install the booster set or pump at a
short distance from the well and the recommended cross-section of the water pipe to use is
1

CAUTION Using suction pipes with diameter lower than 1" is prohibited. In such a case, the
booste pump will not start pumping water, and if it starts - it may be damaged due to lack of
water flow. This type of failure is not subject to warranty repair.
CAUTION Any leakage in the suction system will cause the pump's ability to suck in water,
which can lead to "dry running" and destruction of the pump.
CAUTION You
- The higher the efficiency of the pump, the greater the losses.
- All valves, elbows, reductions, flow meters, tees, nipples increase losses on both suction and
discharge.
CAUTION The pump and pressure booster system should be selected so that the number of
on / off cycles does not exceed 16 times per hour.
CAUTION The pump is dedicated to pumping clean water with a maximum temperature
of 35 ° C.
CAUTION The pump is not suitable for pumping substances such as: acids, solvents,
alkalis, oils, petrol, petroleum and other explosive substances and caustic solutions that may
damage the device. Damage resulting from pumping of the above-mentioned substances will
void the warranty.
CAUTION The pump is not suitable for pumping water with an excessive amount of
minerals that can cause scale buildup on the pump's hydraulic components. Pumping water or
should additionally keep in mind:
