Correct securing of the device
Only switch the device on if it has been properly
fastened to the ground or its holding fixture. The
system operator is responsible for ensuring that
the ground and the fittings can hold the device
safely and under all operating conditions.
NOTE: The operator of the system must ensure that they have
appropriate installation material available (rawlplugs, screws etc.).
Use appropriate installation material to fasten the double dia‐
phragm pump in place. Tightening torque 20 Nm.
NOTICE!
Outdoor installation
Possible consequence: Damage to property and
increased wear.
Install the unit indoors. If the pump is to be
installed outdoors, make sure that it is protected
against sunlight and weathering.
When positioning the pump, ensure that there is
sufficient room for access for maintenance work.
- 10 °C ... 40 °C
< 95% relative air humidity (non-condensing)
1.
Configure the threaded connectors to ensure that they do not
reduce the nominal width of the pipework and the double dia‐
phragm pump.
2.
Design the suction side to be generously sized. Ensure that
the supply to the double diaphragm pump with the medium to
be pumped is ensured under all load and operating statuses.
Ensure that the inside diameters of the suction lines are gen‐
erously sized.
3.
Install the double diaphragm pump as close as possible to
the medium to be pumped to ensure the maximum service
life of the diaphragm. The minimum air pressure to operate
the double diaphragm pump is approximately 1.5 bar.
