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.
NOTICE!
Ambient conditions
Possible consequence: Property damage and
increased wear and tear
Assembly is to be carried out in the following order.
If the pump has to be installed outdoors, then it is
to be equipped with protection against sunlight and
weather influences.
When positioning the pump, ensure that sufficient
room for access is provided for all types of mainte‐
nance work.
Nominal width of the pipework
Make sure that the threaded connectors do not
reduce the nominal width of the pipework or the
double diaphragm pump.
Dimensioning of the suction side
Design the suction side to be generously sized.
Ensure that the supply to the double diaphragm
pump with the liquid to be pumped is ensured
under all load and operating statuses. Ensure that
the inside diameters of the suction lines are gener‐
ously sized.
Install the double diaphragm pump as close as possible to the
medium to be pumped to ensure a maximum service life of the dia‐
phragm. The minimum air pressure to operate the double dia‐
phragm pump is approximately 1.5 bar.
