What liquids are GARDENA pumps suitable for transferring?
Pumps are suitable for pumping mains water, rainwater and pool water containing chlorine. After pumping chlorinated water from a swimming pool, the pump must be flushed with warm (but not hot e.g. not 35˚C or above) fresh water.
Pumps are NOT suitable for salt water, hot water (35˚C or above), flammable materials, gravel, sand or liquid containing food stuffs. Sand and gravel are very hard and can therefore damage the blades of the pump’s impeller. GARDENA pumps are not certified or recommended for use with drinking water.
How long can pumps be operated without pumping water?
This should always be avoided at all costs as there is a risk of overheating and damage. With garden pumps and submersible pumps, the maximum would be 5 minutes, however having the pump on without pumping water should always be avoided.
What is the automatic function on a pump?
The automatic feature on selected pumps starts (cuts in) and stops (cuts out) the pump automatically when water is needed. This is a requirement for domestic water supply. The benefits of this feature are convenience, energy saving and less wear on the pump.
How do I prime a garden pump?
Pumps are primed by adding water to the inlet area (where the filter is located on a automatic home and garden pump).
Why is my pump not pumping water?
The motor hums but there is no water flow through the pump. Why is this and what should I do?
The cause is usually that the impeller is blocked with debris e.g. dirt or stones.
Solution: pull out the mains plug disconnecting from any power. Check and follow the relevant pages in the operating instructions. Disassemble the bottom of the pump carefully and clean the impeller chamber, then reassemble carefully.
Can my pump be set up and stored anywhere?
Garden pumps, electronic pressure pumps and pressure tank units should not be exposed to rain. The location for your pump should be dry, clean and frost-free.
How should I care for my pump before and after use?
Pumps should be drained of water after use. After pumping chlorinated water from a swimming pool, the pump must be flushed with warm (but not hot e.g. 35˚C or above) fresh water. Intake filters should be cleaned regularly.
How does the float switch on a submersible pump work?
The float switch acts as a sensor which rises and falls with the water level for automatic cut in and cut out of the pump’s operation. It consists mostly of a hollow floating body with an internal switch.
What are the differences between garden pump models 3000/4 and 3500/4?
Although quite similar, the two GARDENA garden pumps have the following differences:
• The litres per hour capacity
• Water pressure
• Number of pump outlets (there are two outlets on 3500/4 model)
When water needs to be pumped further or at higher pressure then the 3500/4 should be selected.
Can I use my 13mm garden hose on the pump outlet?
Yes on most pump models, however a 19mm hose is always recommended as the larger hose diameter maximises performance and allows the water to be pushed out at the optimal pressure.
