Intended use:
GARDENA Electronic Pressure Pumps have been
designed for private use around the house and
garden. Electronic Pressure Pumps are predomi-
nantly used for operating watering systems and
systems in private gardens.
When using the pump for pressure intensifi-
cation, the maximum permissible internal
pressure of 6 bar (on the delivery side) must
not be exceeded. The delivery pressure to be
increased and the pump pressure have to
be added together.
• Example: pressure at the tap = 2.0 bar,
maximum pressure of the Electronic Pressure
Pump 3500/4E = 3.5 bar, total pressure
= 5.5 bar.
Liquids pumped:
The GARDENA Electronic Pressure Pump can
be used for pumping rainwater, tap water and
chlorinated water.
IMPORTANT! The GARDENA Electronic
Pressure Pump is not suitable for continuous
operation (e. g. industrial applications, con-
tinuous circulating operation). Corrosive,
easily combustible, aggressive or explosive
liquids (such as gasoline, petroleum or
nitrothinner), saltwater and food intended
for consumption must not be pumped.
The temperature of the liquid must not
exceed 35 °C. Before the beginning of the
frost period, the Electronic Pressure Pump
must be drained and placed in frost-proof
storage (see 5. Storage).
