On the product pages, the series and models are explained together with technical data, performance diagrams and dimensioned drawings. In order to interpret the technical data correctly, the following explanations may be useful.
| Air flow | Air
flow in reference to the corresponding operating pressure.
|
| Operating pressure | Pressure range at which the diaphragm pump can operate continously. Special care is necessary, when the pump is operating over the stated working pressure or at dead head (zero airflow). Please enquire for special cases. |
| Maximim
pressure
|
Possible
maximum pressure with zero air flow (to be considered as a reference value
only).
|
| Open
flow
|
Amount of air volume at open airflow (zero pressure). |
| Power consumption | Input wattage that appears
at the stated pressure. An exact curve about
power consumption is availabe on request. Remark: The power consumption is
at highest at open flow and at lowest at zero flow!
|
| Duty cycle | The
pumps are designed for permanent operation basically. The operating
conditions (pressure/vacuum, temperature, etc.) should lie within the given
limits.
|
| Life expectancy | The
working life depends on the operating conditions and the work environment,
such as: duty cycle, operating pressure or vacuum, ambient temperature,
air quality, ventilation, maintenance, etc.
|
| Power supply | All
data given refer to an electricity supply of
230 VAC/ 50 Hz. Variations in the supply voltage up to +/- 10% are
acceptable. All models also run with a frequency of 60 Hz,
however with correspondingly varying performance.
|
| Insulation class | All
models have the insulation class "E" (corresponds to a
temperature limit of 120°C).
|
| Protection degree | Phoe-niX
series = IPX4; SLL series = IP45; EL series = IP44
|
| Ambient temperature | The
maximum ambient and suction temperature ranges from -10 to +40ºC.
|
| Overload protection | The
SLL, SV and EL-series are supplied with a thermal overload protection.
The contacts breaks when the temperature of the windings reaches hazard
value of the probe at 130°C. After the coil is cooled down below 120°C,
the blowers starts again automatically.
|
| Protective switch (auto stopper) | The
EL series is supplied with a protection switch, in case of a diaphragm
break. It
consists of a micro switch, which turns off the blower. Due to the fact, the blower is protected against
further deviations.
|
| Fault alarm lamp | The
EL series may optional be provided with a fault alarm lamp. these air
pumps will indicate any diaphragm fault of the linear motor with a signal
lamp, placed on the outside cover of the air pump.
|
| General remarks |
The information presented on this webpage is based on technical data and test results of nominal units. Customer-specific modifications can lead to deviations. The measured values refer to the mentioned power supply and an ambient temperature of 15 to 25°C. The volume flows were measured with air. Subject to technical alterations. |
